NuSci

Pricing is fair and shipping is fast. Free shipping kicked in over $200 which was nice. Vials all sealed correctly.

Semaglutide order arrived well packed with an ice pack still cold. Knocked a star because the COA doesn't name the lab that did the testing, but otherwise solid.

Few orders in now, PT-141 and BPC-157. Always packed neat and labeled properly. COAs are posted but I wish they listed the testing lab.

Cheaper than a couple other sources I checked for retatrutide. Checkout was simple and it shipped quick.

Bought GHK-Cu and Epithalon. Both came packed well and labeled clearly. Email reply took about a day which is fine.

MK-677 and GHK-Cu arrived in a few days, well packed. Pricing is reasonable and the site is easy to use.

NuSci has been my go-to for Semaglutide over the past 8 months. We're conducting appetite regulation studies and need consistent product quality batch to batch. So far they've delivered—every shipment tests around 97-98% purity. COAs are thorough and from a reputable testing lab. Shipping averages about 4 days to the west coast. Their prices are middle of the road, not the cheapest but not gouging either. Customer service is hit or miss—sometimes they respond same day, other times it takes 48 hours. Overall a solid vendor that I'd recommend for routine research needs.

Solid vendor overall, fast shipping and clean vials. Only gripe is ipamorelin has been out of stock the last couple times I checked.

Tirzepatide and BPC-157 order, both shipped quick and arrived sealed. Prices are competitive. COA was posted online.
