Also known as
PhenoSteroid
PhenoSteroid is the alias for Testosterone Phenylpropionate, an injectable anabolic androgenic steroid. It is a short-ester form of testosterone, which means it acts quickly after injection. This page covers the single product available at SynthesisGear: Genetic Labs' 10 ml/100 mg vial. Because of its rapid onset, athletes typically use it to maintain stable blood levels without long gaps between doses.
Product and Dosing
The only listing is the Genetic Labs 10 ml/100 mg vial. The short ester requires frequent administration to keep levels steady, so users report that it must be dosed several times per week. It is an androgenic compound with no additional receptor activity beyond its testosterone profile.
Safety Considerations
As a testosterone derivative, PhenoSteroid carries the standard androgenic risk profile. The short ester means that any side effects appear quickly after dosing. Users should monitor for typical androgenic signs and ensure regular blood work to track liver and lipid parameters. It is not recommended for those under 21.
