Frequently Asked Questions

All Carbon Biosupply products are intended strictly for in-vitro laboratory research and are not for human or animal consumption. Research is to be performed only by qualified professionals in accordance with applicable laws and regulations.

Every lot we release is verified by a third-party ISO 17025-accredited laboratory. Tests include HPLC, LC-MS, and appearance evaluation. A Certificate of Analysis (COA) is available for each lot in our COA Library, indexed by lot number and release date.

Lyophilized peptides may appear as a compacted disc, loose cake, or fine powder. These variations are normal and do not affect purity or potency provided seal, color, and lot number check out.

Peptides ship lyophilized. Reconstitute with bacteriostatic or sterile water per your protocol. Target concentration and diluent volume are documented on the COA for each lot.

Store lyophilized material at -20°C (long term) or 2–8°C (short term, <30 days). Once reconstituted, store at 2–8°C and use within 28 days. Protect from light and humidity.

Small amounts of precipitation or flaking in reconstituted solution can result from pH drift or temperature shock. Gently warm to room temperature and swirl; do not shake. Contact support if the issue persists.
