Testosterone Combo

Four testosterone esters in one 250 mg/ml solution — propionate 30 mg, phenylpropionate 60 mg, isocaproate 60 mg and decanoate 100 mg. Their chain lengths span short to long, so a single injection delivers testosterone in overlapping waves: the propionate gives an early rise within a day or two, while the decanoate carries the tail out past a week. It is the classic sustained-release testosterone profile, from one ampoule.

Filled at concentration into an oil carrier with a benzyl benzoate co-solvent, sterile-filtered and nitrogen-overlaid, ten ampoules to a serialised carton — the very testosterone we hold as the reference for this site's pack-verification demonstration.
