Wholesale pricing
Thymosin Alpha-1 wholesale prices
$1.18/mg at Sema Peptides, the lowest of 20 suppliers we track. The dearest is $28.90/mg — 24× the price for the same milligram. Last checked September 18, 2026.
Bulk suppliers quote per-gram and sell by enquiry, so their cost per mg is far below retail and is not a price you can check out at. Use these for sourcing, not for comparing consumer prices.
