Testosterone Cypionate is a long acting single ester testosterone compound with a half life of approximately 8–12 days, providing stable and predictable blood concentration levels well suited to research protocols requiring infrequent administration. This formulation is manufactured by F40 Biotech and delivers 200mg/mL in a 10mL multi dose vial using MCT (medium chain triglyceride) oil as the carrier base; chosen for its exceptionally low viscosity, clean composition, and well documented tolerability profile.
MCT oil’s ultra low viscosity relative to traditional oil carriers like cottonseed, sesame, and grapeseed oil results in smooth draw and administration characteristics that are particularly appreciated in long duration protocols involving repeated weekly or twice weekly administration. Its clean, refined composition also contributes to excellent injection site tolerability, making it a preferred carrier choice for researchers with sensitivity to heavier oil based formulations. At 200mg/mL this formulation offers a moderate concentration suited to protocols where precise low volume dosing flexibility is a priority.
