What is Testosterone Propionate?

Testosterone Propionate (Short-acting esterified testosterone (injectable)) is a testosterone propionate ester — C₂₂H₃₂O₃, MW 344.5. Shortest-chain testosterone ester providing rapid onset (peak ~24–36h, active ~2–3 days). Requires more frequent administration than longer esters. Free testosterone activates the androgen receptor (AR). Aromatases to oestradiol via CYP19A1.

Research Applications

Short-Acting Androgen Models

Rapid-onset testosterone delivery for acute AR activation studies

Androgen Receptor Biology

Pharmacokinetic Research

Short half-life enables precise peak-and-trough testosterone studies

Aromatisation Research

CYP19A1 conversion to oestradiol — oestrogenic co-effects

HPG Axis Research

Rapid suppression/recovery kinetics of the hypothalamic-pituitary-gonadal axis

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.
