It may be listed under the nomenclatures 17b-hydroxy-5a-androst-1-en-3-one and 5a-androst-1-en-3-one, 17b-ol. 1-Testosterone is the 5a reduced form of boldenone (Equipoise). 1-Testosterone was the first fully active steroid introduced to the dietary supplement market, and it was only sold over the counter for only a couple of years before being banned in early 2005.

1-Testosterone has an anabolic to androgenic ratio of 200/100. With 1-testosterone, many users report a hardening effect and an increase in vascularity. 1-testosterone appears to be best used for size gains, although it should still provide the user with strength gains as well. In effect, 1-testosterone has been compared to Primobolan and Equipoise, though overall it is a much more potent compound mg for mg. 1-testosterone is considered a “dry” compound which can be used during cutting phases yet because of its strength is can also be useful during a bulking phase.

With its favorable anabolic to androgenic ratio, the low doses needed to see results, and the fact that 1-testosterone is already 5a reduced, androgenic side effects should not be too high with this compound in comparison to other steroids like testosterone. 1-testosterone cannot convert to estrogen, so the user should not experience bloating while on cycle and the risk of developing gynecomastia is low when 1-testosterone is used alone. One side effect commonly experienced by 1-testosterone users is lethargy. The exact reason for this lethargy is unknown, but it may be due to the fact that 1-testosterone lacks the energy and libido boosting effects of testosterone yet is still suppressive of natural testosterone production, or because of low estrogen levels. Stacking 1-testosterone with a more androgenic compound during a cut or a “wet” compound during a bulk does appear to relieve the issue of lethargy in most users.

Orally, 1-testosterone hes a very short half-life and is not very bioavailable because it is not methylated to avoid breakdown by the liver. When 1-testosterone is administered as a transdermal (absorbed through the skin), bioavailability is increased but its short half-life is still an issue. 1-testosterone was also sold as an injectable as 1-testosterone cypionate, which greatly increased half-life to about 4-5 days, making this the most effective way to use 1-testosterone. When injected, only 100-200mg/week is needed for an effective cycle.

1-Testosterone was included in the Anabolic Steroid Control Act of 2004, and was banned as of January 20th, 2005. 1-Testosterone is still available on the black market as injectable 1-testosterone cypionate, but it is no longer available as an over the counter dietary supplement. While 1-testosterone and its direct prohormone 1-androstenediol are banned, 1-DHEA(1-androsterone) is still legally available and converts to 1-testosterone in a two step process.
