What does a research peptide actually cost in the U.S. right now? We checked the listed prices at 10 U.S. research peptide vendors with public online stores, covering 212 product listings, and compared the same vial size for 17 commonly listed compounds. This is the October 2026 edition. We update the numbers each month on this page.
All compounds discussed are sold for laboratory research use only. This report covers listed prices and is not guidance for human or veterinary use.
Key findings
- The same vial can cost three times as much from one vendor as another. A 10 mg vial of BPC-157 ranged from $29.32 to $88.00, with a median of $51.50.
- The widest price gaps were MT-2 (3.1x), BPC-157 (3.0x) and MOTS-c (2.9x), measured from the lowest to the highest listed price for the same size.
- On average, the most expensive vendor charged 2.4x the cheapest for an identical vial size across all 17 compounds.
- Price alone tells you nothing about what is in the vial. None of these numbers show purity, identity or fill amount. Only a batch-specific Certificate of Analysis does.

October 2026 price table
Listed (non-sale) prices for a single vial of the most common size, in U.S. dollars. “Median per mg” divides the median vial price by the vial size.
| Compound | Vial size | Vendors | Lowest | Median | Highest | Median per mg |
|---|---|---|---|---|---|---|
| BPC-157 | 10 mg | 9 | $29.32 | $51.50 | $88.00 | $5.15 |
| TB-500 | 10 mg | 8 | $46.99 | $62.49 | $89.00 | $6.25 |
| GHK-Cu | 50 mg | 6 | $29.99 | $35.40 | $68.00 | $0.71 |
| Ipamorelin | 10 mg | 7 | $37.95 | $57.20 | $95.00 | $5.72 |
| CJC-1295 (no DAC) | 10 mg | 6 | $44.95 | $86.50 | $95.00 | $8.65 |
| Sermorelin | 5 mg | 6 | $39.99 | $47.00 | $59.99 | $9.40 |
| Tesamorelin | 10 mg | 8 | $55.99 | $79.28 | $138.00 | $7.93 |
| MOTS-c | 10 mg | 8 | $29.95 | $52.00 | $88.00 | $5.20 |
| Semax | 10 mg | 6 | $32.95 | $47.49 | $79.00 | $4.75 |
| Selank | 10 mg | 8 | $31.29 | $47.49 | $85.00 | $4.75 |
| Epithalon | 10 mg | 5 | $26.95 | $39.99 | $48.00 | $4.00 |
| PT-141 | 10 mg | 8 | $32.99 | $44.99 | $85.00 | $4.50 |
| MT-2 | 10 mg | 9 | $27.95 | $44.99 | $88.00 | $4.50 |
| KPV | 10 mg | 10 | $30.65 | $49.50 | $88.00 | $4.95 |
| NAD+ | 500 mg | 7 | $39.99 | $59.99 | $98.00 | $0.12 |
| GLP-3 RT | 10 mg | 4 | $41.99 | $87.49 | $108.00 | $8.75 |
| GLP-2 TZ | 30 mg | 4 | $99.99 | $129.99 | $188.00 | $4.33 |
GLP-3 RT and GLP-2 TZ are the code names we use for these two compounds. Fewer vendors in our sample listed them at the reference size, so treat those two rows as a smaller sample.
Why prices vary so much
Several things drive the gap between the cheapest and most expensive listings:
- Batch size and sourcing. Vendors that buy large lots from wholesalers can price lower than those who order small, dedicated batches.
- Testing. Independent third-party testing runs hundreds of dollars per batch. Some vendors test every batch, some test occasionally and some rely on the manufacturer’s paperwork.
- Where it is made and shipped from. Domestic production, cold storage and fast U.S. shipping all add cost.
- Fill accuracy. A vial labeled 10 mg is only worth its price if it contains 10 mg. A low price per labeled milligram can hide a low actual fill.
How to compare vendors beyond price
Before price, check that a vendor can show what is actually in the vial:
- A Certificate of Analysis for the batch you receive, not a generic or years-old report.
- Both purity and identity. HPLC shows purity. Mass spectrometry confirms the compound is what the label says.
- A way to verify the report with the lab that issued it, so you are not relying on a PDF the vendor could edit.
- A match between the COA and your vial: same compound, same strength and same batch number.
Our guide How to Read a Peptide COA walks through each section of a report and the red flags of a forged or reused one.

Methodology
- When: prices collected October 17, 2026.
- Who: 10 U.S. research peptide vendors that publish prices in a public online store. Vendors are not named, and Rogue Compounds’ own prices are not included.
- What: the regular listed price of a single lyophilized vial. Sale prices, discount codes, bulk pricing, bundles, blends, capsules, sprays and shipping are excluded.
- Matching sizes: each compound is compared at one reference size. Listings within 10% of that size count (for example, 9.5 mg counts toward 10 mg). If a vendor listed the same size twice, the lower price is used.
- Minimum sample: a compound appears only if at least 4 vendors listed it at the reference size.
- Limits: listed prices change often and this is a sample, not every vendor in the market. Prices say nothing about quality or testing.

Frequently asked questions
How much does BPC-157 cost in the U.S.?
In October 2026, a 10 mg research vial of BPC-157 had a median listed price of $51.50 across 9 U.S. vendors, ranging from $29.32 to $88.00.
Is a cheaper research peptide worse?
Not necessarily, but price can’t tell you. The only way to know what is in a vial is a batch-specific Certificate of Analysis showing purity (HPLC) and identity (mass spectrometry), ideally verifiable with the testing lab.
How often is this report updated?
Monthly. Each edition replaces the table on this page, and the date at the top shows when the prices were collected.
Are these products for human use?
No. Research peptides are sold for laboratory research use only. They are not for human or veterinary use, and nothing in this report is medical advice.
