Characteristics

Halodrol is a 17aa steroid that converts to the steroid oral Turinabol after interaction with 3b-HSD at an estimated rate of about 5%.

Because of this low conversion, doses must be higher than other 17aa pro-steroids. However, it is suspected that Halodrol has decent potency without conversion as good results are seen despite the relatively low conversion to Turinabol. Based on Vida’s data Halodrol appears to be about as potent as testosterone, and significantly less androgenic.

Because of the 4-chloro group, halodrol has no progestational effects, it cannot interact with the aromatase enzyme, and it produces inactive 4-chloro-DHT metabolites. This makes androgenic side-effects such as hair loss, high blood pressure, acne and prostate enlargement less likely. Anecdotal reports would also have us believe that side-effects with this compound are fairly mild.

Although caution would still need to be had, the low androgenic value of this compound would also make it one of the more appropriate anabolic steroids for women wishing increase lean mass yet avoid a deeper voice, increased hair growth, acne and clitoral growth. (Oral Turinabol was actually the preferred steroid for Olympic female athletes in East Germany)

The lack of androgenic potency might be expected to create problems with gyno, however the low SHBG binding affinity has minimal interference with SHBG levels and/or freely circuiting estrogen and testosterone. It does not appear that halodrol has a significant gyno risk.

Because halodrol must be used at such a high dose to see noticeable effects, liver toxicity may become an issue. Therefore it is recommended to use a liver protecting supplement before and during halodrol cycles.

Gains from Halodrol generally take a few weeks to notice, but users can expect solid increases in strength, lean muscle mass, improved vascularity and minimal water retention. This allows some of the gains to be kept after the cycle if good diet and training are continued. Quick dramatic gains in size and strength are not generally noticed with Halodrol.

It is used successfully as a standalone, but would be expected to stack well with most other steroids, except 17aa oral due to liver toxicity concerns.

Characteristics

4-DHEA is a naturally occurring non-methylated (non-17aa) pro-steroid.

4-DHEA, like DHEA, requires a 2 step conversion process involving 3b-HSD and 17b-HSD to convert it to Androstenedione/androstenediol, and then testosterone. What makes 4-DHEA slightly different from DHEA is a double bond in the 4th position rather than the 5th. This makes 4-DHEA less estrogenic by not acting directly upon the estrogen receptor like DHEA has been found to do.

Although 4-DHEA can aromatize to estrogen it is probably not enough to cause high estrogen related side-effects.

Overall results will be similar to or the original 4-AD banned back in 2004. Higher doses of this compound will produce fairly lean gains in muscle mass, with moderate improvements in strength. This product may produce some bloat from the estrogen conversion, which could be countered by administering an aromatase inhibitor, but this will largely defeat the purpose of using this compound to begin with.

Since this compound is naturally occurring and non-methylated overall side-effects will be fairly mild. However, high doses may also lead to oily skin, acne and increased blood pressure. Because this steroid is non-17aa there should be less concern about it negatively affecting the HDL/LDL ratio.

Because this compound can convert to testosterone it can also convert to DHT and other 5a-reduced metabolites. This can serve as a good stack with progestational or relatively non-androgenic compounds that may create problems with libido or gyno because of lacking androgenic potency.

Although this compound is relatively safe and moderately effective, its high cost has probably been the reason for its lack of popularity.

Characteristics

Promestanolone is a 17aa pro-steroid which converts to the illegal anabolic steroid methyl-DHT (mestanolone).

There is no human clinical data on promestanolone, but it is most likely exerting its effects by converting to methyl-DHT. The acidic environment in the stomach would be responsible for converting the 3-hydroxyimine group to a 3-one — thus rapidly changing it to methyl DHT. Therefore results and side-effects would be considered to be very similar to methyl-DHT.

Although DHT can be deactivated in skeletal muscle tissue by 3b-HSD it is likely that this enzyme pathway can be overwhelmed if this compound is taken at a high enough dose. Methyl-DHT has some activity on the progestin receptor, but not to a high degree. It has moderate anabolic but high androgenic effects. It binds strongly to SHBG, therefore free testosterone and estrogen can be expected to rise by displacement from SHBG.

