A nine-amino-acid peptide first isolated from rabbit brain. Research listings are usually 5 mg vials.
DSIP turns up at 35 of the suppliers we rate, 62 listings between them once you count every size. For the 5 mg vial most shops carry, expect to pay about $40.75; the lowest price we found was $14.99 at Eternal Peptides, which scores 2.5 with our editors but shows no certificate on the product page. That bottom price is well under half the typical figure, so read the certificate before you look at the cart total.
18 of 62 show a certificate on the page (29%). Pricing is 10% of the score; how we score.

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.
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.
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. 18 of the 62 listings here show a certificate right on the product page, which is the least you should ask for.
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. Prices listed in pounds were converted to dollars at an approximate rate. The whole table is yours to download at /data/prices.csv.
