Yohimibine is an alkaloid derived from the bark of Pausinystalia yohimbe, an evergreen tree that grows in several tropical west African countries, including Gabon, Congo, Cameroon and Nigeria.
Traditionally, yohimbe bark has been used in west Africa as a general tonic, a performance enhancer for athletes and an aphrodisiac.
The alkaloid yohimbine has been used in veterinary medicine to reverse sedation in deer and dogs.
While yohimbine HCL was previously prescribed for erectile dysfunction, it has been replaced with more effective modern medications.
Most of the research on this supplement has focused on its benefits for sexual performance. However, the majority of user reviews of Primaforce Yohimbine HCL demonstrate that this supplement is more commonly taken to promote weight loss.
Primaforce Yohimbine HCL is one of several yohimbine supplements available over the counter in the United States. It is available for $10 per bottle and each bottle contains 90 capsules.
Studying Yohimbine’s Effects
Researchers from the Institute of Sports Medicine performed a clinical study to determine the effects of yohimbine on exercise performance and body composition of professional soccer players.
Twenty top-level male players took part in two randomly assigned trials; one group took 20 mg of yohimbine per day in two equal doses, the other received a placebo.
The yohimbine group experienced a significant decrease in body fat. However, there was no difference in exercise performance between the yohimbine and placebo groups. Neither group reported side effects.

How to Take Primaforce Yohimbine HCL
The recommended dosage of Primaforce Yohimbine HCL depends on the desired effect. Each capsule contains 2.5 milligrams yohimbine.
Many reviewers using Primaforce Yohimbine HCL report taking several doses throughout the day instead of a single dose at one time. In studies of yohimbine’s effects, the following dosages were used:
- For athletic performance, 20 mg yohimbine HCL was taken twice daily for 21 days.
- For anxiety, 10 mg yohimbine HCL was taken once a week 45 minutes before undergoing exposure therapy. In another study involving fear conditioning, 20 mg yohimbine HCL was taken thirty minutes before therapy./
- For erectile disfunction, participants took a range of 1 to 100 mg yohimbine HCL daily divided into doses two to four hours before sexual activity.
- For fat-burning, the recommended dose is .2 mg for every kilogram of body weight. An effective dose for a 200 pound man would be 18 mg.
Data for other uses is currently incomplete. Yohimbine is not recommended for use by children, people with heart disease or people who suffer from anxiety.
Primaforce Yohimbine HCL Side Effects
Primaforce Yohimbine HCL can cause adverse effects if it is used improperly or taken by individuals with a high sensitivity to stimulants.
A number of side effects and adverse effects have been associated with yohimbine when taken at higher than recommended doses.
According to Memorial Sloan Kettering Cancer Center, yohimbine can cause high blood pressure, anxiety, nausea, nervousness, dizziness, rapid or irregular heartbeat, sleeplessness, urinary problems, psychiatric symptoms and diarrhea.
Sloan Kettering goes on to observe more severe side effects in a handful of case reports:
- Two unrelated deaths have been attributed to yohimbine overdoses.
- A 39-year-old body builder experienced acute neurotoxic effects that included vomiting, malaise, loss of consciousness and repeated seizures. The symptoms abated 12 hours after treatment.
- A 42-year-old man, after taking yohimbine for impotence, experienced kidney failure, skin eruptions and lupus-like symptoms. Because these symptoms were not present before taking yohimbine, doctors attributed them to the supplement.
- A 42-year-old man experienced severe pain and a persistent erection requiring surgery.
A review of adverse drug events (ADEs) reported to the California Poison Control System (CPCS) explored 238 cases in which side effects of Yohimbine were reported between 2000 and 2006.
98.7% of cases involved users taking yohimbine supplements, as opposed to the prescription drug. The common reasons for use included weight loss, stimulant effects and sexual enhancement.
Common adverse events reported included elevated heart rate, gastrointestinal distress, hypertension, anxiety and agitation.
Yohimbine exposures were more likely to require treatment at a healthcare facility than the average substance exposure reported to CPCS. Researchers saw a substantial increase in the prevalence of adverse events with yohimbine over the seven-year period studied.
