How Much Do Peptides Cost? 2026 Research Peptide Price Guide

Research peptides cost roughly $50 to $360 per vial at Clean Peptide, depending on the compound and the vial size. On 25 October 2026, list prices ran from $48 for a 50 mg GHK-Cu vial to $360 for a 50 mg SS-31 vial, and most 10 mg vials listed between about $53 and $108. Per milligram, that is from under $1 for GHK-Cu to more than $20 for thymosin alpha-1. The tables below show today’s prices, read live from the store.

This guide covers research-grade reference materials sold for laboratory use. It does not cover prescription peptide medicines or clinic programmes, which are priced, regulated and supplied in a completely different way.

Price per milligram is the number to compare

A vial price on its own says little, because vials hold different amounts. Dividing the price by the milligrams in the vial gives a figure that can be compared across sizes and suppliers. In our catalogue, larger vials of the same peptide cost less per milligram. On 25 October 2026, list prices per milligram were:

Peptide	Smaller vial	Larger vial
BPC-157	10 mg: $6.44 per mg	20 mg: $5.27 per mg
GLP-3 Reta (retatrutide)	10 mg: $9.76 per mg	20 mg: $7.35 per mg
SS-31	10 mg: $9.25 per mg	50 mg: $7.20 per mg
GHK-Cu	50 mg: $0.96 per mg	100 mg: $0.72 per mg

What a price does and does not tell you

Two vials at the same price are only comparable if they are the same material with the same evidence behind them. Before comparing prices between suppliers, check:

• The same compound and form. A blend is not a single peptide, a spray solution is not a lyophilised vial, and different salt forms weigh differently.
• Measured content, not just the label. A certificate that reports net peptide content shows how much peptide the lot actually contains, which can differ from the labelled milligrams.
• What the certificate covers. A full panel (identity, purity, content, endotoxin, sterility, heavy metals) is more work than a purity-only report. Each of our product pages says which tests its certificate includes.
• The lot. The certificate should be for the lot that ships, with the same lot number as the vial.
• Delivery. Shipping cost and speed change the real total. Our terms are on the shipping page.

A low price is not proof of poor quality, and a high price is not proof of good quality. The documentation is what tells them apart. See where to buy research peptides: 10 checks and peptide testing.

Why research peptides are not priced like medicines

Approved peptide medicines, such as insulin or the GLP-1 receptor agonists, are manufactured and sold under a drug approval and dispensed on prescription, and their prices reflect that system. Research peptides are laboratory reference materials: they are not approved for human use, carry no dosing information, and are sold only for in-vitro research. Comparing the two on price is comparing different products.
