TESTOSTERONE CYPIONATE (250 MG)

 Testosterone Cypionate is the backbone androgen used in countless research and clinical models of hypogonadism, performance, and body composition. It’s the reference point for understanding how androgens shape muscle, libido, bone, and metabolic health.

How It Works
Testosterone Cypionate is a long-acting ester of testosterone that slowly releases into circulation after injection. Free testosterone crosses cell membranes, binds androgen receptors, and the receptor–hormone complex then regulates transcription of genes controlling protein synthesis, erythropoiesis, bone formation, sebum production, and sexual function.

Regulatory & Research Note
Testosterone Cypionate is FDA-approved for specific forms of male hypogonadism. Outside those indications and dosing protocols, its use is off-label or non-medical. This product is supplied for research purposes only and is not for human use or self-administration through this site.
