You're looking at a range of peptides that basically covers GHK-Cu, MT2, Retatrutide, Semax, DSIP, and Epitalon, all lyophilized powder with ≥99% purity verified by HPLC and MS—not a batch slips without both. CAS for GHK-Cu is 49557-75-7 if that matters for your paperwork, but the others have their own identifiers.
We keep them at -20°C in dry storage, and if you're ordering in warmer months, we'll use tempearture-controlled packaing (usually 2-4 weeks lead time on those shipments). Most buyers go with the 10mg vial for initial work, but our company offer 2mg, 5mg, 15mg, 20mg, and 30mg depending on yield you're after.
The molecular weight varies by compound so don't expect a single number across all—it's specific to each peptide, and we include that on the COA. Not everything here dissolves identically either, though they're all water soluble; Retatrutide can be a bit slower to go into solution than GHK-Cu, so plan for gentle agitation.
These aren't for cell work with impure batches you'd get from some suppliers—this is synthetic production, not extraction, so what you get is tighter tolerance than reagent grade from a catalog. 2 years shelf life if you keep it dry and frozen, but we've seen vials lose potency faster if opened and resealed repeatedly.
A detail you wouldn't think to ask: teh vials are sterile but we don't guarantee sterility after opening—so don't assume it stays clean for multiple uses. Anyway, MOQ is literally a single vial, so you can test one compound without committing to bulk.
For researchers working on or mechanism studies, our company have stock typically on GHK-Cu and MT2; DSIP and Epitalon run shorter supply and may need a confirm on lead time before ordering.
It means you're getting less than 1% impurities, so your dosage and outcomes won't be skewed by contaminants. We run HPLC and MS analysis on every batch to back that up.
Our MOQ is one vial, so you can grab a single 2mg or 30mg vial to test the waters. No need to stock up on bulk you don't need yet.
If you keep it at -20°C in a dry spot, it'll hold for 24 months from the date we ship. Just don't let it thaw and refreeze repeatedly.
We'll send you the HPLC and MS analysis reports for your batch—so you can see the purity and identity yourself. No secrets here.
We stick to the 2mg, 5mg, 10mg, 15mg, 20mg, and 30mg sizes listed. If you need something outside that range, just reach out—we can sometimes adjust for larger research orders.
