i used ergopharm 1 AD and lost some hair...my scalp became inflamed and tight while on it,,,great gains though,,,but never again will i use a 1- testosterone product....i currently am on ergopharm nordiol at 900 mg a day(on day 6 so far) no inflamed scalp,,,,,yet no pumps or gain in muscle,,,( $46 wasted) i tried norandrostenedione with beter results even though it is said that the diol version has a higher conversion rate,,,,,,the dione version made me loose hair though....be carefull with the 1-testosterone though
