stimulatory effects are not as strong but they are more even. with oral yohimbine intake spike is very quick and yohimbine is metabolised VERY quickly- half life is 7-11min.
with topical admin you get a slower release- resulting in less stimulation (as compared to dose- though one can typically take/tolerate a lot more) though a much more even stimulatory effect.
btw- with oral intake time till uptake is generally longer than dermal route 30-45min as opposed to 20-30min.
oral bioavailability varies 7-87% this can be increased by sublingual admin- though this will speed yohimbine into blood stream.
Yohimbine WILL get rid of FATTY TISSUE GYNO- estrogenic fat around the nipple and under the nipple.
Whether it will help with hard tissue is unclear, though some have reported reduction in hard tissue- whether this is directly attributable to yohimbine ???
