Preparations of this category are characterised by activity similar to that of nandrolone, which is believed to be a nearly perfect steroid when used in reasonable amounts. Nandrolone derivatives are fantastic as base supplements during cycles aimed at increasing muscle mass, as they show strong affinity with androgenic receptors. Moreover, because they do not bind with SHBG, they have a much more powerful ability to initiate muscle tissue synthesis than testosterone.
For supplementation of preparations containing nandrolone derivatives to make sense and bring expected results, it must be supported by intensive strength training and a properly adjusted diet rich with protein of animal origin. When taking prohormones, you must make sure you are aware of their activity and possible side effects.
