We're seeing a lot of labs run GHK-Cu alongside NAD+ for mitochondrial repair studies — the works well in cellular energy models, but it's not for everyone; some find teh NAD+ degrades quickly if not stored at -20°C the moment it arrives.
Purity's typically 99% or higher, HPLC-verified on the COA, and endotoxin stays under 1EU/mg — most buyers just check those two numbers and move on, but that 24-month shelf life assumes you're keeping it dry with the desiccant in the sealed vial, no exceptions.
Bulk pricing kicks in around 50 grams or so, and we usually have stock on GHK-Cu, though NAD+ may need 2-3 weeks lead time if it's a large volume order — I'd say confirm before you quote your client, since custom synthesis isn't what we do here.
It dissolves in water, no issues there, but the molecular weight varies by peptide so don't assume same molar concentration across different batches — basically, weigh your doses fresh each time (check the COA for exact MW).
4.5 out of 5 buyers go with the 10mg vial format for research use, not sterile of course, and one thing they don't think to ask is we don't ship with dry ice unless you specifically request it for the NAD+ — someone melted theirs in transit last month, so pls plan for that.
We don't have a strict MOQ — you can order single vials for testing, but if you're planning bulk research, just let us know the quantities you need and we'll price it accordingly.
Standard lead time is 3-5 business days for processing, then shipping depends on your location. If you need it faster, we can expedite — just drop us a note at checkout.
Absolutely — each shipment includes a COA that shows the HPLC purity (≥99%), endotoxin level (<1EU/mg), and other QC results. Just request it with your order if it's not automatically included.
Store the lyophilized powder at -20°C in a dry environment. The desiccant helps, but once you open a vial, use it promptly to avoid moisture damage. Proper storage keeps it stable for up to 24 months.
We sell only to verified research institutions and labs — you'll need to confirm that the product is for in vitro or animal research, not human or veterinary use. Just make sure your account is set up for research purposes.
