Everything in this category is an oil-based preparation supplied in a 10ml multi-dose vial. Concentrations differ by compound — 250mg/ml for testosterone enanthate and Sustanon, 200mg/ml for cypionate, Deca and boldenone, 100mg/ml for propionate, NPP, drostanolone and trenbolone acetate, 50mg/ml for injectable stanozolol — so a 10ml vial holds anywhere from 500mg to 2500mg of active compound depending on which one you are looking at.

Two items sit outside that pattern. Bayer Primoteston Depot is a licensed pharmaceutical product supplied as three prefilled 1ml syringes rather than a vial, and Novartis-Bio Somatropin arrives as ten vials of lyophilised powder requiring reconstitution and refrigeration. Both are listed here with their own presentation details.
