Starts at about 4.1kDa molecular weight and comes as a — we see it used for neuroprotection and cognitive enhancement work mostly, but some labs are looking at the metabolic angle too. Purity's over 99% by HPLC, and it's the acetate form which handles better in solution than the straight peptide.
It basically dissolves in water at 5mg/ml, which is pretty convenient for dosing in most protocols. But you don't want to leave it out — store at -20°C, protect form light, and we usually have stock but confirm lead time on larger orders (20 days or so).

Most buyers go with 10mg vials for their initial study runs, though we can pack it however you need. One thing we found: it's not ideal for anything involving long-term room temperture storage, teh stability just isn't there outside of freeze conditions.
The transport includes a safety package with ice packs, so it arrives cold — we've had people assume it ships ambient, which it doesn't. We'll send COA with each batch, HPLC and mass spec verification included.
Anyway, MOQ is typically 1 gram or 100 vials, whichever works for your scale. Give or take on exact shipping costs depending on your region.
Our MOQ for Retatrutide is typically 1 gram, but we can discuss smaller trial amounts for first-time buyers. Let us know your requirement.
We usually ship within 3-5 business days after order confirmation. For bulk orders, it may take 7-10 days depending on quantity.
Yes, we include a COA with every batch, confirming the ≥99% purity by HPLC and other specs. Just request it when ordering.
Keep it at -20°C, protected from light, in the original safety packaging. Once reconstituted, use immediately or store briefly at 2-8°C.
We can customize packaging and labels for research institutions, but MOQ may apply. Just tell us your specs and we'll work it out.
