Does oxandrolone supress your HPTA (natural testosterone production)?
Yes. Research shows as little as 2.5mg can supress in some folks. As far as the effects of this lowered test production, at 40mg a day, I would say that it's pretty much split evenly. Half of people will attest to loss of sex drive and testicular shrinkage late cycle, while about half attest that they retained sexual drive without any shrinkage. Bridging users be forewarned.
