China Warehouse Testosterone Propionate 200mg/mL Injectable | 20-Vial Kit — Short-acting testosterone ester (propionate, ~2-day half-life) — rapid-onset AR agonist studied for acute HPG axis dynamics, androgen pharmacokinetics, and fast-clearance TRT models. ≥99% HPLC purity, MS confirmed, Janoshik COA. Research use only. International shipping: 7–14 days
Testosterone Propionate (Short-acting esterified testosterone (injectable)) is a testosterone propionate ester — C₂₂H₃₂O₃, MW 344.5. The 200mg/mL high-concentration formulation provides a higher dose per mL injection volume. Rapid-onset ester with peak ~24–36h and active window ~2–3 days. Free testosterone activates the androgen receptor (AR). Aromatases to oestradiol via CYP19A1.
Research Applications
High-Concentration Short-Acting Androgen
200mg/mL format reduces injection volume for equivalent dose research protocols
Androgen Receptor Biology
AR binding, nuclear translocation, androgen-responsive gene expression
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
Vesta 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 Vesta Testosterone and how is it verified?
Vesta 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.
Peptide Research Tools: Use Vesta’s free peptide calculators — reconstitution, BAC water, dosing, half-life, and mixing charts.
