Study, Trial or Testing Result Summary
Members Only84 human studies · 51 improved
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.

Members Only1,100 reviews · 95% positive
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
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.

Ben Greenfield · Zinc · warns
- Ben Greenfield's formulation includes 30 grams of zinc a day, taken for one week before surgery and two weeks after, as it is an important cofactor for wound healing.
- Advises patients to stop ginseng before surgery because it can act as a med or antiplatelet agent.
- Emphasizes that zinc sufficiency is crucial for immunity because the thymus-derived peptide thymulin, which trains lymphocytes, requires zinc to be active.
- Mentions an arginine link to thymus metabolism, noting that immune cells require a lot of arginine.
- Recommends adding zinc into one's stack because it is a co-factor for enzymes involved in testosterone synthesis and sperm maturation, and zinc deficiency is a reproducible cause of low sperm count.
- He mentions zinc as a supplement with real human data behind it for male fertility.
- Recommends Shilajit, mentioning Organifi gummies, for its antioxidant and mineral chelating properties, citing human trials showing increases in sperm count, motility, and testosterone.
- He mentions shilajit as a supplement with real human data behind it for male fertility.
