Good for: Men who want a clearly labelled, dose-disclosed T-support supplement and know it treats neither low T nor ED.

Skip it if: You have symptoms of low testosterone (get a blood test), prostate cancer, liver or thyroid disease, or take thyroid, diabetes, blood-pressure or sedative drugs (ashwagandha may interact).

Testosterone Support is made by Innerbody Labs, which Innerbody Research formed in 2024 as a division of the company that runs the Innerbody.com supplement reviews. That is a conflict of interest: Innerbody's own review of the product says it was "involved in its creation" and rates it the best value among T boosters. Read that review as the maker's own.

The label is the most honest in this comparison: 11 ingredients at disclosed doses, no proprietary blend, led by ashwagandha (600 mg), tongkat ali (400 mg), fenugreek, maca, zinc and vitamin D3. Some of these have small studies behind them, but we found no trial of the product itself. NIH says ashwagandha "might" raise testosterone, with rare reports of liver injury and possible effects on the thyroid, and a 2020 analysis of 50 T boosters found 90% claimed to raise testosterone while only 24.8% of those had data to back it. Our testosterone booster guide covers each ingredient.

A one-month bottle is $78 as a one-off order. Subscriptions are much cheaper but renew automatically at the then-current price, with a reminder email four days before each charge. The refund policy is fairer than most: 30 days from delivery, opened bottles accepted, you pay return shipping; international orders are final sale.

Verdict: the cleanest deal here, for a product that can at best nudge testosterone in men who are already normal. If you are tired, low on libido or struggling with erections, get your testosterone measured by a doctor; real low T and ED have real treatments (see ED treatments that work).

The facts

Cost
On the product page (Nov 10, 2026): $78 for one month, $234 for three, $468 for six as one-time orders. Subscriptions are discounted (a Black Friday offer of up to 55% off the first subscription order was running) and renew automatically at the then-current price until cancelled, with a reminder email 4 days before each charge.[1][2]
What it claims
Sold to support testosterone, energy and libido with 11 ingredients at disclosed doses and "no proprietary blends", led by ashwagandha (KSM-66, 600 mg), tongkat ali (400 mg), fenugreek, maca, zinc (25 mg) and vitamin D3. It says the product is third-party tested.[1]
Evidence
We found no trial of the finished product. NIH's Office of Dietary Supplements says ashwagandha "might" raise testosterone and notes rare liver-injury reports, and a 2020 analysis of 50 "T booster" supplements found 90% claimed to raise testosterone but only 24.8% of those had supporting data. Innerbody Research, which makes it, also runs the review site that rates it the best-value T booster, so read that review as the maker's own.[3][4][5][6]
Billing & refunds
30 days from delivery to start a return, and opened or used bottles are accepted; you pay return shipping. International orders are final sale. Cancelling a subscription mid-term does not refund orders already charged or shipped.[7][2]
FDA & FTC actions
We found no FDA warning letter, hidden-drug notice, recall or FTC action naming Innerbody Labs, a brand launched in 2024. That is not proof of safety: FDA does not approve supplements before they are sold.[8]
