Most orders ship within 1–2 business days. Standard delivery takes 3–5 business days depending on location. Expedited options available at checkout.

Store lyophilized vials at –20°C for long-term storage (months to years) or 2–8°C (refrigerator) for short-term storage up to several weeks. Protect from direct light, moisture, and excessive heat. Once reconstituted, peptides should be refrigerated and used within the recommended timeframe. Minimize freeze-thaw cycles by aliquoting reconstituted solutions.

All products are sold strictly for laboratory and scientific research purposes. They are not intended for human consumption, veterinary use, or any therapeutic application. By purchasing, you confirm that products will be used solely for lawful in vitro research and scientific investigation.

Kits are curated compound bundles organized by research category — Recovery, Neuro, Metabolic, and Elite series. Each kit contains two complementary compounds selected for related research pathways. Singles are individual vials that let you build a custom selection or restock specific compounds from any series.

We accept returns on unopened, undamaged products within 14 days of delivery. Contact us at hello@hotpeps.com with your order number to initiate a return. Opened or damaged products are not eligible for return.

All compounds in the Hot Peps catalog meet a minimum purity standard of ≥98%, with the majority tested at ≥99%. Purity is verified through reversed-phase high-performance liquid chromatography (RP-HPLC), and molecular identity is confirmed via mass spectrometry (MS). Third-party Certificates of Analysis (COA) are maintained for every production batch.

Hot Peps carries 9 precision research compounds across 4 series: Recovery Series (BPC-157, GHK-Cu), Neuro Series (Semax, Selank), Metabolic Series (Retatrutide, MOTS-C, KLOW), and Elite Series (PT-141, Melanotan II). All compounds are supplied as lyophilized powder in sealed, sterile vials.

Lyophilization (freeze-drying) is a preservation process that removes water from a peptide solution under reduced pressure. The resulting dry powder is more chemically stable than a peptide in solution, as the removal of water minimizes hydrolysis and other degradation reactions. Lyophilized peptides are reconstituted with an appropriate solvent before experimental use.

Yes. Email hello@hotpeps.com with the product name and lot number (found on your vial label) and we will provide the corresponding COA documentation. Each COA typically includes an HPLC chromatogram, mass spectrometry report, appearance description, lot number, and stated purity percentage.

Hot Peps organizes compounds into four series based on research focus: Recovery Series focuses on tissue and regeneration pathway research (BPC-157, GHK-Cu). Neuro Series focuses on cognitive and stress-response pathway research (Semax, Selank). Metabolic Series focuses on appetite and metabolic signaling research (Retatrutide, MOTS-C, KLOW). Elite Series focuses on specialty melanocortin pathway research (PT-141, Melanotan II).
