Thymosin Alpha-1 turns up at 31 of the suppliers we rate, 48 listings between them once you count every size. For the 10 mg vial most shops carry, expect to pay about $80; the lowest price we found was $35.50 at Trident Peptide UK, which scores 3.1 with our editors but shows no certificate on the product page. The 5 mg size runs about $55.40, $24.99 at the low end. That bottom price is well under half the typical figure, so read the certificate before you look at the cart total.

Prices are what the product page showed during our October 2026 check, before coupons and shipping. Pounds were converted to dollars at an approximate rate; the listed figure is shown beside it. The small per-milligram figure is for comparing odd sizes, not for shopping by. Every listing is sold for laboratory research use only. Spotted a change? Tell us.

Questions

Why does a 10 mg vial of Thymosin Alpha-1 cost $35.50 at one shop and far more at another?

Part of it is paperwork: a shop paying an outside laboratory for every lot has a cost the cheapest shop may not. Part of it is volume. And part of it is what each shop thinks you will pay. The typical price tells you what the market has settled on; the score tells you what, if anything, the extra money buys.

Is the cheapest Thymosin Alpha-1 listing safe to order?

We cannot tell you that from a price list, and neither can anyone else. What we can tell you is whether the shop lets you open a certificate before you pay, whether it has a public record worth worrying about, and how it scores against the field. 14 of the 48 listings here show a certificate right on the product page, which is the least you should ask for.

How current are these prices?

Each one was read from the supplier's own product page during our October 2026 check, before coupons and shipping. Shops move prices without telling anyone, so confirm in the cart.
