What is Boldenone Undecylenate (EQ)?
Boldenone Undecylenate (Equipoise/EQ) is a testosterone derivative with a C1-2 double bond reducing androgenic potency and aromatisation. Long-acting undecylenate ester. Studied for erythropoiesis (EPO upregulation), anabolic activity with reduced androgenicity, and comparative steroid pharmacology. Research use only.
Research Applications
Erythropoiesis Research
EPO upregulation, haematocrit increase, reticulocyte count — boldenone-specific effect
Reduced Aromatisation
C1-2 double bond aromatase-resistance — lower estradiol conversion than testosterone
Long-Ester Undecylenate PK
Undecylenate ester hydrolysis, extended release — longest common testosterone ester
Comparative AAS Pharmacology
Boldenone vs testosterone — C1-2 double bond effect on receptor binding, tissue activity
Anabolic:Androgenic Ratio
Intermediate A:A ratio — anabolic selectivity profiling