Since this is a 17aa compound, liver toxicity will be an issue with high doses or long term use. For this reason users should consider priming the liver with a liver supporting supplement before and during a Promestanolone cycle. Users will also experience minimal subcutaneous water retention since there is no conversion to estrogen. However, intracellular water and sodium retention will increase by inhibition of 11-beta hydroxylase and mineralocorticoid build up.

Users may also experience an increase in aggression and mood swings which is a common side effect of many steroids with high androgenic value. This makes this compound an excellent pre-lifting or pre-competition steroid.

Promestanolone should produce solid lean gains in muscle as a standalone. However for those looking to add additional bulk to their cycle, promestanolone would stack with with virtually any other non-17aa oral.

Characteristics

Methyl-1,4AD is a 17aa pro-steroid that converts to the illegal anabolic steroid methandrostenolone (Dianabol) at a rate of about 15-20%. It takes one conversion with 3b-HSD to convert methyl-1,4AD to Dianabol which probably happens fairly rapidly in the liver.

Since the average dose of Dianabol is generally 25-50mg/day with most steroid users, it is recommended to use this compound at 2-3x the dose for noticeable effects. While Methyl-1,4AD may have some activity on its own, it would be considered pretty weak until it makes the conversion to Dianabol.

Although this compound does not appear to have any progestational effects, it can convert to estrogen (methylestradiol) at a fairly decent rate. If users are very sensitive to estrogenic side-effects then an aromatase inhibitor may be taken along with this compound. However, if one is using an anti-estrogen with this steroid it begs the question, “why chose this steroid to begin with?” Most of the weight and size gains from this compound come from its estrogen conversion, therefore using an AI would noticeably limit the gains from this compound.

This compound has moderate androgenic effects, therefore users who are sensitive to hair loss should be careful with higher doses. The combined estrogenic and androgenic effects of this compound may lead to excessive prostate swelling, so frequent visits to the bathroom may become a problem. (although all steroids have this effect to degree)

Since this compound readily converts to estrogen it will likely have a lubercative effect on joints, contrary to many modern designer steroids that do not convert to estrogen and tend to cause joint pains. This would make this compound a good choice for bulking cycles where joint comfort is important for heavy weight lifting.

Because higher doses are needed with this compound, more stress is placed on the liver. As with any 17aa oral it is recommended to pre-condition the liver with a liver supporting supplement.

Users who use this at higher doses will experience similar gains to Dianabol including rapid increases in strength and size. Side-effects may include rapid weight gain, increase in blood pressure, bloating, back pumps and acne.

This compound could be used as a standalone for a bulking cycle, however users should be aware that much of the bloat and size gains from Methyl-1,4AD will be quickly lost after a cycle.

Transdermal Steroids – Expanded

If there is one topic that is misunderstood in the steroid community, it’s Transdermal Steroids (TS’s). The value of TS’s are under-estimated, and the science has been over looked by the vast majority. In this article, I intend to shed some light on TS’s and introduce a few new transdermal options that can offer benefits to athletes, bodybuilders and HRT patients alike.

As a developer of several transdermal products, and a counselor to a number of TRT patients; I’ve learned that a majority of men consider Androgel™ and Testim™ the only real viable topical hormones. This makes sense, being they are the most popular FDA approved testosterone gels currently available. However, there are more options to be considered. Steroid hormones such as nandrolone and boldenone offer useful advantages when delivered topically. Legal prohormones such as DHEA and pregnenolone can also offer great benefits when used topically (Found in Dermacrine). One benefit with all TS’s is their quick clearance from the body (generally less than 72hrs for most hormones). This is advantageous for PCT, when the quick clearance of hormones is desired (often a problem with long-acting injectable steroids which may take months to clear the system.)

Before we review some of the alternatives to testosterone gel, let’s take a quick look at some basic rules so we can have a better understanding of how we can manipulate the hormonal effects for our best interest.

