NuSci

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.

Ordered AOD-9604 from NuSci for lipolysis research. The COA they provided showed 96.8% purity, but when we ran our own HPLC analysis we got 93.2%. That's a bigger discrepancy than I'm comfortable with. I reached out to their support team with our test results and they were defensive rather than helpful. They eventually offered a partial refund but didn't acknowledge any quality control issue on their end. Shipping was fast at least. Not sure if I'll order from them again—there are too many reliable vendors out there to deal with inconsistent product quality.
