Yohimbine
Yohimbe bark extract / yohimbine HCl · Metabolic
A stimulant alpha-2 blocker with a real but narrow fat-loss and erectile-function record and a rough side-effect profile.
What the evidence says
One athlete trial showed fat loss; erectile function trials are older and modest. The stimulant side effects are well documented.
What studies used
Trials commonly use 0.2 mg per kg bodyweight; labels list 2.5-10 mg per serving.. Fasted before cardio, per the fat-loss studies..
Reported from published studies and product labelling — a record of what was used in research, not a recommendation. What is right for you is a conversation with a clinician.
Watch out for
- Anxiety, racing heart, blood pressure spikes
- Antidepressants, blood pressure drugs, stimulants
- Bark extracts vary; standardized yohimbine HCl is more predictable
