Both vials looked properly filled and the batch COA was in the box. Took six days to arrive, which is fine for domestic. ### ★★★☆☆ mixed *Jonathan T. — May 8, 2026* Tirzepatide order was solid, but my second order for NAD+ took over a week and support was slow to answer my email about it. Bit inconsistent. ### ★★★★☆ plain packaging but works *Mason Y. — Mar 30, 2026* Box was pretty basic and the labels are just printed stickers, but the BPC-157 itself was good and shipped within two days. Can not complain much. ### ★★☆☆☆ out of stock a lot *monica\_study — Feb 27, 2026* Half the things I wanted were sold out and the MK-677 I did order was backordered after I paid. They refunded fast at least but annoying. ### ★★★☆☆ Mixed experience with KPV and semaglutide order *Ethan Caldwell — Feb 9, 2026* Ordered both KPV and semaglutide for different projects. The semaglutide was good quality with a solid COA showing 98.1% purity. KPV was more questionable - reconstituted with some slight cloudiness that eventually settled but made me nervous about contamination. Customer service took 3 days to respond to my concerns which isn't great. Shipping was okay, about 5 days total. Prices are reasonable. The issue is quality control seems inconsistent between products. I'll probably use them again for semaglutide but might source KPV elsewhere. Not bad overall but not amazing either. ### ★★★★★ reordering *Justin O. — Feb 3, 2026* Quick domestic shipping, GHK-Cu was tested clean and reconstituted nicely. My go-to for now. ### ★★★☆☆ no ice pack *Anna F. — Jan 9, 2026* Semaglutide arrived but there was no cold pack in the box. It was cool outside so probably fine, still would have liked one for the price. ### ★★★★☆ COA on request *Adam N. — Dec 1, 2025* They do not post test results on the site but sent me the COA for my retatrutide batch within a day of asking. Decent purity numbers. ### ★★★★☆ Reliable BPC\-157 supplier *Sienna Park — Nov 5, 2025* Third order of BPC-157 from US Peptide Labs and they've delivered every time. Purity testing consistently shows 97-99% which is solid for the price point. Ships fast, arrives cold, vials are properly sealed. Customer portal makes reordering easy. My research group has had zero issues with their BPC batches. Price is fair compared to premium vendors. Would recommend for anyone doing injury recovery research protocols. ### ★★★☆☆ fine, nothing special *Brian W. — Nov 4, 2025* Average vendor honestly. Got my CJC-1295, it was fine, but prices are a little higher than a couple other domestic sources I use. ### ★★☆☆☆ underfilled vial *Alicia N. — Oct 11, 2025* My ipamorelin vial looked light compared to what I usually get. Emailed support and got a reply but it took four days. Not a great first impression. ### ★★★★☆ Great semaglutide source for metabolic research *Zoe Martinez — Oct 5, 2025* Been using US Peptide Labs for about 6 months now and they've become my go-to for semaglutide. The consistency batch to batch is what impresses me most - we've run mass spec on three different orders and the purity variance is less than 0.5% which is really tight. Their COAs are comprehensive with full amino acid sequencing data, not just basic HPLC. Shipping is fast, usually 3 days to the east coast. The lyophilization is done well so reconstitution is always smooth. Customer support is responsive via email, though they don't have live chat which would be nice. Pricing is mid-range but the quality justifies it. My only real complaint is their website search function is terrible - easier to just browse categories. Will definitely continue ordering from them for our obesity research protocols. ### ★★★★★ good experience *Brian Q. — Sep 23, 2025* Tirzepatide showed up well packed and the vials were filled to spec. Happy with my first order here. ### ★★★☆☆ shipping was slow *Donna U. — Sep 2, 2025* Product seems fine but it took nine days to arrive and I never got a tracking number until day six. Wish they communicated better. ### ★★★★☆ solid so far *andrew.q.training — Aug 14, 2025* Ordered BPC-157 and TB-500, both reconstituted clear with no floaties. COA was emailed when I asked. Will order again.
