Boldeprime is Eminence Labs' entry in the boldenone line, filled at 200 mg per millilitre, ten ampoules to the box — a middle concentration, thinner in the barrel than the 300 and 500 mg solutions other labs put out.
Boldenone is an anabolic androgenic steroid — testosterone with an extra double bond in the A ring — and it reached the market first in veterinary medicine. The undecylenate ester on it is long-chain, so the compound leaves the injection site over days rather than hours, which puts injections far apart.
Oil-based intramuscular solution; glass ampoules mean a single opening and no stopper to reuse.
