Viromone 100 – Testosterone Propionate

Viromone 100 by Syncom Labs is injectable Testosterone Propionate at 100 mg/ml. Propionate is a short ester of testosterone, the base androgen that drives muscle protein synthesis, strength and recovery. Because the ester is short, it releases quickly and clears quickly, so blood levels rise and fall fast rather than staying steady like the long esters enanthate or cypionate.

Because it is a short ester, propionate is injected often, commonly every other day or even daily to keep blood levels flat. Reported doses sit around 300 to 500 mg per week split across those injections, given intramuscularly with a fresh needle and pin each time, rotating sites such as glute, quad or delt. This is general guidance, not medical advice, and cycles are commonly run for 8 to 12 weeks.

Yes. Testosterone aromatises to oestrogen, so many users keep anastrozole or a similar aromatase inhibitor on hand to control oestrogen-driven effects like water retention and gynaecomastia. hCG is also commonly used alongside it to help maintain testicular function during the cycle.

Reported effects include oily skin and acne, raised blood pressure, water retention, hair thinning in those predisposed, and suppression of natural testosterone. Because testosterone shuts down your own production, post cycle therapy is expected, so plan your PCT before you start. Bloodwork before, during and after the cycle covering total and free testosterone, oestradiol, LH, FSH, lipids and liver markers is sensible.

Propionate clears the body in a day or two, so it needs frequent injections, while enanthate has a much longer half-life and only needs dosing once or twice a week. Propionate gives tighter control over blood levels and tends to leave the system faster at the end of a cycle, which is why it is often chosen for shorter runs or to finish one, while enanthate suits longer, steadier cycles with fewer injections.
