‘Weekend Warrior’ Supplement Contains Undeclared Viagra Relative

The FDA is warning purchasers of Weekend Warrior sexual enhancement dietary supplement to discontinue use and discard the supplement simply because it is adulterated with thiosildenafil, a chemical analogue of the lively ingredient in the erectile dysfunction drug, Viagra® (Pfizer).

The overall health concern expressed by the FDA is that the undeclared drug ingredient may well negatively interact with nitrate drugs for hypertension that act by dilating blood vessels, probably decreasing blood pressure to unsafe ranges.

Weekend Warrior is offered by means of on the web merchants and in some retailers with the promise of “Agility • Vitality • Longevity.” As of this morning, web sites this kind of as Shop4Vitamins are nevertheless marketing the supplement, at a price tag of $ 42.50 for eight tablets.

Supplement makers have been using this tactic since prior to I started teaching pharmacy college students about herbal medicines in 1994, with prescription ED medication or their chemical family members by some means ending up in what are otherwise supposed to be normal supplements. But by including actual medicines to their dietary supplements, they may well actually “work,” but not since of their normal constituents.

In reality, the FDA has been enjoying whack-a-mole with the sexual enhancement supplement sector for years, with this medication wellness fraud web page dedicated to warnings on other equivalent cases.

What does Weekend Warrior purport to be?

The supplement is labeled as containing 500 mg of a proprietary herbal extract and other drugs this kind of as theobromine, a naturally-happening constituent of chocolate that resembles caffeine. Components listed are Tribulus, Cordyceps militaris, Ginger root, Cridimum, Monnier extract, Rhodiola, fenugreek powder, and Avena sativa extract.

I have no idea what “Cridimum” is, but I suspect it is a misspelling of the medicinal plant genus, Cnidium, whose correct spelling seems to be like a misspelling. There’s one particular report in the scientific literature of chemical compounds of Cnidium monnieri having the capacity to unwind rabbit corpus cavernosum, the main blood vessel of the penis.

All method of Cordyceps fungus species have been historically linked to all method of optimistic benefits in Chinese medicine. Large concentrations of chemical substances from the fungus can destroy cancer cells in the laboratory.

Avina sativa? Plain outdated oats. Perhaps it is additional for humor since the use of the supplement is steady with sowing one’s oats.

Troubling Tribulus

Of greatest curiosity, and timing, is the herbal genus, Tribulus – and I assume the makers are referring to Tribulus terrestris. If you Google Tribulus and testosterone, you’ll see the supplement becoming offered on its own with the suggestion that it can boost testosterone concentrations in the physique.

But just this month, a group from Kingston University in London published in the Journal of Dietary Dietary supplements an examination of previously published scientific studies on Tribulus terrestris in animals and human topics.

Regrettably, the scientific studies accessible, which includes one particular patent application, were so varied in doses, research length, and overall design that a proper meta-evaluation of the information was not achievable. But the greatest they could discover is weak evidence that Tribulus extract might enhance testosterone concentrations when in combination with other supplements. The authors do at least note some operate that some dose of the extract can improve release of nitric oxide from blood vessels, an action that would be consistent with an erectile dysfunction item. But by and big, Tribulus sounds trivial.

As for the FDA’s detection of thiosildenafil in Weekend Warrior, we were unable to attain the business for comment. Their site lists no make contact with details and their internet domain, weekendwarriorformen.com is privately registered. We have attempted to contact the business by means of their internet testimonial get in touch with page for comment.
