What is BLEND 500 (Trenbolone Enanthate 250mg + Drostanolone Enanthate 250mg)?
BLEND 500 is a high-concentration dual long-ester research preparation combining Trenbolone Enanthate 250mg/mL and Drostanolone Enanthate 250mg/mL. Both compounds share the enanthate ester for aligned release kinetics. Total concentration of 500mg/mL allows high-dose research protocols in minimal injection volume. Research use only.

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.
