Simple Peptide

Simple Peptide is a U.S.-based research peptide supplier with one of the more format-diverse catalogs among domestic vendors, with over 118 active listings tracked on Peptides.SO. The company's product development philosophy emphasizes novel delivery systems alongside conventional vial formats, making it particularly relevant for researchers who prioritize administration method variety in their experimental designs.

A key differentiator in the Simple Peptide catalog is the Melts™ line — dissolvable oral strips for peptide delivery, a format uncommon among typical research peptide vendors. This proprietary format joins their standard oral peptides line (13 products), oral capsule offering (8 products), topical peptide range (11 products), and nasal spray formulations, giving researchers access to four distinct administration routes within a single vendor. The Simple Cosmetics line extends into skincare research compounds.

Compound coverage at Simple Peptide spans the full contemporary research peptide landscape. The GLP-1 and Amylin Research segment includes Semaglutide, Tirzepatide, and a dedicated GLP-2TZ Tirzepatide category (7 listings). Anti-aging peptides represent over 40 listings including GHK-Cu, Epithalon, and related longevity compounds. Immunomodulatory peptides number 17 catalog items. GH secretagogues cover Ipamorelin, CJC-1295, and related compounds. Additional segments include Exosomes (5 products), Glucagon Peptides, Melanocortin (Melanotan), Longevity compounds, Mitochondrial Health (5 products), Metabolic Health, and Aminos/LIPO/Coenzymes.

Lab Tested Products are grouped into a dedicated category (26 listings) for researchers who require documented quality assurance. The New Arrivals category with 34 products reflects an actively maintained catalog responding to emerging research interest areas. Bacteriostatic water and accessories complete the supply-chain utility.
