Does the marketing hold up?

Category context: sexual-enhancement products carry documented FDA risk. This is category history, not proof about this product, but it changes how much unsupported claims deserve to be trusted.

What a serving costs$3.30per serving, at the checked price
Is it tested?Claimed — no lab or certificate found
Who’s behind it?USPTO lists 2 owner recordssame brand name, more than one registrant — we don’t choose between them
Is it the real thing?Barcode matches outside records
Trouble on record?No recalls found

“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

The checks, one by one

1 promise needs a closer look.

Partly confirmed1

“Ali, Fenugreek, Shilajit & Boron - Male Support - Libido, Energy & Muscle Growth Support -”

Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed.

Evidence →

Ingredient research can support context, but it is not a trial of this exact product.

Claimed without support found1

“to take full effect. If you do not see results in 90 days, contact us for a refund on your first”

We found no study of this product measuring the stated outcome over the stated timeframe.

?Couldn’t verify independently2

“Noticed increased strength with Mars Men. Made in USA Third Party Tested Non-GMO”

“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.

Evidence →
“strength with Mars Men. Made in USA Third Party Tested Non-GMO”

No named laboratory or lot-specific certificate was found for this exact product. A related brand page names no testing issuer and links no product-bound report; its UPC is not published. NSF, IFOS, USP, and Informed-Sport were not checked in this record. This is a public-evidence limit, not a finding that testing did not occur.

Evidence →

We looked and found no public proof. That does not count against the product.

Category context: sexual-enhancement products carry documented FDA risk

This is category history, not proof about this product, but it changes how much unsupported claims deserve to be trusted.

Evidence and sources

FDA's health-fraud program documents sexual-enhancement products as the most common supplement category found to contain undeclared prescription-drug ingredients. This is a category-level documented fact from FDA's public database — not a test result for this specific product. …

Public contextWho is behind it?

Registered owner records: Xufeng Liu · Mars Health, Inc.

The public ownership record is ambiguous. We show the exact candidates instead of choosing one by name similarity.

Evidence and sources

USPTO returned multiple live supplement-class records for the exact brand wordmark: Xufeng Liu, Mars Health, Inc.. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.

Checks outCan you trust the review pattern?

Reviews rose from 0 to 102 between April 28 and July 25, 2026 — no sudden jump.

A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.

Evidence and sources

Written reviews rose from 0 to 102 between April 28 and July 25, 2026. The largest rise inside any single 30-day window was about 74, so the count moved in steps rather than in one burst.
