Liberty Peptides

Liberty Peptides is an American research peptide supplier with over 68 active listings on Peptides.SO, operating in the domestic U.S. research compound market with a catalog that spans the principal peptide families studied in growth hormone biology, tissue repair, metabolic research, and longevity science. The company's brand positioning emphasizes domestic sourcing, transparent quality documentation, and accessible supply for independent researchers and research institutions alike.

The Liberty Peptides catalog covers the core research peptide compound families. The growth hormone secretagogue segment includes CJC-1295 (with and without DAC), Ipamorelin, GHRP-2, GHRP-6, Hexarelin, and Sermorelin — the standard GHRH/GHRP analogue stack studied in pituitary GH release, GH pulse pattern modulation, and IGF-1 axis signaling research. MK-677 (Ibutamoren) extends this coverage to oral GH secretagogue biology.

Tissue repair and regeneration peptide coverage includes BPC-157 and TB-500 in standard lyophilized vial formats and blended combination products. These compounds are among the most studied healing peptides in preclinical research, with literature covering tendon and ligament repair, gastrointestinal mucosal protection, cardiac healing, and systemic anti-inflammatory peptide effects. GLP-1 receptor agonist research compounds include Semaglutide and Tirzepatide, supporting metabolic research programs studying GLP-1 pharmacology, insulin secretion biology, and appetite regulation signaling.

Melanocortin peptide coverage at Liberty Peptides includes Melanotan-I, Melanotan-II, and PT-141 (Bremelanotide), covering the MC1R and MC4R receptor ligand space studied in pigmentation biology and central nervous system signaling. Longevity and bioregulator compound coverage includes Epithalon, Thymosin Alpha-1, and GHK-Cu, studied in telomere biology, immune modulation, and connective tissue research.

Ancillary supplies including bacteriostatic water and reconstitution equipment are available alongside the peptide catalog, supporting standard compound preparation per laboratory protocols. Multiple vial quantity options accommodate both single-experiment and extended research program supply needs.

Liberty Peptides' bioregulator line is uniformly priced at $2.75/mg across multiple 20mg vials (Cardiogen, Cartalax, Crystagen, Livagen), a flat per-mg rate across the bioregulator family. Standard GHRH/GHRP compounds price higher: CJC-1295 with DAC at $8.80/mg, CJC-1295 No DAC at $11.20/mg. GHK-Cu in capsule format (2mg × 60 capsules) reaches $35.00/mg, reflecting the expected capsule-format manufacturing premium over lyophilized-vial pricing. NMN supplement capsules (500mg × 60) work out to $0.10/mg, providing a materially cheaper per-milligram entry point for researchers who source supplement-category compounds alongside research peptides from a single vendor.

Third-party analytical testing (HPLC and mass spectrometry) provides purity verification with COA documentation per product. All Liberty Peptides products are sold exclusively for laboratory research and in-vitro scientific investigation. They are not approved for human consumption or veterinary use, and handling should conform to applicable institutional research protocols.
