Dose on a U-100 syringe

What it does
Masteron enanthate does the same job as the propionate version but on a longer ester, so twice-weekly injections work. It takes a few weeks to reach full effect, which makes it better suited to longer blocks than short pre-contest runs.
Mechanism
DHT-derived androgen receptor agonist with mild aromatase inhibiting activity. Non-aromatizing.
