Reseñas

Best supplier I've used so far 2026-09-22

Been through several vendors and Limitless Biotech is by far the best. Ordered Cagrilintide twice now. Both times shipping was fast (3-4 days). Product quality is consistently good. Their COA is from a third-party lab which is a big plus. Customer service actually picks up the phone. Prices are fair for the quality. Highly recommend.

Decent product but slow shipping 2026-09-19

Ordered Kisspeptin from Limitless Biotech. Product quality seems fine — it works. But shipping took 5 days which is longer than expected. Customer service took a couple days to respond to my inquiry. Pricing is average. Not bad but not great. Might try them again to see if shipping is faster next time.
