Hairloss is genetic. If you are prone to hairloss then the steroids are just going to speed it up / make it worse , but some people can take whatever they want and still have a full head of of hair.
Also Trenbolone is a 19-nor steroid similar to nandrolone and therefore does not convert to di-hydro-testosterone (pretty much the most androgenic steroid there is and number one reason for hairloss) and also has very low androgenic properties itself - in contrast to what a lot of people claim. It is far less androgenic than you'd might think but it certainly does have some very unique effects that usually only very androgenic steroids have (fat-loss , strength gain ..). Common androgenic side-effects such as hairloss , prostate enlargement , acne, virilization (in women) ... usually are very mild when using trenbolone.
I got no idea why it works the way it does (very different from nandrolone) but I never ever haid hairloss problems with trenbolone while on test or drostanolone its very bad.
And also to the permabulkers saying that ZyyzzzzZzz is a twink ... LOL , he is more muscular than 95% of this board ...
