Atlas Peptides is a research peptide company based in Nashville, Tennessee. We supply high-purity research peptides and blends for laboratory and scientific research. Every batch is third-party tested in the USA, and we publish the results so you can verify what is in the vial before you buy.

We are proudly based in Nashville, Tennessee, USA.

Our catalog includes BPC-157, TB-500, KPV, Semax, Selank, DSIP, CJC-1295 + Ipamorelin, MOTS-c, SS-31, AOD-9604, Tirzepatide, Retatrutide, PT-141, Thymosin Alpha-1, GHK-Cu, NAD+, Epithalon, Tesamorelin, FOXO4-DRI, and our KLOW blend. New compounds are added as the research develops.

Yes. Our best-known blend is KLOW, an 80 mg vial combining GHK-Cu (50 mg), BPC-157 (10 mg), TB-500 (10 mg), and KPV (10 mg). We also carry BPC-157 + TB-500. Blends are research formulations, not a single new molecule, and the evidence for each blend is the evidence for its individual components. No controlled trial has tested these combinations together.

Yes. Every batch is tested by an independent third-party laboratory in the USA. Quality you can verify is the whole point of the company.

A COA shows the batch number, the testing method (usually HPLC for purity and mass spectrometry for identity), and the measured purity for that specific batch. Match the batch number on the COA to the batch on your vial. If the numbers do not match, the COA is not for your vial. Everything we sell is tested at a lab here in Nashville.

It means the lab measured at least 99% of the sample as the stated peptide by the testing method used.

Keep lyophilized (powder) vials sealed, dry, and protected from light. For long-term storage, a freezer at -20°C is best and keeps them stable for years. A refrigerator at 2 to 8°C (36 to 46°F) is fine for vials you will use within the next year, and a cool, dark place at room temperature is fine for a few weeks. Let a frozen vial come to room temperature before you open it, so moisture does not condense into the powder.

Reconstituted material should be kept refrigerated at 2 to 8°C (36 to 46°F) and used within 28 days. Do not freeze reconstituted solutions: freezing damages peptides in solution.

No, we do not sell bacteriostatic water.

Peptides are short chains of amino acids, usually 2 to 50, linked together. They act as messengers in the body, telling cells what to do. Your body already makes thousands of them naturally.

Research peptides are peptides manufactured and sold for laboratory and scientific study. They are labeled research use only and are not intended for human or animal consumption.

Yes. Peptides sold for research purposes are legal to buy, own, and research in the US. Rules vary by country and by compound.

No. Our products are sold as research chemicals for laboratory research use only. They are not medicines, so prescriptions do not apply to them.
