A single 10 mg research peptide vial generally sells for somewhere between $25 and $89 in 2026, and a 10-vial kit for between roughly $90 and $750 depending on the compound and the supplier. At Aegis Bio a Retatrutide 10 mg single vial is $25 and the 10 mg kit is $100. The spread is wide because vial price is a poor comparison: cost per milligram of peptide is the figure that compares cleanly.
Key facts
- Single 10 mg vials observed across vendors in September 2026 ranged from about $25 to $89.
- 10-vial kits ranged from about $90 to $750, depending on compound and strength.
- Price is driven by purity specification, certificate availability, domestic stock and vial count — not by the sequence alone.
- Aegis Bio shipping is $20 for carts of single vials and bacteriostatic water, $45 standard once a kit is included.
- WELCOME10 takes 10% off the items subtotal of a first order at checkout.
What drives the price of a research peptide?
Five things, in roughly descending order of how much they move the number.
- Milligrams, not vials. A 20 mg vial is not twice the price of a 10 mg vial, because a fixed share of the cost covers the vial, the fill and the handling rather than the material. Buying strength is usually better value than buying count.
- Purity specification. Pushing a synthesis from 95 to 99 percent costs purification passes and yield, and that shows up in the price.
- Documentation. A batch-specific certificate with a chromatogram is analytical work performed per lot. A generic specification sheet is not, and a catalog priced as though it were is comparing two different products.
- Domestic stock. Material already in the United States carries holding cost and ships in days. Material that is not carries a customs risk the buyer absorbs in time.
- Shipping, which is flat. A flat rate dominates a small order and disappears into a large one, so it belongs in the comparison rather than beside it.
Cost per milligram is the only clean comparison
Two listings for the same sequence at different strengths cannot be compared on sticker price at all. Divide the price by the total milligrams in the listing and the ordering frequently reverses. Then adjust for peptide content: a vial at 90 percent content delivers more peptide than one at 76 percent for the same label mass, and the sticker comparison points the wrong way. The arithmetic is worked through in single vials versus packs.

Prices are in USD and include the vial. Shipping is $20 for a cart of single vials and bacteriostatic water; any cart containing a kit ships $45 standard or $80 expedited, with single vials and bacteriostatic water riding along free; outside the United States it is a flat $80 on any cart. Live reductions are listed on the sale page.
Ipamorelin and CJC-1295
These two are priced against each other more often than anything else in the catalog, so the arithmetic is worth writing out. Ipamorelin 5 mg × 10 vials is $113, which is $11.30 a vial and $2.26 a milligram. CJC-1295 no DAC at the same strength is $145 ($14.50 a vial, $2.90 a milligram), and CJC-1295 with DAC is the dearer of the two forms at $221.
The co-lyophilised blend — CJC-1295 no DAC 5 mg with Ipamorelin 5 mg, 10 vials — is $168, against $145 plus $113 for the same material bought as two listings. The trade is that a blend is one cake in one vial, so the two components cannot be used at independent ratios.
For comparison, single 5 mg Ipamorelin vials are commonly listed at $30 to $60 by research vendors, and considerably higher through clinic channels. Specifications are on the Ipamorelin, CJC-1295 no DAC, CJC-1295 with DAC and blend pages.
Is a cheaper vendor actually cheaper?
Sometimes, and the way to find out has three steps. Convert both listings to cost per milligram. Adjust each by the stated peptide content, or treat a missing content figure as an unknown error of 10 to 25 percent. Then add shipping to both. A listing that survives all three is genuinely cheaper; most of the gap between the bottom and the middle of this market does not.
The cost that never appears on either listing is material you cannot use. A lot that arrives without documentation, or that behaves inconsistently between vials, costs a repeated experiment, which is almost always more than the saving that bought it.
Buying one vial first
A single vial answers the documentation question, the packaging question and the communication question for a fraction of a kit price. The cost-per-milligram premium on a single vial is the price of finding that out cheaply, and it is usually worth paying once. Single vials in this catalog include Retatrutide, Tirzepatide, BPC-157, GHK-Cu and MOTS-c.
