Decadura 400 by British Pharma
Decadura 400 is the concentrated build of British Pharma’s nandrolone decanoate, dosed at 400 mg per millilitre. Each 10 ml multi-dose vial holds 4,000 mg total, which makes it the choice when injection volume is a constraint or when a research protocol calls for higher weekly doses without piling on millilitres.
Ester profile
- Active: Nandrolone Decanoate USP

Why a 400 mg concentrate
Concentrated builds reduce the oil load per millilitre, which helps in research protocols using multiple compounds in the same syringe. The tradeoff is a heavier carrier system, so smooth injection technique and a fine-gauge pin tend to make a noticeable difference.
