Hangzhou Youngpeptide Biotechnology HYB sells direct to researchers and at wholesale. The site says it has traded since 2020. It lists 145 products, including Sermorelin, Tirzepatide, Thymosin Alpha-1, Thymalin, Tesofensine, and Tesamorelin, plus 44 other compounds.

Worth knowing before you order: no card payments. Payment is limited to cryptocurrency (BTC). Neither route carries the chargeback protection a card payment gives you if an order never arrives or arrives wrong.