Application site –

The site of application is one way to maximize the effectiveness of our topical hormones, while also altering the action the hormone has on the body. For instance, the skin on the front of the neck is thin and very vascular, making it ideal for systemic transdermal delivery. The skin on the shoulders and upper back – areas where you may have had acne as a teenager — are highly concentrated with steroidogenic enzymes such as 3b HSD and 17a HSD. These are the enzymes required to make hormonal conversions, such as DHEA > androstenediol > testosterone. On the flip side, the stomach area tends to carry a higher amount of the aromatase enzyme, especially if you’re prone to holding fat in the abdominal region. This would be an area to avoid applying testosterone gel, since the increased aromatase activity could increase the conversion to estrogen.

One area which can be advantageous to use for topical application is the scrotal skin. This area is extremely thin and easily penetrated by topical ingredients for systemic delivery. In fact, its absorption rate is about 4-5x more than anywhere else on the body. (1,2) This makes it the perfect spot for the delivery of topical ingredients, giving you more bank for the buck.

One thing to be aware of with scrotal applications is the higher conversion rate to DHT when applying testosterone to this area. There is heavier conversion to DHT because the scrotal skin carries a high concentration of the 5a-reductase enzyme. When the testosterone travels through the scrotal skin it interacts with the 5a-reductase enzyme and converts to DHT. This gives you a significant spike in DHT when you apply testosterone cream to your scrotum, which may or may not be a good thing. (see below for alternatives to testosterone and how to avoid the DHT)

An enlarged or irritated prostate is generally a symptom associated with high DHT. However, the DHT may not be entirely to blame. In fact, research has shown that topical DHT treatment can actually keep the prostate healthy and even reduce its size, as long as estrogen levels are also kept in control. (3,4) Plus, DHT is an antagonist of estrogen, so it’s going to help reduce gyno (male breasts) and water retention, while it also increase libido and erectile function. It could even be argued that DHT is more critical to a man’s well-being than testosterone.

Unfortunately, DHT can increase hair loss if you’re genetically prone to it, although this could be prevented if DHT levels are kept in range, bringing us to the next topic – the progesterone/DHT relationship. That’s right, progesterone can be healthy for a male too.

The word progesterone may sound frightening to some since it’s primarily known as a female hormone. However, it also offers health benefits for the male if used in very low and controlled amounts. You see, progesterone can naturally inhibit the conversion of testosterone to DHT thus helping to keep DHT in a healthy range (similar to finasteride albeit to a lesser degree). So how does this apply to real life?

Well, pregnenolone cream is legal and readily available in most counties, and as it passes the skin, pregnenolone readily interacts with the skins enzymes (3b HSD) and makes partial conversion to progesterone. (The reason for applying pregnenolone rather than strait progesterone is the added cognitive enhancements of pregnenolone.) In most cases, a 10-20mg application of pregnenolone cream would convert to sufficient amounts of progesterone to control DHT conversion from testosterone supplementation. (given via IM or topically)

If for whatever reason you don’t want to deal with combating DHT, or are extremely sensitive to its hair loss effects, you may want to consider using nandrolone or boldenone for topical application as alternatives to testosterone. If you’re lucky enough to have access to nandrolone or boldenone base powder, they are easily compounded into a topical and are perfect for transdermal delivery. These hormones are gentler on the hairline because they don’t convert to DHT. More specifically, when they interact with the 5a-reductase enzyme, they are converted to a less powerful 5a-reduced steroid, thus being ‘gentler’ than testosterone. Note: Nandrolone (Deca) can be a double edged sword given that it lacks a powerful 5a-reduced metabolite. It’s beneficial for preventing hair loss, but notorious for erectile dysfunction causes known as “Deca Dick”.

If you’re interested in staying legal and you don’t have access to AAS’s such as testosterone, nandrolone or boldenone, then DHEA is an excellent legal alternative, especially when used as a transdermal. When taken as a transdermal, DHEA is absorbed about 10x better than when taken orally. (5) Plus there is the additional benefit of increased metabolic conversion of hormones when they are taken through the skin. (6) As mentioned earlier, the shoulder and upper back skin have the highest concentration of enzymes required to make hormonal conversions (3b HSD & 17b HSD). Since DHEA is an immediate precursor to several anabolic hormones, the topical application of DHEA can cause a sharp rise in androstenediol, androstenedione and testosterone within a few hours of application. (These are the primary hormones that make Dermacrine so effective)

Remember, no matter what hormones you choose, be aware of moderation and balance.
