How to Find the Right Research Compound
Use the filters to narrow the catalog by collection (Research Peptides, Peptide Blends, Metabolic, GLP-1 & Multi-Agonists or Bioregulators), set a maximum price or show in-stock products only. Every product page lists the available strengths, the per-capsule dose or spray concentration, storage conditions and the research areas the compound is studied in.
Research Peptide Formats Explained
Lyophilized (freeze-dried) vials are the most stable format for storage and let researchers prepare their own solutions. Capsules give a fixed amount per capsule for oral-format studies. Nasal sprays and serums arrive ready to use, with no reconstitution step.
Purity Testing and Certificates of Analysis
Peptide vials show the lot's purity by reverse-phase HPLC, with identity confirmed by mass spectrometry and endotoxin screening by an independent HPLC-MS laboratory. Published certificates of analysis are collected in our COA library and can be searched by product or lot number, and each product page shows whether the current lot's COA is available.
Fast US Shipping on Research Peptides
We ship to US addresses only, Monday through Thursday, with same-day dispatch on orders placed by 2 PM ET. Orders of $150 or more ship free within the US (free shipping does not apply to Alaska and Hawaii). Volume pricing is applied automatically in the cart: 8% off 3 or more of the same product and 12% off 5 or more, with different strengths counted together.
Larger and Recurring Orders
Labs that order the same compounds regularly save automatically through volume pricing, and our Wholesale page covers larger or recurring supply. If an order arrives with a wrong, damaged or missing item, contact us within 30 days of delivery for a free replacement or a full refund.
Why Researchers Choose Peplogy
We keep the catalog focused on compounds researchers actually study, list the research areas and lot documentation for each one, and answer questions through a US-based support team. Product pages, collection pages and the COA library are organized so you can compare strengths, formats and purity before you order.
For Research Use Only
Every Peplogy product is supplied strictly as a chemical reagent for laboratory investigation. Our products are not for human or veterinary use, and nothing on this site is medical advice.
Peer-reviewed studies on the research peptides in our catalog are indexed on PubMed, the research database of the US National Library of Medicine.
