Tried yohimbine last night

[guyver]

i used V and C, both are great!! cialis last alot longer, but my body got used to it, have not used in about 2 months, i used yohimbe standardized at 18mg and got better wood than V or C, but just the first 2 times i used, now not so much, wonder if i should take the yohimbine hcl at more than 18mg? been looking at dostinex or bromo, where can i get it, and which would be better?
