What is the AndroStat?

The AndroStat is a questionnaire designed to estimate your average total testosterone level.

It has proven to be exceptionally accurate for predicting the average total testosterone levels in men — being anywhere from 80-100% correlated to lab values for most men.

In fact, we predict that the AndroStat can give a more accurate assessment of your average monthly total testosterone level than a single blood test from the lab.

How can the AndroStat be more accurate than a blood test?

Simply because a blood test is not a true representation of your average monthly or daily testosterone levels. Rather, a single blood test only represents your testosterone level at that very moment.

Research shows that testosterone varies by as much as 25% throughout the day, or possibly even more given physiological or environmental influences. (43,44) For instance, very few individuals enjoy blood tests, and some can become quite anxiety ridden even thinking about blood tests — which can quickly reduce testosterone by causing an immediate surge in stress hormones.

Things that can immediately influence blood testosterone levels include –

  • Stress/anxiety associated with the test itself
  • Quality of sleep from the night before
  • Drug use
  • Exercise
  • Meals

Any of these factors can negatively influence testosterone levels and give a result that is not truly representational of your average daily testosterone levels.

How does the AndroStat estimate total testosterone levels?

The AndroStat calculates total testosterone levels based on data gathered from dozens of studies, including thousands of men. It takes into account a large number of testosterone altering variables including age, body composition, BMI, smoking, exercise, stress, socioeconomic status, etc. The data from the studies was combined in to a mathematical equation that make up the power formula behind the AndroStat. (1-24)

During the development of the AndroStat, we had our AndroSeries v3 product testers (15+) and a number of volunteers complete the questionnaire, and verified the results against their actual blood values for total testosterone. We used this random sampling to verify and calibrate the AndroStat formula for a high degree of accuracy.

Editorial note: Id like to give special credit to Ken Hess, who painstakingly cross examined dozens of research papers to find the strongest correlates for predicting total testosterone levels.

What does the AndroStat have to do with AndroSeries products?

Knowing your testosterone levels helps determine the optimal dose for AndroSeries products.

For instance, men with low androgens (e.g. testosterone) will naturally get more benefit from a lower dose — partly because they are more sensitive to the effects of androgens — and they don’t need as high of a dose to surpass the androgen threshold.

On the other hand, men with higher androgen levels will require a higher dose to see the same dramatic benefits — partly because they are accustomed to the effects of high/normal androgens — and they need a higher dose to surpass the androgen threshold.

NOTE: Many of the immediate effects, like increased sex drive or aggression may not be noticeable to a man with high androgen levels — as these aspects may already be optimized, where further androgens may offer no additional benefit. However, these men can still reap physical benefits from androgen supplementation. These are considered the long-term benefits from androgens.

What is the "androgen threshold"?

The "androgen threshold" is the amount you need to boost your androgen levels in order to see significant improvements in body composition and strength. (25-27)

Research shows that androgen levels (e.g. testosterone) must increase by 1000-1300ng/dl above your current level, to increase lean body mass by 10%, drop total body fat by 10%, and increase strength by 30%. (25-27) This research is based on androgen supplementation for a 16 week period, with no dietary or training intervention. However, research suggests that combining androgens with exercise and dietary intervention can accelerate the achievement of these results. (28-30)

Consider this example subject –

Beginning stats

  • 175lbs with 500ng/dL total testosterone
  • 35lbs body fat (20%)
  • 140lbs lean body mass (80%)

Subject increases his androgen levels to 2700ng/dL (6 softgels of AndroMass for 8 weeks)

Stats after 8 weeks on AndroMass

  • 186lbs with 2700ng/dL Testosterone
  • 32lbs body fat (17%)
  • 154lbs lean body mass (83%)

Therefore, since this subject increased his androgen levels by 2200ng/dL above his natural androgen level the subject was able to reduce his body fat by about 9% and increase his lean body mass by about 10%. These results may be considered normal results from an 8 week cycle of AndroMass combined with resistance training and a lean muscle promoting diet.

I got my AndroStat results, but what do they mean?

Please refer to the Your Testosterone Levels — Killing or helping you? article for interpretation of your testosterone levels.

How much will the AndroSeries products increase my "testosterone"?

AndroSeries products are rated based on "testosterone equivalent" values. This value represents the total combined androgenic, anabolic and estrogenic bio-activity for the 24hr period.

In other words, we have gone through the painstaking effort to calculate the power of each AndroSeries pill relative to its total "testosterone-like" activity.

