Tcore Biotech is a US-based vendor selling to both individual buyers and bulk customers, with a mid-sized catalogue. The site shows COAs from Vanguard Laboratories using HPLC, with reported purity averaging 99.8% — certificates cover just over half of its peptides. Pricing data is sparse (only a couple of offers are currently tracked), and community feedback is minimal: two customer-service mentions from a single source show mixed sentiment, not enough to draw a pattern.
