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.

Excellent experience — fast shipping and COA included 2026-09-07

Ordered Growth hormone fragment from Limitless Biotech. Placed the order on Monday, received it by Thursday. Packaging was discreet and professional. COA was included and verified. Product quality is excellent — Growth hormone fragment worked as expected. Customer service responded to my questions within hours. Pricing is on the higher side but you get what you pay for. Will definitely order again.
