Pharmacology
IndicationNot Available
PharmacodynamicsThe activity of boldenone is mainly anabolic, with a low androgenic potency. The drug is commonly used in doping within bodybuilding, even though this use is illegal. If intended to assist in bodybuilding, the drug is taken as part of a steroid stack of other anabolic steroids, usually with a potent androgen like testosterone as the 'base' of the stack. Boldenone is an androgen that differs from 17b-testosterone (17b-T) by only one double bond at the 1-position, and the removal of the methyl group protecting the 17-OH group allows it to be orally active.
Mechanism of actionBoldenone is a steroid hormone which has androgenic activity. Androgens bind to the androgen receptor, which regulates gene transcription.

General Function:
Zinc ion binding
Specific Function:
Steroid hormone receptors are ligand-activated transcription factors that regulate eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Transcription factor activity is modulated by bound coactivator and corepressor proteins. Transcription activation is down-regulated by NR0B2. Activated, but not phosphorylated, by HIPK3 and ZIPK/DAPK3.