Here are the "testosterone equivalent" values established for the AndroSeries products –

  • AndroDrive – 217 ng/dL
  • AndroHard – 375 ng/dL
  • AndroLean – 334 ng/dL
  • AndroMass – 450 ng/dL
  • AndroBulk – 450 ng/dL

The reason for using a "testosterone equivalent" value is to give a realistic expectation of results and effects that will be noticed relative to other popular forms of testosterone, such as injectable, topical or oral testosterone. It is important to note; AndroSeries products do not work by increasing testosterone levels alone. Rather, AndroSeries exert most of their effects by converting to other androgens which have similar effects as testosterone — resulting in similar effects on the body. (31-42)

Finally, these values only represent TOTAL combined androgenic, anabolic and estrogenic effects. Remember, each AndroSeries product has a different ratio of androgenic, anabolic and estrogenic effects — as seen here in the AndroSeries Effects Chart.

How do I determine proper dosages for AndroSeries products?

Carbs Plus Stress Increases Estrogen

If you are a person who wants to attain a leaner, more define physique, than you need to take action to lower cortisol levels and lower your carbohydrate consumption.

                     … And here is why 

There was a fascinating study performed by researchers from the University of Birmingham that examined Glucocorticoid (cortisol) & insulin regulation and how it affects aromatase activity in human adipose tissue, revealing different outcomes in men and women.

In this study, researchers wanted to examine insulin & cortisol’s role in potentiating aromatase activity in men and women by taking samples of subcutaneous and omental (visceral) adipose tissue for rigorous testing.

The research candidates were premenopausal women (7) and postmenopausal women (10) and 9 men.  The researchers found that the male candidate’s basal aromatase activity was significantly higher in the subcutaneous tissues opposed to omental (visceral) tissue with cortisol + insulin present. Insulin appeared to exacerbate cortisol’s effect in promoting aromatase activity.

The female test subjects had similar results as the males, but even more aromatase activity with insulin + cortisol present. This small piece of the study reveals that subcutaneous adipose tissue has a much greater affinity for aromatase activity than omental (visceral) fat in both genders.

When they examined the differences between pre & postmenopausal women and their reaction to insulin + cortisol the results revealed that postmenopausal women had high aromatase in the omental (visceral) tissues than premenopausal women. However both pre & postmenopausal women revealed the same response to aromatase activity in the subcutaneous tissues.

Sex steroids such as Dhea, Androstenedione, Estrone, Testosterone etc… may regulate adipose mass by increasing preadipocyte proliferation, differentiation, and adipocyte size through effects on lipolysis (fat-loss) and lipogenesis (fat accrural).

Insulin plays a crucial role in adipocyte proliferation and differentiation, however in this study, insulin ALONE has no effect on aromatase expression, whereas insulin + cortisol demonstrated an additive effect on aromatase activity.

You know what that means for most people who utilize high carbohydrate diet’s to either keep dietary fat low or to gain weight?

It means that relatively high doses of insulin (think dextrose & white rice) in combination with cortisol (think low blood sugar from spiked insulin) increases aromatase activity, which promotes estrogen levels in excess.

This is extremely undesirable for favorable body composition as this phenomenon will promote proliferation and differentiation of preadipocytes, enhancing central adiposity (fat mass accrural).

  Now what you should do

I hope after reading this article you recognize that ingesting copious amounts of carbohydrates in your plight for ultimate muscle mass or general health (because you still abide by the USDA outdated food pyramid which is simply asinine) you understand that manipulating your insulin and cortisol levels through meticulous nutrition planning will be in your best interests.

I am NOT telling you to switch to an Atkins or Ketogenic Diet by any means, simply just to pay attention to your carbohydrate choices (high glycemic VS low glycemic) and also your glycemic loads (grams of carbs per meal). If you absolutely insist you MUST incorporate carbohydrates around the clock with each meal, make sure to keep the gram allotment low, at around 20-30 grams per meal, as this keeps the glycemic load under control. Also, employ high glycemic carbs ONLY around your weight training or high activity event. The remainder of your carbs (if you insist you need them) should be low glycemic.

I would suggest you to just use carbohydrates INFREQUENTLY, meaning pre & post training, while the rest of your meals consist of top quality protein sources and raw, undenatured fats.

Incorporating a supplement that increases growth hormone production while lowering the stress hormone cortisol would be beneficial for those striving to get as lean as possible while dieting for fat-loss or gaining mass while keeping body fat lower.

Look no further than Primordial’s EndoAmp Max, which will do just that – Increase GH & lower cortisol, while enhancing mental acuity and focus.

  Helpful tips to lower cortisol & insulin –

  • Deep tissue massages will relax your muscles and mind, which will lower cortisol

  • Keeping the glycemic load small at each carbohydrate meal will keep insulin stable

  • Sleeping in a silent pitch black room will initiate high quality sleep for lowering cortisol and boosting GH release

  • Combining essential fats to each low glycemic load meal will further lower insulin release

  • Supplementing with adaptogenic herbs such as magnolia bark & rhodiola lower cortisol

  • Incorporating fiber into each meal will keep insulin levels low

  • Supplementing with Primordial Performance EndoAmp will boost GH & lower cortisol

What is the difference between DHEA 1-DHEA 4-DHEA R-DHEA and 7-DHEA?


