Three long-estered androgens share a single vial here: trenbolone enanthate, testosterone enanthate and drostanolone enanthate, blended to a combined 300 mg per millilitre in a 10 ml multidose vial from Dragon Pharma.
All three carry oil-soluble esters, so the preparation releases slowly after injection instead of clearing within a day. The appeal of a fixed blend is that one draw covers a testosterone base, a 19-nortestosterone derivative and a DHT-derived compound without keeping three separate vials on the shelf. Dragon Pharma builds a large part of its injectable range around ready-made combinations of this kind.
