Registered owner records: Muscle Feast, LLC · Sean Gillespie
The public ownership record is ambiguous. We show the exact candidates instead of choosing one by name similarity.
USPTO returned multiple live supplement-class records for the exact brand wordmark: Muscle Feast, LLC, Sean Gillespie. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.
Reviews rose from 21 to 43 between September 24, 2025 and August 11, 2026 — no sudden jump.
A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.

Written reviews rose from 21 to 43 between September 24, 2025 and August 11, 2026. The largest rise inside any single 30-day window was about 5, so the count moved in steps rather than in one burst.
No FDA recall matched this brand in the current search.
We have not found a public label filing for this exact product.
Barcode checksum is valid; no independent product record was found.
