Testo Phen 100 – Testosterone Phenlylpropionate

Testo Phen 100 is testosterone phenylpropionate, an injectable ester of testosterone made by Syncom Labs at 100 mg per ml. Phenylpropionate is a medium-length ester, so it releases testosterone into the bloodstream faster than long esters like enanthate or cypionate but holds longer than propionate. It is used as a base compound to support muscle protein synthesis, strength and recovery.

As a guide only, and not medical advice, beginners commonly run 200 mg per week split into two injections, for example 100 mg on Monday and Thursday, over a 10 to 12 week block. Because the ester is faster acting than enanthate, some users prefer more frequent smaller injections to keep blood levels steady. Always base any dosing decision on bloodwork and a doctor's guidance, not on product copy.

Commonly reported effects include raised blood pressure, acne, hair loss in those already predisposed, and mood changes, so bloodwork before, during and after use is worth doing. Because testosterone suppresses natural production, PCT is required, typically starting two weeks after the last injection with either nolvadex or clomid. Many users also run an aromatase inhibitor such as anastrozole alongside it to keep oestrogen in check, plus hCG to help preserve testicular function.

Phenylpropionate clears faster than enanthate or cypionate, which means blood levels rise and fall more quickly and injections are usually spread over the week rather than once or twice. This can suit users who want tighter control over hormone levels or who are more sensitive to the peaks that come with longer esters. Enanthate and cypionate remain the more common choice for simplicity, since they need fewer injections per week.
