The same two vials, shipping and reviews, checked on each store's own site.
We compared eight US research peptide stores, Prism Labs included, on what you can check yourself: the list price of the same two vials, the free-shipping threshold, same-day shipping cutoffs and Trustpilot reviews. On November 4, 2026, Pure Health Peptides had the lowest prices on both vials, PS Peptides shipped every order free, and Prism Labs had the lowest free-shipping threshold among stores that charge for shipping. We publish this page, so each store's figures link to its own site.

Prices are for one vial of BPC-157 10 mg and one of GHK-Cu 50 mg, before any discount code. Prism Labs is listed first because we publish this page; the others follow by the 10 mg price, lowest first.

02
How we compared the stores
Every figure came from the store's own website or its Trustpilot page:
- Price: the single-vial list price of BPC-157 10 mg and GHK-Cu 50 mg, two compounds every store here sells. A sale price shown on the product page counts; codes and multi-vial discounts do not.
- Shipping: the order size that ships free, and the same-day cutoff as each store states it. A store that names no cutoff has none listed.
- Reviews: the Trustpilot score and review count. Some stores show no rating there.
- Date: read on November 4, 2026. Prices and promotions change often, so check before you order.
03
What the price does not tell you
A label is a claim. In a 2024 study, researchers test-bought a prescription peptide from unlicensed online sellers and found vials far below their labeled purity. A low price only helps if the store can show what is in the vial.
Before you order from any store, match the lot number on the vial to a published report, and check the report shows identity, purity and content. The full checklist: how to vet a research supplier. How to read the report itself: how to read a peptide COA.
04
What “research use only” means here
Stores like these sell peptides labeled for research use only, meaning laboratory research, not use in people. FDA has written guidance on products labeled that way. Background: what are research peptides.
05
Where Prism Labs fits
Prism Labs prices on this page are live from our catalog. Orders placed before 4:30 PM Central ship the same day, seven days a week, and standard shipping is free over $125. Each lot's lab report is on its product page and on the Quality & Testing page. Browse the catalog.

Questions, answered
What is the best peptide company?
There is no single best store for everyone. Compare the same vial's price, whether each lot's report matches the vial you receive, shipping speed and reviews. The table on this page does that for eight US stores.
Which peptide company is the cheapest?
On November 4, 2026, Pure Health Peptides had the lowest list prices on both vials we checked: $40 for BPC-157 10 mg and $29 for GHK-Cu 50 mg. Shipping and promotions change the final price, so compare totals at checkout.
Which peptide stores ship the same day?
Most stores here state a same-day cutoff, from 11 AM Pacific to 4:30 PM Central. Prism Labs ships the same day seven days a week for orders before 4:30 PM Central.
How do I know a peptide company is legit?
Match the lot number on your vial to a published report that shows identity, purity and content, and check for clear research-use labeling and a way to reach a person.
Are these peptides for human use?
No. Prism Labs sells its peptides for laboratory research use only.
