Peptide Prices Today: Price per mg at Every Vendor We Review

What ten research compounds cost per milligram right now at the 13 vendors the Bureau has reviewed and can price, cheapest in-stock vial first, next to each vendor's Bureau score and what its certificates show. Prices are the product-page price before any code. A low price from a vendor with weak testing is not a bargain, which is why the score and the COA note sit beside every number.

This page replaces the Bureau's monthly Peptide Cost Per Milligram Index, whose September edition is kept at the bottom. The Bureau publishes it because sticker prices in this market are not comparable. A $60 vial of BPC-157 at one vendor holds 5 mg and at another 10 mg, a factor of two that no product page points out. Dividing by the milligrams removes that distortion. Nothing else does, which is why every table here carries a date.

How this table is built

A script reads each store's own product data (the WooCommerce Store API where the store runs on it, the product page data where it does not) and keeps only single-compound vials: no blends, sprays, tablets, capsules or boxes of ten. Price per mg is the listed price divided by the milligrams in the listing; for vendors that only sell packs, the smallest pack counts. Coded GLP listings are matched to a compound only where the Bureau's own review has already tied the code to it (Apollo, Amino Club); other vendors' coded listings are left out rather than guessed. Retatrutide and tirzepatide are investigational or prescription molecules; what is listed here are research-chemical vials, not pharmacy products, and the pharmacy price of tirzepatide is a different market (see retatrutide cost for the clinical side).

Scores come from the 2026 vendor scorecard. Links marked Check price earn the Bureau a commission at no cost to you; the order of every table is price per mg and nothing else.

Why per-milligram is the only honest comparison

The worked examples in this section and the next are from the September 2026 edition (5 September check); the live tables above carry today's numbers.

Thirteen different vial sizes appeared in the September edition: 2, 5, 7, 10, 15, 20, 30, 50, 60, 70, 75, 80 and 100 mg. Vendors choose them, and they choose different ones for the same compound. Three rows show what that does to a sticker comparison.

• BPC-157. Apollo at $59.99 and Pantheon at $60.00 look like the same price. Apollo's vial is 10 mg and Pantheon's is 5 mg, so they are $6.00/mg and $12.00/mg. Ascension's $49.00 for 10 mg, $4.90/mg, is both the lowest sticker and the lowest per-mg in that row, which is the exception rather than the rule.
• TB-500. Pantheon's $40.00 vial is the cheapest sticker in the row and, at 2 mg, the most expensive per milligram at $20.00/mg, more than three times Apollo's $6.00/mg for a 10 mg vial.
• Retatrutide. Ascension's R-10 at $99.00 is less than half Apollo's $210.99 sticker, yet Apollo's 30 mg vial works out cheaper per milligram, $7.03 against $9.90.

Blends need one more caution. A per-mg figure for GLOW or KLOW is dominated by the 50 mg of GHK-Cu in the vial, the cheapest component by far, so $1.79/mg for a 70 mg blend cannot be set against $6.00/mg for a 10 mg BPC-157 vial and called a bargain. Compare blends with blends. The GLOW stack guide sets out the component ratios.

Once the compound is chosen, the arithmetic moves from milligrams to doses. A 10 mg vial supports twice as many draws as a 5 mg vial at any given dose, and the peptide reconstitution calculator converts vial size, diluent volume and dose into units on a syringe and cost per draw. The Bureau's reconstitution guide covers the method.

What the price does not tell you

A per-mg figure is a unit price for a label claim. Four things sit outside it.

The certificate. All five vendors scored in September state batch testing on their own pages: Apollo shows a lab report image in each product gallery (a Janoshik report on the BPC-157 10 mg page); Pantheon publishes a COA per batch on its lab results page and links it from each product, naming Freedom Diagnostics, Chromate and Testides; Amino Club states an eight-assay panel per batch at an ISO 17025 laboratory, with the COA on the product page and in a library; Ascension shows batch-specific certificates from Kovera Labs and MZ Biolabs with view and download links; Limitless shows a COA with HPLC results on each product page and adds USP endotoxin and sterility testing on its premium tier. Those statements are the vendors' own. The peptide testing guide explains what a certificate can and cannot prove, and why a low per-mg figure with no lot-specific certificate is not a low price.

Fill. The denominator in every cell is the milligrams the label claims. Independent retest databases score vendors on fill as well as purity; Finnrick's pass standard, as recorded in the Bureau's Peptide Partners review, is purity of 99.5% or better and dose within 35% of label. A vial that is 20% under label is 25% more expensive per real milligram than the index shows. The Bureau has not weighed any vial and takes every label at face value.

Shipping. The thresholds differ and they matter most on a single vial. As stated by each vendor on the checked date: Apollo ships free over $200 and charges a flat $9.99 below it; Pantheon ships free over $200; Amino Club ships free over $100; Ascension charges a flat $15 domestic; Limitless charges $14 for FedEx 2-Day. For one vial of BPC-157 the delivered picture looks like this.

Two vials at Amino Club clear its threshold; two at Apollo or Pantheon do not. On a large order, shipping falls out of the comparison entirely and the per-mg figure is the whole story.

Movement. Sale prices change between checks. Ascension's listings in particular moved within the same week (next section), and Apollo's newsletter pop-up offers 10% off and free shipping to subscribers, which the index does not apply. The how to buy peptides guide covers the rest of the checklist.

How to quote these prices

Quote the per-mg figure rather than the sticker, include the date the price was read (shown at the top of this page), and link to the page so readers land on the current edition. For example: "BPC-157, $1.30/mg at Peptide Partners (80 mg, $104.00), Peptide Bureau price tracker, prices read 19 October 2026." Earlier editions stay on this page, so a quoted number stays verifiable.

For the number most readers actually want, cost per dose, use the peptide dosing calculator: enter the vial size and price from the table and a dose, and it returns doses per vial and cost per dose.

Does the index include coupon codes, sale prices or shipping?

It uses the price on the product page when the store is read, which includes a vendor's own running sale. It leaves out newsletter codes, partner codes, loyalty points, bulk tiers, crypto discounts and shipping. The codes the Bureau has verified are listed under the tables with the date they were checked; every other vendor discount is on the coupon codes page.

Is a lower price per milligram a sign of lower quality?

Price alone cannot tell you that in either direction. Whether a vial matches its label is a question for the certificate and for independent retesting, not for the price. The Bureau takes every label at face value here. Use the per-mg figure to rank vendors that already pass your documentation check, not to choose between a documented vial and an undocumented one.
