Active substance: testosterone propionate
Tradenames: Agovirin, Androfon, Androlan-50, Testoviron, Testopin
Testosterone propionate has the shortest ester in the esterified testosterone family, and the fastest action. The levels of active steroid levels peak 24-36 hours after administration , but immediately starts to decrease after that period. It has a half-life of 2-3 days. This can be a good thing for those who are sensitive to the side effects of longer testosterone esters (like enanthat and cypionate ), propionate resulting in a far lower water retention and an increase in energy, muscle pumps, appetite and strength after only 2-3 days of administration.
The down side of testosterone propionate is that because of its fast acting nature it requires frequent injections (usually every two days). On top of that the propionate ester irritate the injection site due to its short molecule so it can be painful. Those sensitive to injections find propionate very uncomfortable. Pain and swelling of the area can appear and even a mild fever. This can last for a few days. It is therefore not a good choice for beginners or for those who simply do not like intramuscular injections.
Due to milder androgenic properties it is the only form of testosterone used by female atheltes (however, the use of testosterone by women remains a bad idea).
The dose is 50-100 mg / day. To reduce the number of injections can be administered at 100-200 mg every two days; however, the best method is the daily administration. Constantly rotate injections sites to minimize pain and discomfort.
Side effects, though lower, are the same as with all testosterone esters. Acne, increased aggression, hair loss, water and fat retention , gynecomastia, are al possible. It is not hepatotoxic. Many users say it has less estrogenic side effects then longer testosterone esters, but it is a good idea to have at hand some antiestrogens like Nolvadex. After the cycle a good post cycle therapy is needed.
Propionate cand be used for muscle gains, but it is the testosterone steroid of choice in the cutting phases. It can be stacked with Primobolan , trenbolone, Masteron or Winstrol. For muscle mass it works well with Dianabol, Deca-durabolin or Equipoise.
WARNING! No one can deny: steroids work, and work well. But in many countries they are illegal, and most of the steroids found on the blackmarket are fake and of very low quality. But there are some good news! For those who can not find original steroids, or do not want to be exposed to the risks associated with these substances, there are powerful natural alternatives, legal and without side effects, that will get you fast and lasting results: Probolan 50 and Metadrol for muscle mass, ThermaCuts and UltraSlim for cutting and weight loss.
