Testosterone Phenylpropionate[edit]

Testosterone Phenylpropionate is a form of testosterone, which was first released under the trade name "Testolent" by a pharmaceutical company “Sicomed Pharmaceutical house”. Until recently, testosterone phenylpropionate was a rarity on the black market, but the current availability of precursors for the synthesis and the appearance of numerous clandestine laboratories have made this version of testosterone more accessible. Chemically the drug is a connection of testosterone with phenylpropionate ester, which is much more common in conjunction with nandrolone (Durabolin).

This testosterone ester is active for 4-5 days. It is something between testosterone cypionate and propionate. The drug may be useful for athletes who like propionate but don't like the high frequency of the injections. Based on experimental data, the best results are achieved if the injection are performed every third or fourth day, or about twice a week. In addition to features of the ether moiety, testosterone phenylpropionate is slightly different from other forms.

According to the athletes, the drug causes less water retention than testosterone cypionate or enanthate. Lean muscle results are the same as when propionate is used.

Mechanism of action[edit]

Testosterone Phenylpropionate has an effect on the muscles by increasing the delay of nitrogen in muscles. Testosterone also increases the level of IGF-1 in the muscle tissue and the liver. Testosterone, regardless of ester, also has the ability to accelerate satellite cell division, which are important in the repair of damaged muscle.

Side effects[edit]

Testosterone can be converted to estrogen in the body (a process known as aromatization) and in dihydrotestosterone (due to operation of the enzyme 5-alpha-reductase). Estrogen is the cause of many side effects, such as gynecomastia, water retention, etc. While dihydrotestosterone sometimes causes hair loss on the head, enlarged prostate, and others.

A common athletes’ complaint is pain at the injection site. Perhaps it is a development of an abscess.


Due to the growing popularity of the drug on the black market, as well as increased availability, the price of Testosterone Phenylpropionate is constantly decreasing, so it can be assumed that it will be quite popular in the coming years.

As mentioned above, this steroid is similar to the Propionate in many ways, this explains why it is often used during cutting, although it is also well suited for muscle mass gain. It can be combined with other anabolic agents, as well as used solo. The average duration is 6 weeks. Dosage - 200 mg every third day.

It is necessary to use anti-estrogens and gonadotropin during prolonged cycle.
