Frequently Asked Questions

No. Our products are research compounds supplied for laboratory research use only. They are not FDA-approved drugs, dietary supplements, or medical products, and no statements on this site have been evaluated by the FDA. They are not intended to diagnose, treat, cure, or prevent any condition.

Yes. A Certificate of Analysis ships with every order. Each COA documents HPLC purity testing and identity confirmation by mass spectrometry for the lot you receive, so your laboratory has documentation of what is in the vial before any research use.

Purity is verified by HPLC (high-performance liquid chromatography) analysis, with identity confirmed by mass spectrometry. Our peptides are supplied to a manufacturer specification of ≥98% HPLC purity, and the accompanying COA reflects the tested values for your specific lot.

Peptides are supplied as lyophilized (freeze-dried) powder in sealed glass vials, packed to limit light exposure and protect against transit damage. Orders ship discreetly with tracking. If a vial arrives compromised, contact support for a replacement.

Lyophilized means freeze-dried. The peptide is frozen and the water removed under vacuum, leaving a stable dry powder. In this form a peptide is far more stable for storage and shipping than it is in solution, which is why research peptides are supplied lyophilized and reconstituted only when needed.

Generally yes, when they are sold and labeled strictly for laboratory research use only and not for human consumption. These are not FDA-approved drugs. Laws vary by jurisdiction, and the buyer is responsible for compliance with all applicable federal, state, and local regulations. This is not legal advice.

"For research use only" means the material is intended for in-vitro and laboratory experimentation by qualified researchers. It is not for human or veterinary use, not a drug or supplement, and not to be administered to people or animals. Treat every product on this site under that restriction.

No. They are supplied exclusively for laboratory research use. They are not for human consumption, not for veterinary use, and not to be ingested, injected, or otherwise administered to any person or animal. Any use outside a research setting is outside the intended purpose of the product.

Per our Terms of Use, purchasers must be at least 18 years old and acquiring products for legitimate research purposes. By ordering you confirm you meet those conditions and that you will handle the material in accordance with applicable laws and good laboratory practice.

All sales are final — we do not accept returns or issue refunds. The one exception is items that arrive damaged in transit, which we replace. Full details are on our Shipping & Returns page.

Store lyophilized peptides at -20°C, protected from light. Once reconstituted, keep the solution refrigerated at 2–8°C and use it within roughly 28–30 days. Avoid repeated freeze-thaw cycles and prolonged light or heat exposure, all of which can degrade peptide integrity.

In short: add bacteriostatic water slowly down the inside wall of the vial, let the peptide dissolve without shaking, and swirl gently. The exact volume depends on your target concentration. Use our peptide reconstitution calculator and the step-by-step guide for the full method.

Bacteriostatic water is sterile water containing a small amount of benzyl alcohol that inhibits bacterial growth. Researchers use it as the diluent for lyophilized peptides because it lets a reconstituted solution be stored for longer without microbial contamination compared with plain sterile water.

A reconstituted peptide kept refrigerated at 2–8°C and protected from light is generally considered stable for about 28–30 days, though this varies by peptide. Stability drops with warm temperatures, light exposure, and freeze-thaw cycles, so prepare only what your work requires.

They differ in how many incretin receptors they engage. Semaglutide is a single (GLP-1) receptor agonist; Tirzepatide is a dual GIP/GLP-1 receptor agonist; Retatrutide is a triple GIP/GLP-1/glucagon receptor agonist. Each has been studied in preclinical and clinical research for metabolic and weight-related endpoints.

Both are studied in tissue-repair research but are distinct peptides. BPC-157 is a synthetic peptide derived from a gastric protein sequence; TB-500 is a synthetic fragment related to thymosin beta-4. Research suggests different proposed mechanisms, and some studies have examined them individually and in combination.

Orders ship from Las Vegas, NV, USA, typically within 24 hours, with tracking on every package. See the Shipping & Returns page for current carriers, timeframes, and details.

International availability depends on destination and applicable import rules, and our current shipping policy governs where and how orders are sent. Refer to the Shipping & Returns page for the latest, and note that buyers are responsible for compliance with their own country’s regulations.

Available payment options are shown at checkout. We are actively expanding the storefront — a full shopping cart and additional payment methods are being added — so the checkout page is the source of truth for what is currently accepted.
