Characteristics

ATD is a steroidal aromatase inhibitor, known as a suicidal inhibitor because it permanently binds to the aromatase enzyme.

ATD is used for its aromatase inhibiting and testosterone boosting effect. Its effectiveness at lowering estrogen appears to be stronger than 6-oxo. It converts to 1,4,6-testosterone, which would also be expected to cause falsely high readings for a testosterone analysis.

The 1,4,6-testosterone metabolite of ATD can also bind to the androgen receptor (AR) and induce androgenic (or possibly anti-androgenic) effects similar to what is seen from 6-oxo. This would be expected since 1,4,6-testosterone has about one third the binding affinity for the AR, therefore it may interefere with the anabolic or androgenic action of hormones which bind the androgen receptor.

ATD would also be expected to interfere with production of natural testosterone by acting upon the hypothalamus pituitary testicular axis (HPTA), therefore this compound should not be used during post cycle therapy (PCT), however it could successfully be used during a cycle to help keep estrogen in control. Anecdotal reports and animal studies have also shown ATD inhibits libido and general sexual potency.

Characteristics

Methylepitiostanol is a methylated version of the steroid Epitiostanol. It is readily active and does not require conversion. Under the influence of heat methylepitiostanol readily breaks down to 17a-Methyl-androstan-2-en-17b-ol (DMT), a now illegal anabolic steroid.

It does not aromatize, however it is possible that methylepitiostanol may offset estrogen and testosterone from SHBG thus increase the risk of gyno for certain individuals with high SHBG levels. Gyno symptoms from this compound may also be a result of this compounds inability to form a potent androgen such as DHT (to antagonize the effects of estrogen). However, in other cases methylepitiostanol can be used to prevent or reduce gynecomastia from an estrogenic steroid by acting as an aromatase inhibitor to keep estrogen down.

It is a DHT derivative with a fairly moderate androgenic value so the chances of hair loss may be increased in certain sensitive users. Swelling of the prostate may also become an issue. The powerful estrogen suppressing action of this steroid and its 17aa stucture will cause it to negatively influence the cholesterol profile by lowering HDL and increasing LDL. It has also been reported to cause stiff joints, possibly related to its suppressive effect on estrogen levels.

Anecdotal reports of appetite suppression and general fatigue would lead one to believe that the liver stress from this 17aa compound is rather severe. For this reason it is recommended to use a liver protecting supplement prior to and during the use of this steroid.

Methylepitiostanol has a strong anabolic action that will lead to quick gains in lean muscle mass and strength with very little bloat. The gains will appear with minimal fat gain and increased vascularity.

Because methylepitiostanol can negatively affect joint comfort it is recommended to be stacked with an aromatizing or progestational compound. However, it is not recommended to stack this steroid with another 17aa oral.

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.
