Sealed glass ampoules, ten to the carton, each holding 1 ml at 250 mg/ml — this is the most concentrated single-ester trenbolone in Alpha Pharma's catalogue, and the ester is enanthate.
Enanthate is the long-acting option: its seven-carbon chain slows release substantially, placing anything built on it at the infrequent end of the injectable range. Packing 250 mg into a single millilitre makes for a fairly dense solution, which is normal for high-strength oil preparations. The ampoules ship in a pharmaceutical-style carton with a scratch-off verification code.
