It possibly could....think Helios (clenbuterol/yohimbine combo) considering the molecular weight of
ephedrine is less than
clen and could possibly be absorbed through the dermis. Although the actual effects seen might be a disappointment. Also, this is a novel thought because (I believe, but not 100%) then it would be legal again to buy
ephedrine since it is not for consumption. Of course, what is to stop us from ingesting the formula....granted its not mixed in DMSO.
