The World Anti-Doping Agency (WADA) prohibits all athletes from taking any drugs or supplements that include higenamine which may have harmful effects on the heart.

John Travis, a senior research scientist at NSF International have revealed that higenamine is a widely used supplement ingredient, and companies that produce such supplements do not properly list the dosage.
“We’re urging competitive and amateur athletes, as well as general consumers, to think twice before consuming a product that contains higenamine.”
“Beyond the doping risk for athletes,” he adds, “some of these products contain extremely high doses of a stimulant with unknown safety and potential cardiovascular risks when consumed.”

“What we’ve learned from the study is that there is often no way for a consumer to know how much higenamine is actually in the product they are taking.
The researchers analyzed 24 supplements for weight loss or preworkout that listed higenamine, also known as norcoclaurine and demethylcoclaurine.
The 24 products tested in the study were: Adrenal Pump, Apidren, Beta-Stim, Burn-HC, Defcon1 Second Strike, Diablo, DyNO, Gnar Pump, Higenamine, High Definition, HyperMax, iBurn2, Liporidex Max, Liporidex PLUS, LipoRUSH DS2, N.O. Vate, OxyShred, Prostun-Advanced Thermogenic, Pyroxamine, Razor8, Ritual, Stim Shot, ThermoVate, and Uplift.
Only five products mentioned an exact quantity of higenamine. But, when the supplements were tested, the researchers discovered that the listed quantities were improper.
Actual quantities of higenamine across the range of products included anything from trace amounts to 62 milligrams per serving. However, based on the label instructions, users may actually take up to 110 milligrams of the substance per day, which may be detrimental to their health.

“Some plants, such as ephedra, contain stimulants. If you take too much of the stimulants found in ephedra, it can have life-threatening consequences,” explains study.
“Similarly, higenamine is a stimulant found in plants. When it comes to higenamine, we don’t yet know for certain what effect high dosages will have in the human body, but a series of preliminary studies suggest that it might have profound effects on the heart and other organs.”
