What is 1-Testosterone Cypionate (DHB)?
1-Testosterone Cypionate (DHB — Dihydroboldenone) is the cypionate ester of 5α-reduced boldenone. High intrinsic AR binding affinity, no aromatisation. The cypionate ester provides extended release (~7–10 days). Research tool for non-aromatising long-ester AAS pharmacology and comparative boldenone/DHB studies. Research use only.
Research Applications
Non-Aromatising Long-Ester AAS
DHB cypionate PK — sustained non-estrogenic androgen exposure
Boldenone vs DHB
5α-reduction impact: boldenone vs dihydroboldenone potency, receptor binding
High AR Affinity Research
DHB AR binding relative to testosterone and DHT — intrinsic potency
Ester Release Research
Cypionate ester hydrolysis of DHB vs testosterone cypionate — comparative PK
