Ten ampoules, a millilitre apiece, 100 mg of methenolone enanthate in each - this is Dragon Pharma's version of the injectable depot form. The carton carries a verification code that can be checked against the company's own database, a practice that has become fairly standard among the larger labs.
The enanthate ester slows release of methenolone from the injection site over a matter of days. That is the whole difference between this and the acetate preparations: same active molecule, a longer delivery curve, and injections spaced correspondingly further apart.