DHEA
(dehydroepiandrosterone)
(Super-5-DHEA†)
 
Main effects
 
+ Anti-aging (youthful energy)
+ Exercise endurance
+ Recovery
+ Fat loss
+ Muscle sparing (anti-catabolic)
+ Immune system
 
 
Primary metabolite –
 
5-androstenediol (5-AD)
 
Description –
 
DHEA is considered "generic" or regular DHEA. It can technically be called 5-DHEA, since the double bond is located in the 5th position. 
 
DHEA has been popular in the life extension crowd since the 1980’s. It's typically used for its ability to support energy and general wellbeing at a dose of 50-100mg/day. (1-3) More recently, higher doses of DHEA have been used to improve body composition due to DHEA’s mild anabolic and thermogenic effects. (1, 4) This makes DHEA an excellent choice for cutting during a calorie deficient diet, since DHEA has good muscle sparing properties. (1, 17)
 
DHEA converts to testosterone at a rate of about 1%, however it has high conversion to 5-androstenediol, where it gets its mild androgenic and anabolic effects. (5-8) DHEA’s thermogenic properties come from its conversion to 7-oxo-DHEA. (4)
 
Due to DHEA’s mild androgenic effects it rarely produces hair loss or acne. Although DHEA has moderate estrogenic effects, it rarely produces gyno or undesirable estrogenic side effects.(1-3) Some more sedentary users have reported anxiety or sleeplessness with DHEA, which is likely related to the neurosteroid activity in the brain. (3) However, this effect is also reported as “motivational energy” which is a frequently reported benefit of DHEA. 
 
Because of DHEA’s wide range of benefits and its balanced hormonal properties it can easily be used for cutting, or to keep gains lean during a lean mass building cycle.
 

4-DHEA
(4-dehydroepiandrosterone)
(Super-4-DHEA†)
 
Main effects –
 
+ Muscle mass (nitrogen retention)
+ Strength
+ Blood volume (hematopoietic)
+ Recovery
+ IGF-1 & GH
 
 
Primary metabolite –
 
4-androstenediol (4-AD)
 
Description –
 
4-DHEA is a naturally occurring DHEA isomer. It’s structure closely resembles regular DHEA but the double bond in the 4th position dramatically changes its effects.
 
4-DHEA readily converts to 4-androstenediol, rather than 5-androstenediol, boosting its anabolic potency more than 2x over regular DHEA. (6-8, 11) 4-DHEA is also expected to have a higher conversion rate to testosterone compared to regular DHEA. (6, 7) The 4-DHEA also lacks the calorie burning thermogenic properties, therefore offering superior calorie retention for a bulking effect. (4) This increased anabolic potency and reduced thermogenic action will lead to noticeable gains in strength, lean tissue growth, and weight gain. 
 
4-DHEA will have mild estrogen conversion that can be easily balanced with a non-aromatizing steroid like androsterone or 1-DHEA. Overall gains will be similar to the original “4-AD” banned in the 2004 Steroid Control Act.
 
As with the other DHEA isomers, 4-DHEA is naturally occurring and non-toxic. (9) Side-effects such as oily skin or reduced fertility are considered mild and temporary. The most notable side-effect would be suppression of natural testosterone production, which makes PCT necessary after a cycle. Overall 4-DHEA is a very safe and effective lean muscle building agent.
 
The only downfall to 4-DHEA is its high cost due to the high dose that is required to see significant muscle building effects.
†:The “Super” (ex., "Super-5-DHEA") signifies a fatty ester attachment to the steroid molecule to assist in bioavailability.

1-DHEA
(1-dehydroepiandrosterone)
(Super-1-DHEA†)
 
Main effects –
 
+ Muscle mass (nitrogen retention)
+ Strength
+ Hardening
+ Bloat reduction
+ Recovery
 
 
Primary metabolite –
 
1-androstenediol (1-AD)
 
Description –
 
1-DHEA is a naturally occurring DHEA isomer which cannot convert to testosterone or estrogen — but instead converts to the non-estrogenic 1-testosterone. (10)
 
The total conversion to 1-testosterone is probably less than 2%. (6,7) However, 1-DHEA gets most of its effects from conversion to 1-androstenediol, which has potent muscle building and hardening effects in and of itself. (8, 11, 12) 1-androstenediol was sold as “1-AD” prior to the 2004 Steroid Control Act, and was known for producing rapid gains in lean mass with zero water retention or bloat.
 
