What is Primo Enanthate
Metenolone attached to an enanthate ester. Release is steady, so levels stay calm with split weekly shots.
How long it stays in your system
With a 7–10 day half-life, activity persists for roughly two to three weeks after the last shot. Plan PCT with this clearance.
Dosing principles
Primo rewards patience, clean food, and logbook discipline. Lean conditions amplify the cosmetic return per milligram.
