Two ingredients are present at doses used in studies. L-arginine, at the two daily servings members are told to take, matches doses that helped. Reviews of trials found 1,500 to 5,000 mg daily improved mild to moderate erection problems more than placebo [1], and a review of fifteen trials in 1000 men found it somewhat useful [2]. Prescription erection drugs worked better than L-arginine alone [3]. Saffron at 30 mg daily improved erections and satisfaction in men with a med-related problems [4], and a 2026 review found saffron helped erectile function [5]. However, a large open study found no real benefit [6]. Ginseng is here at well below the studied dose, though it helped at higher doses [7][8]. Tribulus is also below the studied dose; it beat placebo in some trials [9], but one review called the evidence insufficient [5]. Maca is at a trace dose, and the evidence for it was judged insufficient [5]. Zinc has mixed results, mostly in men on dialysis [10][11]. Diindolylmethane showed no change in erections in one small study [12]. Shilajit, boron and black pepper extract have no human studies for this goal. Animal and cell studies are never counted.

Gentlemen's Desire is a new arrival, and my searches found no product-specific customer reviews. I found none on retailer pages, Trustpilot, Walmart or independent review sites. I can't honestly report themes about this formula's effects, so what follows reflects feedback on Codeage as a brand. That feedback is not specific to this product, and you should read it that way. On Trustpilot, reviewers overwhelmingly had a great experience with Codeage across about 850 reviews. Customers often praise supplement quality and say they notice improvements in their daily wellness routines. They also like the fast shipping and the responsive customer support. A Walmart reviewer of another Codeage product called the quality superb. They said they like that the herbal supplements are organic and that they work. They planned to buy the men's multivitamin for an active older husband, which suggests customers trust the brand for men's health. The recurring complaints are logistical and not about the formulas. Some customers report shipping delays, lost packages and incomplete orders. A few had trouble tracking shipments or getting prompt answers from customer service. Reviews.io shows a similar split. Many people describe reliable, fast delivery. Others say orders took 7 to 10 business days or longer, even with paid expedited shipping. For this product, expect the usual caveats for libido supplements. Results vary from person to person, and effects from herbal blends like maca, shilajit and ginseng usually build over weeks. Check for real buyer reviews on codeage.com, Amazon and other retailers as they appear.

Biohacker Summary

Members Only10 of 10 recommend it
10 of 10 biohackers on our panel recommend it

Zinc is the main ingredient, and all ten panelists spoke about it, with most recommending it or using it. They take it for testosterone and sperm health, immune support, wound healing, mood, and gut lining, and one takes 15 mg each morning for longevity. Doses mentioned include 30 mg for sperm health, 40 to 60 mg a day for fighting viruses, and a surgery protocol before and after an operation; forms mentioned include zinc carnosine for the gut, and it was paired with vitamin C for immunity and with magnesium for sleep. One panelist noted that zinc raises testosterone only when zinc or testosterone levels are low, and another noted that birth control pills deplete zinc. Saffron, mainly for mood, is a smaller ingredient in this product and drew recommendations from several panelists, while another smaller ingredient, Tribulus terrestris, drew a warning that it will not raise testosterone.

RAL Summary

Members OnlyTier 4 for Sexual Health for Men

The 1110 reviews counted are brand-level feedback about Codeage on sites like Trustpilot, not reviews of Gentlemen's Desire, since our own review search found no product-specific reviews. Its reviews are set aside, so it is graded on its studies alone. Human studies support Zinc (7 of 22 human studies showed an improvement), but there are not yet enough reviews to confirm it (0).

Take 2 servings a day (6 capsules) to match the dose that worked in the studies.

  • Emerging: not enough evidence to rank higher yet.

Where the evidence disagrees: 21 of the 84 human studies found no effect.

Body systems: Reproductive system, Cardiovascular system, Endocrine system

Combine with: For men, this product pairs well with L-citrulline or L-arginine for nitric oxide and blood flow, Panax ginseng for erectile support and energy, Tribulus or fenugreek for libido, zinc and magnesium for testosterone support, and ashwagandha to reduce stress-related performance issues. Women seeking sexual function support would be better served by a women-specific formula, such as one with Maca, Tribulus, saffron, ginseng, L-arginine, or ashwagandha for arousal and libido, plus hormone-balancing nutrients such as vitamin D, B vitamins and magnesium. Consult a healthcare provider before combining supplements, especially with blood pressure, nitrate or hormone-sensitive medications.

Possible side effects: L-arginine caused mild side effects in 8.3% of men versus 2.3% on placebo in pooled trials; Tribulus was well tolerated with no more side effects than placebo.
