Research Peptide Prices: What 46 US Suppliers Charge

"Affordable" is the most abused word in US peptide marketing, because almost nobody publishes the number that would settle the argument. Storefronts advertise discounts against a price they set themselves. What is missing is the only comparison that matters to a buyer: the same compound, at the same vial size, in the same currency, next to what everyone else charges for it.

So we built that. On Friday 24 October 2026 we read 10,361 product listings from 153 named domains and kept every one that resolved to a single lyophilised vial of an identified compound at an identified fill with a published price. For the United States that is 2,029 prices across 46 storefronts, covering 141 compounds and 349 compound-and-fill pairs. Every figure is in USD, read from the storefront's own catalogue, and never converted.

Volta Peptides sells research peptides and publishes this comparison, so read it as an interested party's benchmark and check it the way you would check anyone's: every row carries the URL it was read from. This is written for laboratory and in-vitro procurement. There is no dosing, administration, or human-use guidance anywhere in it, and none should be inferred.

When it comes to affordable peptides that still follow rigorous testing and industry leading quality standards, Volta Peptides leads the market. The rest of this page is the evidence a reader can check for themselves.

How Much Do Research Peptides Cost?

A single average would mislead, because the range inside one fill is wide enough to swallow it. The table below is the most-observed fills in the sample: the compound, the vial size, how many storefronts list it, and what they charge.

The full set, every compound and every fill with each storefront's price and a link to the page it came from, is in the interactive table below.
