not similar to yohimburn.
1. it contains DMSO, which is illegal, and also means a greater uptake systemically and not locally
2. all the reports on this product indicate that it turns the users skin orange and of the few people that have used a high percentage seem to experience rashes.
3. freebase yohimbine is notoriously unstable
4. octopamine has been shown to be inneffective in humans
5. it contains the pro-hormone 6-oxo whose physiological effects are dubious at best and the mechanism of action unknown to it creator- it was supposedly an aromatase inhibitor, but now seems to claim its a SERM.
6. the precursor to formestane is OK. but since no amounts listed??
actually no amounts listed for any of the ingredients.
