Im putting together a transdermal matrix using 4-Androstenediol. The powders that are available to me are in the form of THP ether, propyl carbonate, and methyl carbonate. Which of these 4-AD powders has the highest absorption rate through the skin and works best when turned into a transdermal?
for stacking, which is the safest yet most effective prohormone to stack with 4-AD as a transdermal? i heard 19-nor, to create 19-nor-4-androstenediol, but how strong is 19-nor?
