What is NPP 200mg/mL (Nandrolone Phenylpropionate)?
Nandrolone Phenylpropionate 200mg/mL (High-concentration short-acting 19-nor AAS (injectable)) is the phenylpropionate ester of nandrolone — C₂₇H₃₄O₃, MW 406.6. The 200mg/mL formulation doubles the dose per mL vs 100mg/mL, reducing injection volume for equivalent dose protocols. Short-acting ester (peak ~1–2 days, active ~5–7 days). High anabolic/low androgenic ratio. Activates progesterone receptor. Partial aromatisation (~20% of testosterone rate).

Frequently Asked Questions
How do I reconstitute this peptide?
QSC injectable solutions are supplied ready-to-use — no reconstitution required. Each vial contains the stated concentration in pharmaceutical-grade carrier (oil or aqueous). Draw using a sterile syringe appropriate for the solution viscosity.
How should this peptide be stored?
Oil-based solutions: store at room temperature (15–25°C), away from direct sunlight — do not refrigerate as cold temperatures can cause crystallisation. Aqueous solutions: store at 2–8°C. Properly stored, injectable solutions are stable for 2–3 years.
What purity is this QSC compound and how is it verified?
All QSC injectable compounds are ≥99% pure by HPLC on every production batch, with MS-confirmed identity. COA is published on the product page and independently verifiable at verify.janoshik.com.
