TRT Gummies (Boost TRT, Primo): What’s in Them

Disclosure: PrescribedRX sells its own treatments, so we compete with some of the companies covered here, and we may earn affiliate commissions.

Short answer: “TRT gummies” such as Boost TRT and Primo TRT are not testosterone replacement therapy. They are sold as gummy supplements, and Primo TRT’s launch announcement says “Primo TRT is not a medication” (Primo TRT press release). Rather than repeat Boost TRT reviews, this page reports what the brands list: pages presenting themselves as each brand’s official site in October 2026 list different ingredients and publish no amounts. Where a testosterone study exists for a listed ingredient, the results cited below are mixed, and a 2021 review found the most supportive data, for fenugreek and ashwagandha, in small trials (Smith 2021).

Everything below about each brand is as listed on the named page on October 17, 2026. Brand claims are quoted as theirs. We did not buy or test either product.

Are TRT gummies actually TRT?

No. TRT, testosterone replacement therapy, means prescribed testosterone, which our testosterone treatment hub and TRT guide describe. Gummies with “TRT” in the name are labeled and sold as supplements.

Primo TRT’s own launch announcement says “the company insists that Primo TRT is not a medication” (Primo TRT press release).

What is Boost TRT, and what does it list?

The page at us-boost-trt.com does not name a manufacturer or a company address. It calls itself the “USA Official Website” for “BoostTRT Male Enhancement Gummies”. As listed there in October 2026 (us-boost-trt.com):

• Ingredients named: L-Arginine, Muira Puama Extract, Asian Red Ginger Extract, Saw Palmetto Berry, Ginkgo Biloba Extract and Horny Goat Weed Extract. No amounts are given.
• Price shown: “Only for: $39.97/each”, with a “Regular Price” of $66.23.

What is Primo TRT, and what does it list?

Two sources that speak for Primo TRT list different ingredients. The press release names a third domain, primotrt.com, as the official site.

The August 26, 2025 press release

A paid press release distributed by GlobeNewswire describes Primo TRT as a Los Angeles-based company and lists ashwagandha, D-aspartic acid, fenugreek extract, vitamin D3, Tribulus terrestris, zinc, maca root, and vitamins B6 and B12. It gives no amounts and tells readers to check the packaging or primotrt.com for dosage. The release also says ashwagandha has been shown to raise testosterone “by up to 14.7 percent within eight weeks” and that D-aspartic acid “could raise testosterone by up to 42 percent”, without naming a study for the second figure (Primo TRT press release).

The primo-trt.us “official site”

The page at primo-trt.us is titled “Primo TRT OFFICIAL SITE”. It names the primary ingredients as apple cider vinegar, vitamin B12, folic acid, organic cane sugar and pectin, and separately mentions shilajit. It gives no amounts, lists a suggested dose of “two gummies daily”, and shows “$49/Bottle”. Its footer says “we may be paid a fee by the merchant” (primo-trt.us).

What do studies report for each ingredient?

Ashwagandha. In a 16-week crossover trial of 57 overweight men aged 40 to 70, eight weeks of an ashwagandha extract was associated with a 14.7% greater increase in salivary testosterone than placebo. The authors found no significant differences in fatigue, vigor or sexual well-being (Lopresti 2019). The press release’s 14.7% figure matches this trial’s salivary testosterone result.

Fenugreek. A meta-analysis that pooled four randomized trials reported a significant effect of fenugreek extract on total testosterone (Mansoori 2020). A systematic review of 32 herbal trials named fenugreek seed and ashwagandha extracts as the two with positive effects, while noting small samples and that only 6 of 32 studies had a low risk of bias (Smith 2021).

D-aspartic acid. In 24 resistance-trained men, 6 g a day for 14 days lowered total and free testosterone, and 3 g a day had no significant effect (Melville 2015). A systematic review found four human studies with inconsistent results (Roshanzamir 2017).

Tribulus terrestris. In 21 young men given tribulus extract or placebo for four weeks, researchers found no significant difference in testosterone, androstenedione or LH (Neychev 2005).

Maca. In a 12-week randomized trial in men aged 21 to 56, sexual desire scores improved from week 8, but serum testosterone and estradiol were not different from placebo (Gonzales 2002).

Vitamin D. In 54 overweight men who started with low vitamin D, total testosterone rose from 10.7 to 13.4 nmol/L over one year of vitamin D, with no change on placebo (Pilz 2011). In 98 healthy men with normal testosterone, 12 weeks of vitamin D had no effect on total testosterone (Lerchbaum 2017).

Zinc. One small study reported that testosterone fell in four young men put on a zinc-restricted diet, and rose from 8.3 to 16.0 nmol/L in nine marginally zinc-deficient older men given zinc for six months (Prasad 1996).

Shilajit. A 2024 systematic review rated one purified, branded shilajit extract (PrimaVie) “possibly effective” for men with late-onset hypogonadism (Morgado 2024). The primo-trt.us page does not name an extract or amount.

The other ingredients. Testosterone studies of L-arginine, muira puama, red ginger, saw palmetto, ginkgo, horny goat weed, apple cider vinegar, B vitamins and folic acid are not reviewed here. Our guide to testosterone booster ingredients covers the wider category.

What do reviews of “testosterone boosters” conclude?

A study of 50 “T booster” supplements found that 90% claimed to boost testosterone. The products contained 109 unique ingredients. Searching PubMed, the authors found data showing an increase in testosterone for 24.8%, a decrease for 10.1% and no change for 18.3%, and no data for 61.5%. Thirteen products exceeded the upper intake level for zinc, vitamin B3 or magnesium (Clemesha 2020).

A 2024 systematic review of 52 studies covering 27 proposed boosters concluded that most fail to increase total testosterone (Morgado 2024). For how supplements compare with prescribed testosterone, see TRT vs testosterone boosters.

When should you talk to a doctor?

Talk to a licensed provider before starting any supplement, especially if you have diabetes, high blood pressure, high cholesterol or heart disease, or take other medicines. Tell your doctor about every supplement you take. If you have symptoms you think are low testosterone, see signs of low testosterone and talk to a licensed provider. For a medical emergency, call 911.

How can you check your testosterone?

A supplement label can’t tell you your testosterone level; a blood test can. The $69 hormone panel offered through PrescribedRX covers total testosterone, LH, hematocrit and PSA, drawn at a Quest lab near you, and a licensed provider reads the results. Our page on normal testosterone levels explains the ranges. A licensed provider decides whether treatment is appropriate for you. Testosterone treatment offered through PrescribedRX is compounded testosterone cypionate, and plans are $387 every 3 months. Compounded medications are prepared by licensed pharmacies and are not FDA-approved. See TRT cost for how pricing compares.

Start with the $69 hormone panel, or browse testosterone treatments. Self-pay, no insurance, and availability varies by state; the eligibility check confirms yours.
