Dose on a U-100 syringe

What it does

Boldenone is a slow compound - most users need 16 weeks or more to see the payoff. It is usually reported as lean, dry gains with a big appetite bump, which some people love and others hate. Its main watch point is a steep rise in red blood cell count.

Mechanism

Testosterone derivative with a double bond that reduces androgenic activity. Aromatizes at roughly half the rate of testosterone. Strongly stimulates erythropoiesis, raising hematocrit.
