Thorne Advanced Testosterone Support Review

Advanced Testosterone Support is a capsule formula from Thorne designed to support the body's natural production of testosterone. The page explains that healthy testosterone levels are associated with several health benefits, including optimal sexual function, muscle health, healthy libido, and vitality. Thorne presents the product as a way to help men maintain mental and physical vigor. The page lists benefits such as maintaining a healthy body composition and lean body mass, healthy libido and sexual function, reduced muscle fatigue to make workouts more productive, improved endothelial function to support blood flow throughout the body, and optimal mental performance and positive mood. The page notes that testosterone levels start dropping naturally at about 1-2% a year in men between ages 30 and 40, and that total testosterone has declined over the past two decades, even among young men. It also lists common causes of low testosterone in men, including the natural aging process, overweight or obesity, stress, testing later in the day, medical conditions such as diabetes, kidney, and liver disease, and medications including meds, meds, meds, and opiates. The formula's key ingredients are shilajit extract at 500mg, luteolin phytosome at 150mg, ashwagandha extract from root and leaf at 120mg, and zinc as zinc bisglycinate chelate at 15mg. The serving size is 2 capsules and there are 30 servings per container. Shilajit is described as decomposed plant matter fermented by soil organisms, supplied as the trademarked PrimaVie ingredient, and said to contain urolithins, humic acids and minerals. Shoden ashwagandha is described as a high-potency extract containing 35% withanolide glycosides. Luteolin is described as a flavonoid with a structure similar to sex hormones, supporting a healthy ratio of testosterone to estrogen, and the phytosome form is said to enhance absorption. The zinc is described as bound to glycine for absorption and linked to testosterone and sperm production. The page states the product has a fully transparent label, uses purest possible ingredients in highly absorbable forms, and is made in the USA from U.S. and imported ingredients. Warnings state the product is contraindicated for anyone with a history of hypersensitivity to its ingredients, that pregnant or nursing women and women trying to conceive should not use it, and that there are no known adverse interactions or contraindications at publication date.

The main support for this product comes from Shoden ashwagandha extract at 120 milligrams, a full dose. In a trial of 60 stressed adults, 60 or 120 milligrams daily for 60 days raised testosterone in men by 22 and 33 percent, against 4 percent on placebo [1]. In 57 overweight men aged 40 to 70, 8 weeks of Shoden gave a 14.7 percent greater testosterone rise than placebo [2]. A third trial at 240 milligrams found a rise that was not clearly better than placebo [3]. Shilajit at 500 milligrams is also a full dose. In healthy men aged 45 to 55, purified Shilajit twice a day for 90 days raised total and free testosterone more than placebo [4]. A review judged it possibly effective for men with low testosterone later in life [5]. Zinc is at 15 milligrams, below the 50 milligrams that worked in one dialysis trial [6]. Most zinc trials found no hormone change [7][8]. Luteolin has only animal evidence for male hormones [9]. Its one human study did not measure hormones [10]. Animal and cell studies are never counted.

Across the stores, Thorne Advanced Testosterone Support capsules carry about 880 ratings, and the picture is mixed but leans positive. Many buyers report more energy and focus, while a smaller group notice nothing and say the price is too high. This summary covers the capsules only; reviews of other forms were left out. **What buyers say it did for them:** The most common report is more energy and focus, often with better workouts. Some feel it quickly, others only after weeks. One buyer wrote "Within 4 days... you really notice a difference." Another said "Feel way better than before, every man should try." A more measured reviewer saw "a subtle boost in energy and focus" within a couple of weeks and called it no "magic fix." One buyer on a Dutch-language store also reports better sleep, and another reports deeper sleep and a bigger appetite. One reviewer says a blood test before and after showed a benefit after 90 days. **What buyers complain about:** The main complaints are no noticeable effect and slow results. One reviewer says it "didn't increase energy levels or make any real difference." Another needed about a month to feel anything. A buyer on iHerb couldn't tell any difference after almost a full bottle. One three-star reviewer reported a drop in libido and apathy on days six and seven of a trial, suspected ashwagandha as the cause, and called it a dealbreaker. Another reviewer wished the milligram amounts were higher. One iHerb reviewer mentioned an aftertaste. **Taste, smell, pill size and form:** Reviewers describe the capsules as easy to take. One says they have "no unpleasant taste or smell," and another says "no bad taste." The single aftertaste complaint is the exception. No reviewer raises pill size as a problem, and one reports no side effects. **Value for money:** Opinions split. Critics say the price is high for the bottle size, and one hopes Thorne will offer "bigger packages with a better price." Another calls it "quite disappointing given the high price." Others are happy: one says it is a quality product at an affordable price, and another says the bottle size is enough. One enthusiastic buyer would "buy it again no matter the cost." **Who it seems to suit and who it did not:** It seems to suit people who want a gradual, supportive boost and trust Thorne's reputation for quality and clean ingredients. Reviewers also mention it works best alongside sleep, diet and training, and many are regular supplement users or trainers. It suited others less: buyers expecting fast or dramatic change, those who weigh price heavily, and the person who felt a libido drop. One Dutch reviewer takes two capsules in the morning on an empty stomach, because otherwise they sleep poorly. That differs from the page's suggested one capsule twice a day. Another cut from two capsules a day to one to manage hunger.

Biohacker Summary

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

Shilajit, the main ingredient, gets a split verdict from the panel: three of the seven who spoke about it recommend it, one uses it, two are neutral, and one stopped. Those who recommend it point to antioxidant benefits, help recovering from stress, and human data on testosterone and male fertility, with one citing 250 milligrams twice a day. The one who uses it adds a pinch to a favorite drink, while the neutral voices say the human trial evidence is thin, mostly animal studies, and that careful sourcing matters. One panelist tried about 20 kinds and felt nothing, so he stopped. Zinc is a smaller ingredient in this product, and the panel mostly recommends it, with doses of 15, 30, and 40 to 60 milligrams mentioned, and a few note it helps testosterone mainly when zinc is low.

Body systems: Endocrine system, Reproductive system

Combine with: For men using this product, it pairs well with vitamin D3 and K2 (vitamin D status correlates with testosterone), magnesium glycinate (supports sleep and testosterone-related recovery), boron, and ashwagandha (may lower cortisol and support testosterone). Omega-3 fatty acids and resistance training support overall hormonal and cardiovascular health. Zinc is already included, so pair it with copper if taking additional zinc long term. Women seeking hormone support should instead consider options such as vitex, magnesium, B6, omega-3s, or DIM with guidance from a clinician.

Possible side effects: The studies report that ashwagandha and luteolin were well tolerated. One reviewer reported lower libido and apathy, and another mentioned an aftertaste.
