What is DHB (1-Test Cypionate / Dihydroboldenone Cypionate) 100mg/mL?
DHB (Dihydroboldenone Cypionate, also known as 1-Testosterone Cypionate) is the cypionate ester of 5α-reduced boldenone — a non-aromatising anabolic steroid with high intrinsic androgen receptor binding affinity. Unlike testosterone, DHB is not a substrate for aromatase, eliminating estrogen conversion. The cypionate ester provides ~7–10 day active duration. Research tool for non-aromatising long-ester AAS pharmacology and comparative boldenone/DHB studies. Research use only.
