Boldenone Undecylenate

Boldenone is Δ1-testosterone — testosterone with an extra double bond that tempers its androgenic character and blunts aromatisation. Paired with the eleven-carbon undecylenate ester, one of the longest we handle, it leaves the depot gradually over weeks, giving one of the flattest, smoothest plasma curves in the register.

At 250 mg/ml the solution is concentrated, so it is built on an oil carrier with a benzyl benzoate co-solvent, sterile-filtered and nitrogen-overlaid to guard against oxidation. Ten 1 ml amber ampoules per serialised carton; store at room temperature, away from light.
