Frequently Asked Questions

How is QSC Testosterone supplied?
QSC Testosterone esters are supplied as ready-to-use oil-based injectable solutions — no reconstitution required. Each vial contains the stated concentration in pharmaceutical-grade carrier oil. Warm the vial briefly in your hand before drawing.
How should injectable Testosterone be stored?
Store at room temperature (15–25°C), away from direct sunlight. Oil-based testosterone solutions are stable for 2–3 years properly stored. Do not refrigerate as this can cause crystallisation of the ester in the oil.
What purity is QSC Testosterone and how is it verified?
QSC Testosterone injectable solutions are ≥99% HPLC pure with MS-confirmed identity on every batch. COA is published on the product page and independently verifiable at verify.janoshik.com.
