Peptides Source

Peptides Source is a research peptide vendor with a catalog of over 137 active listings on Peptides.SO, positioning itself as a precision-quality supplier to the scientific research community with an emphasis on sourcing rigor, analytical verification, and supply consistency. The company's catalog covers the principal research peptide compound classes with a product range designed to serve both institutional research applications and independent laboratory investigators.

The compound coverage at Peptides Source spans the main research peptide segments. Growth hormone secretagogue coverage includes CJC-1295 (with and without DAC), Ipamorelin, GHRP-2, GHRP-6, Hexarelin, and Sermorelin — the standard GHRH/GHRP stack components studied in GH secretion, IGF-1 modulation, and pituitary signaling research. Tissue repair and regeneration peptides include BPC-157 in multiple formulations and TB-500 (Thymosin Beta-4), both extensively studied in wound healing, musculoskeletal repair, and inflammation research contexts.

GLP-1 class metabolic research compounds include Semaglutide and Tirzepatide, reflecting the catalog's update to include the newer generation of GLP-1 receptor agonists studied in metabolic and metabolic-related disease research. Melanocortin research peptides (Melanotan-II, PT-141) and longevity/bioregulator compounds (Epithalon, Thymosin Alpha-1, GHK-Cu) complete the core range. IGF-1 variants (LR3, DES) and fragment peptides serve researchers working in anabolic signaling and tissue growth research contexts.

Quality control at Peptides Source follows the research vendor standard of independent third-party HPLC and mass spectrometry testing, with COA documentation provided for catalog products. Purity targets are 99%+ analytical grade across the catalog. Rigorous quality control measures are applied throughout the sourcing and testing process to ensure compound efficacy and identity consistency across batches.

Verified single-SKU pricing on Peptides.SO: MOTS-C ranges from $4.75/mg at the 40mg size ($190) down to $6/mg at the 10mg size ($60), a meaningful bulk discount for researchers who don't need frequent reorders. Selank shows a notable same-size price spread across two separate 5mg listings ($30 vs. $50, i.e. $6/mg vs. $10/mg) — worth flagging for researchers comparison-shopping within Peptides Source's own catalog before assuming a single price point. Sermorelin runs $65 for 10mg (~$6.50/mg), and Tesamorelin sold standalone (not blended with Ipamorelin) is $180 for 20mg (~$9/mg). BPC-157 with arginine — a modified formulation rather than plain BPC-157 — is $50 for 5mg (~$10/mg).

Shipping is available domestically within the United States. All Peptides Source products are sold exclusively for laboratory research and in-vitro scientific investigation. They are not intended for human consumption, veterinary use, or clinical application, and handling should conform to applicable institutional research protocols.
