Shandong Shengyuan Peptide Technology sells to businesses rather than direct to researchers. It lists 14 products, including Tirzepatide, BPC-157, Semaglutide, Retatrutide, TB-500, and Semax, plus 5 other compounds. It also produces and labels to order, so stock sold under other brand names may come from here.
