What is Sustanon Blend?
Sustanon is a blended-ester testosterone raw powder mixture combining four distinct testosterone esters — Propionate, Phenylpropionate, Isocaproate, and Decanoate — in the classic 30:60:60:100 weight-ratio formulation. The staggered ester-chain lengths (short, medium-short, medium, and long) are designed to produce sequential hydrolysis and a blended, layered release-kinetic profile rather than the single-phase kinetics of any one ester alone. Research tool for comparative esterase hydrolysis-rate studies, multi-compartment pharmacokinetic modeling, and blended-release-profile research across the androgen ester family. 1KG bulk blend for large-scale research programs. Research use only.
