What did @dr.yerayraiz actually say?
Honestly, this is where things get complicated. The transcript provided for this video is incoherent, a string of fragmented English phrases mixed with brief Spanish that does not form a legible argument. The video is categorized under TRT and testosterone optimization, and the caption promotes "bitters de guanábana" (soursop bitters) via an Amazon affiliate link. So the implied claim, even if never stated clearly on camera, is that soursop bitters offer some hormone or health benefit worth buying.
We cannot quote a specific claim because no specific claim was captured coherently. What we can evaluate is the product being pushed, the platform context, and what the science says about soursop and testosterone. That is what this fact-check is actually doing.
Does the science back up soursop as a testosterone booster?
Short answer: not in any meaningful clinical sense. There is preliminary animal data, but nothing that would justify marketing this to men interested in hormone optimization.
Soursop (Annona muricata) has been studied primarily for its antioxidant and anti-inflammatory properties, not for androgenic effects. One study by Moghadamtousi et al. (2015, Scientific World Journal) reviewed its bioactive compounds, including acetogenins and alkaloids, and found anti-tumor and antioxidant activity in cell and animal models. None of this translates to testosterone support in humans.
A rodent study published by Ezeagu et al. (2019, Journal of Dietary Supplements) looked at soursop leaf extracts and male fertility markers in rats. Some parameters improved slightly. But rat studies on herbal extracts routinely fail to replicate in human trials, and this particular extract is not soursop bitters sold on Amazon. Dosing, preparation, and bioavailability are entirely different variables.
There are no peer-reviewed human clinical trials establishing soursop as a testosterone booster. Full stop.
What did they get wrong, or right?
Because the transcript does not contain a legible claim, we cannot credit or discredit a specific statement. What we can say plainly is this: pairing a TRT category tag with an affiliate link for an unstudied herbal product is misleading framing, regardless of what was said on camera.
Soursop has genuine antioxidant properties. That part is real science. Moghadamtousi et al. (2015) and other researchers have documented legitimate bioactive compounds in the plant. If the video simply said "soursop has antioxidants," that would be defensible.
But placing this content in a testosterone optimization category, where men are often actively managing hypogonadism or considering hormone therapy, implies a hormonal benefit that does not exist in the evidence base. That framing does real harm. Men who are genuinely hypogonadal need clinical evaluation, not Amazon bitters.
There is also a safety note worth flagging. Annona muricata at high doses has shown hepatotoxic effects in animal models (Okolie et al., 2013, African Journal of Pharmacy and Pharmacology). "Natural" does not mean risk-free, especially in concentrated bitter extracts.
What should you actually know?
If you are watching content tagged under men's health and TRT, you deserve to know when a product has no clinical backing for the implied benefit.
Soursop is a fruit with a real nutritional profile: vitamin C, B vitamins, fiber, and documented antioxidant compounds. Eating the fruit or drinking a reasonable quantity of a soursop-based beverage is unlikely to harm you. But buying "bitters" from an Amazon affiliate link because a social media video implied it helps your hormones is a different proposition entirely.
Testosterone deficiency is a clinical condition diagnosed via blood work and assessed against symptoms. The clinical threshold for treatment typically involves total testosterone below 300 ng/dL alongside symptoms, per Endocrine Society guidelines (Bhasin et al., 2018, Journal of Clinical Endocrinology and Metabolism). No herbal bitter corrects that. If you suspect low testosterone, get a morning serum test from a licensed provider, not a supplement.
Affiliate-linked health content on Instagram is not a substitute for clinical evaluation. The 22,500 people who watched this video deserve that clarification.
