Peptide Crafters

Peptide Crafters is a research peptide supplier operating as a certified purity reference standard provider, with approximately 92 active listings on Peptides.SO. The company's positioning as a supplier of reference standard-grade reagents reflects a more technically stringent quality tier than typical research vendor standards — reference standards are the benchmark materials used to calibrate analytical instruments and validate assay methods, representing the highest purity and characterization tier in compound classification.

The supplier's catalog compounds are supplied as lyophilized powders in acetate salt form, intended for non-clinical laboratory applications including chemical structure elucidation and in-vitro method development. The acetate salt form is the standard presentation for lyophilized peptides and ensures chemical stability during storage. The non-clinical laboratory and method development positioning reflects an end-use profile oriented toward analytical chemistry, method validation, and structural characterization research rather than biological assay applications alone.

The Peptide Crafters compound catalog covers the principal research peptide families. Growth hormone secretagogues include CJC-1295 (with and without DAC), Ipamorelin, GHRP-2, GHRP-6, and Hexarelin. Tissue repair research compounds include BPC-157 and TB-500 (Thymosin Beta-4). GLP-1 class metabolic research peptides include Semaglutide, Tirzepatide, Cagrilintide, and Retatrutide — reflecting coverage of newer-generation GLP-1 receptor agonist analogs studied in metabolic research. Melanocortin peptides (Melanotan-II, PT-141), longevity bioregulators (Epithalon, GHK-Cu, Thymosin Alpha-1), and cognitive research peptides (Selank, Semax) complete the catalog.

The reference standard positioning requires analytical verification commensurate with that tier — HPLC purity quantification, mass spectrometry identity confirmation, and in some cases NMR structural data — supporting researchers who need to document compound identity and purity for method development validation records.

Live per-mg pricing at Peptide Crafters (single-compound SKUs, affiliate URL confirmed against product name) places the catalog in the platform's mid-tier: CJC-1295 No-DAC from $30/mg, Semax and Selank both from $35/mg, Sermorelin from $35/mg, MOTS-c from $40/mg, Ipamorelin at $50/mg, TB-500 at $75/mg. One catalog distinction is the GHK-Cu format: Peptide Crafters stocks GHK-Cu in a large 8mL format (100mg total fill, $45/mg), which is atypically large for this compound on the platform and suited for researchers running extended skin extracellular matrix or wound-healing protocols.

All Peptide Crafters products are sold strictly for laboratory research, in-vitro method development, and non-clinical scientific investigation. They are not intended for human or veterinary use or consumption.
