All Iron Shark Research peptides are guaranteed to be 99%+ pure. Each batch is independently tested by accredited U.S. laboratories using HPLC (High-Performance Liquid Chromatography) and Mass Spectrometry. A Certificate of Analysis (CoA) is provided with every order, detailing exact purity percentages, molecular weight confirmation, and amino acid sequence verification.

A Certificate of Analysis (CoA) is an official laboratory document that verifies the quality of your peptide. Key sections include purity (typically 99%+), identity confirmation via mass spectrometry, appearance matching the product description, and endotoxin levels (usually below 1 EU/mg). Each CoA is batch-specific and available on the corresponding product page.

Lyophilized (freeze-dried) peptides are highly stable. For short-term storage (under 3 months), they can be kept at room temperature in a cool, dark place. For long-term storage, refrigeration at 2–8°C or freezing at -20°C is recommended. Avoid repeated freeze-thaw cycles. When stored properly, lyophilized peptides can remain stable for 2+ years.

Lyophilized (freeze-dried) peptides are highly stable and can remain effective for 2+ years when stored properly at -20°C or 2–8°C. Always store them away from light and avoid repeated temperature fluctuations.

Orders are typically processed within 0–2 business days. After that, standard delivery takes about 3–5 business days. Every order comes with free shipping protection. Because the peptides are lyophilized, they remain stable at room temperature and do not require cold shipping. All packages are shipped in plain, discreet, unmarked packaging.

All Iron Shark Research peptides are intended strictly for research, laboratory, and educational use only. They are not approved for use in humans, animals, or for any medical or therapeutic purposes. By placing an order, you acknowledge that you are a qualified researcher and agree to use these products in compliance with all relevant laws and regulations.
