Specifically, 2-Androstenone is a pheromone. In vivo, 2-Androstenone reacts as a prohormone would, but because delta-2-androst-17-one is a preexisting metabolite of DHEA and is also found as an Androsterone metabolite on the human skin. Ultimately, it can be called a human pheromone with prohormone like activity. In this case this pheromone converts to another pheromone, 2-androstenol – similar to a non-methylated Phera-Plex.
2-Androstenone, therefore, might be a good replacement for the older boldione compounds. Studies suggest that it is fairly mild with minimal sides and can be run for decent cycle lengths. The main highlight is the increased strength that notably comes from 2-Androstenone.
Basically, Spartan Hard is the wicked awesome love child of Spartan Mass and Spartan Lean.
