Guru Peptides

Guru Peptides is a U.S.-based research compound supplier with approximately 64 active products tracked on Peptides.SO, operating with a multi-category catalog that spans research peptides, SARMs, research chemicals, and laboratory bulk supply. The company's catalog structure reflects positioning as a full-spectrum research compound source for investigators who need access to multiple compound classes from a single vendor.

The Peptides category forms the core of the Guru Peptides offering with 32 listings covering the principal research peptide classes: GH secretagogues (Ipamorelin, CJC-1295), tissue repair peptides (BPC-157, TB-500), GLP-1 metabolic compounds (Semaglutide, Tirzepatide), melanocortin peptides (PT-141), and longevity compounds (Epithalon, GHK-Cu). The SARMs category (13 listings) covers selective androgen receptor modulators including RAD-140, LGD-4033, Ostarine (MK-2866), Cardarine (GW-501516), and related compounds studied in muscle biology and metabolic research. Research Chemicals (21 listings) extend into ancillary compounds used alongside primary peptide research. Catalog Chemicals add a further 21 listings for investigators sourcing research reagents. The Bulk Chemicals category (3 listings) serves researchers requiring higher-volume procurement.

A notable commercial feature is the Buy One Get One section (33 listings), representing active promotional pricing on a substantial portion of the catalog — a relevant consideration for researchers managing tight procurement budgets or stocking multiple compounds simultaneously. Lab Equipment (2 listings) provides basic procurement utility for common laboratory supplies.

Quality at Guru Peptides follows the third-party verification model standard in the domestic research supplier market, with HPLC purity and mass spectrometry identity confirmation for catalog product characterization. COA documentation is available and researchers should verify batch-specific data before use in experimental protocols.

Guru Peptides operates at the value end of the market across both lyophilized peptides and liquid research compounds. Lyophilized peptides: GHRP-6 5mg at $4.40/mg, CJC-1295 no DAC 5mg at $5.20/mg, CJC-1295 DAC 5mg at $6.60/mg, PT-141 10mg at $3.20/mg, Melanotan I 10mg at $3.20/mg, Epithalon 10mg at $3.30/mg, Fragment 176-191 5mg at $5.00/mg, TB-500 5mg at $7.00/mg, and SNAP-8 10mg at $2.30/mg. Liquid research compounds (SARMs, ancillaries) in 30mL vials: Clomiphene $0.56/mg, Letrozole $1.00/mg, GW-501516 $2.90/mg, and Anastrozole $29.99/mg (1mg/mL low-concentration format). Nasal spray formats (GHRP-2 nasal) are priced at approximately $2.00/mg. Most lyophilized peptides land between $3–$7/mg, making this supplier notably more affordable than mid-market peers.

All Guru Peptides products are sold exclusively for laboratory research, in-vitro investigation, and chemical research applications. None are approved for human consumption, clinical trials, or veterinary use.
