01
Products
Peptides are short chains of amino acids — the building blocks of proteins — that function as biological messengers in the body. XtremePeptides carries a broad catalog including BPC-157, TB-500, Ipamorelin, CJC-1295, Semaglutide, Tirzepatide, Melanotan II, GHRP-2, GHRP-6, Hexarelin, Sermorelin, and many more. Visit our product page for the full current inventory.
All peptides are manufactured to research-grade purity (≥98%) and independently verified by third-party laboratories via HPLC and mass spectrometry. Certificates of Analysis (COAs) are available for every batch on the product pages.
We primarily stock lyophilized (freeze-dried) powder for maximum stability and shelf life. Select products may be available as pre-mixed solutions. Bacteriostatic water for reconstitution is also available in our accessories section.
COAs are linked on each product page under the "Lab Testing" tab. You can also request one by emailing support@xtremepeptides.com with your order number. All COAs include HPLC chromatograms, purity percentages, and molecular weight confirmation.

04
Storage & Handling
Lyophilized peptides should be stored at -20°C (freezer) for long-term stability — up to 24 months. For short-term use (up to 30 days), refrigeration at 2–8°C is acceptable. Keep away from light, moisture, and temperature fluctuations.
Use bacteriostatic water (BW) for multi-use reconstitution. Add BW slowly along the inside wall of the vial — do not inject directly onto the powder or shake vigorously. Gently swirl until dissolved. Reconstituted peptides should be stored at 2–8°C and used within 4 weeks.
It is not recommended — repeated freeze-thaw cycles degrade stability. If extended storage is needed, aliquot into single-use portions before freezing. Lyophilized powder can safely be returned to the freezer.
05
