METHYLAND ROSTENENDIOL ­ METHANDRIOL (PROTOBOL)

This is in fact one of the first design of prohormones. Protobol (17a-methyl-5a-androst-17b-ol) one of the best with minimal side effects, and weight averages growth. Related to Epistane and Halodrol, but with a somewhat lesser effect. Protobol converted to methyl-dihydrotestosterone (mestanolone). Mestanolone primarily androgenic.
