Like other AAS, boldenone is an agonist of the androgen receptor (AR).  The activity of boldenone is mainly anabolic , with a low androgenic potency. Boldenone will increase nitrogen retention, protein synthesis, increases appetite and stimulates the release of erythropoietin in the kidneys.  Boldenone was synthesized in an attempt to create a long-acting injectable metandienone , for androgen deficiency disorders. Boldenone acts similar to metandienone with fewer adverse androgenic effects. [ medical citation needed ] Although commonly compared to nandrolone , boldenone lacks progesterone receptor interaction and associated progestogenic side effects.
The use of products such as Finasteride and Human Chorionic Gonadotropin (HCG) help reduce or completely eliminate these negative side effects caused by increased DHT levels. As always proper post-cycle therapy will help Testoviron users recover to a fully functioning natural Testosterone production. It is not recommended that women use Tesoviron or any Testosterones. There is a high probability that severe negative side effects will occur with even moderate doses. Deepening of the voice, body and facial hair growth and enlargement of the clitoris are all possible side effects of testosterone use and for the most part are irreversible.
There are several possible androgenic side effects of Testoviron and they are dependent on genetics. The androgenic side effects of Testoviron include hair loss, acne and body hair growth. Hair loss is not possible if you are not predisposed to male pattern baldness. If you are genetically predisposed to male pattern baldness you may find Testoviron causes you to lose some of your hair sooner than you would have, but you were going to lose it at some point anyway. Acne is similar; if acne sensitive you may find issues on your back, shoulders or chest. Staying clean and dry is very important if you are sensitive.
Important Note: Low testosterone levels can also promote hair loss.
The androgenic side effects of Testoviron are due to the testosterone hormone reducing to dihydrotestosterone (DHT). This occurs due to the hormone being metabolized by the 5-alpha reductase enzyme. 5-alpha reductase inhibitors like Finasteride can be used to reduce the androgenicity of the testosterone hormone if needed. However, this can potentially cause hormone imbalances if not carefully used.
The androgenic side effects of Testoviron also include virilization in women. Women who use Testoviron are almost assured virilization symptoms, which may include a deepening of the vocal chords, body hair growth and clitoral enlargement. This isn’t a commonly recommended hormone for female use.