1-DHEA does not convert to estrogen nor does it activate the estrogen receptor like DHEA is known to do. (13) It could be referred to as “dry DHEA”. Because of this, it will stack well with other estrogenic steroids such as 4-DHEA to produce† clean gains in muscle tissue.
 
As with the other DHEA isomers, 1-DHEA is naturally occurring and non-toxic. (14) Side-effects such as oily skin, reduced fertility or increased hair shedding are considered mild and temporary. The most notable side-effect would be suppression of natural testosterone production, which makes PCT necessary after a cycle. This makes 1-DHEA a very safe, legal and effective lean muscle building agent. Some users have reported lethargy with 1-DHEA. This seems to be less severe when balanced with DHEA or 4-DHEA which tend to have an anti-lethargic effect.

7-oxo-DHEA
(7-oxo-dehydroepiandrosterone)
(Super-7-DHEA†)
 
Main effects –
 
+ Fat loss
+ Weight loss
+ Muscle sparing (anti-catabolic)
+ Immune supporting
 
 
Primary metabolite –
 
Androstenetriol (AET)
 
Description –
 
7-oxo-DHEA is a naturally occurring metabolite of DHEA. It’s well known for its weight loss effect due to its strong thermogenic action. (4, 15, 16)
 
The strong thermogenic effect from 7-oxo-DHEA come from its ability to increase two thermogenic enzymes, which increases the body’s ability to burn off calories as heat. (4) Although DHEA shares a similar effect, 7-oxo-DHEA is about 2.5x more active than DHEA. (4) Human studies have shown that 7-oxo-DHEA can increase weight loss, with a majority of weight loss being actual fat tissue. (15-16) Aside from the thermogenic action, 7-oxo-DHEA also appears to be an aromatase inhibitor, which can reduce estrogen levels. 
 
Because of the modification in the 7th position, 7-oxo-DHEA cannot convert to testosterone or estrogen, nor does it have any androgenic or anabolic effects. (15) Because of this, it does not produce side-effects such as hair loss, acne or prostate inflammation. It also blocks the catabolic effect of cortisol, which helps to retain muscle during a low calorie diet.
 
Side-effects of 7-oxo-DHEA may include anxiety or sleeplessness similar to regular DHEA due to the neuro-stimulating effect. However, this is generally mild, and seems to only occur in some users. Overall 7-oxo-DHEA is very tolerable and safe at the typical 100-200mg/day dose. (15, 16)
 
While 7-oxo-DHEA can be useful for a cutting or weight loss protocol, it would not be wise to use during a bulking or mass building cycle. Its tendency to increase the metabolism and rate of calorie burning will make it difficult to build additional muscle mass. (4)
 
†:The “Super” (ex., "Super-5-DHEA") signifies a fatty ester attachment to the steroid molecule to assist in bioavailability.

R-DHEA
(androsterone)
(Super-R-DHEA†)
 
Main effects –
 
+ Strength 
+ Hardening
+ Bloat reduction
+ Recovery
+ Anti-estrogen
+ Sex drive
+ Aggression 
 
 
Primary metabolite –
 
Androstanediol (5-AA)
 
Description –
 
R-DHEA is known as “Reduced DHEA” because it is a 5a-reduced metabolite of DHEA. It’s more commonly referred to as androsterone.
 
This naturally occurring hormone cannot convert to testosterone, but instead converts to the dihydrotestosterone (DHT). (10, 18) Similar to testosterone, DHT is responsible for masculine traits such as aggression, sex drive, and physical strength. (19,20) However, because DHT cannot convert to estrogen, it also helps reduce fat storage and water retention, making it an excellent steroid for increasing muscular hardness and vascularity. 
 
R-DHEA will stack well with 5-DHEA or 4-DHEA as it will help reduce water retention from under the skin, thus creating a “dry” and hard appearance. R-DHEA also has moderate anabolic properties thus allowing it to help enhance lean muscle gains. (21)
 
Strength gains will also be noticeable with R-DHEA due to its strong androgenic effect which will activate the central nervous system and increase muscular power. (20) This will increase explosive power with minimal bodyweight increase. The increased aggression is typically a welcomed benefit, which manifests as increased confidence and an “alpha male” feeling in sexual and social activities. 
 
The strong androgenic action from R-DHEA will also help support libido and erection hardness. (20) This makes R-DHEA useful to help counter the sexually suppressive effects from other steroids. The powerful androgenic effect will also block estrogenic effects, and help prevent (and reverse) gyno. (22, 23)
 
Side-effects from R-DHEA will be limited to androgenic side-effects such as oily skin, acne, and increased hair shedding if the user is prone. These side effects are mild and temporary for most users.
 
 
†:The “Super” (ex., "Super-5-DHEA") signifies a fatty ester attachment to the steroid molecule to assist in bioavailability.
