6-oxo and 1 ad make claim against the risk of increased levels of estrogen. they say that's what makes them different from everybody else. they also claim they actually reduce levels of estrogen, while increase levels of testosterone. do you think their claims are false? thanks again for the feedback.
Of the prohormones available legally, the various andros and dhea for example, most show a much stronger tendency to convert to estrogen than to testosterone or anything that would help gain mass. All have been tested in many studies looking for a hypertrophy or strength gain advantage, and none show it.
So, the prohormones don't seem to help, carry the risk of adverse action (estrogen is non- or anti-anabolic depending on the circumstances), and for what?
Things that increase testosterone or growth hormone or igf-1 are: sleep, very intense work with large muscle groups--squats and dead lifts most famously--possibly zinc, and possibly melatonin. Especially since the latter helps you sleep, which is the most anabolic activity there is other than exercise itself, it seems a better bet. Even for melatonin, caution is advisable, since it is also hormonal in action and therefore has wide systematic effects which we may not fully understand.
hope this helps
