Got my order from MedFit Peptides last week and ran the COAs against an outside lab. Purity matched within tolerance, packaging was discreet, and shipping was 3 days to the east coast. Honestly the smoothest reorder I've had in months.
I used to rotate through 4-5 suppliers depending on what I needed for research. After two clean orders from MedFit Peptides I just consolidated. Catalog covers what I need, prices are reasonable, and support actually answered an email in under 24h.
Third lot in a row from MedFit Peptides hit the same purity numbers on my end. No clumping, clean dissolution, and the rubber stoppers actually hold up. Not paid, not sponsored — just nice to find a vendor that doesn't make me cross my fingers.
One vial was short on my last order. Sent a photo, they replaced it next business day and threw in a freebie. Small thing but it's why I keep going back instead of gambling on the cheaper sites.
