High Purity Retatrutide Peptide | Excel Peptides for Research Use

Actually what makes this one stand out is the triple-action mechanism hitting GLP-1, GIP, and glucagon receptors all at once — most buyers go with the 15mg vial for longer studies. It's better than single-agonist peptides for broader metabolic research since you're not just targeting one pathway but three simultaneously. We usually have stock, but confirm lead time if you need more than 50 units or so.

The molecular weight sits at 3810.3 g/mol and it's a with HPLC purity north of 99%, so you get tight tolerance compared to less refined alternatives. Store it at -20°C long term or 2-8°C for short term, and it's soluble in sterile water or bacteriostatic water without much fuss.

5mg vials are fine for quick pilot work, but teh 10mg is pretty much the sweet spot for most labs we deal with. We've had researchers ask about the 30mg for long-running studies — not ideal if you're only doing a few assays since reconstituting that much at once can limit flexibility.

Every batch ships with COA, HPLC analysis, and mass spec data so you can verify what you're working with. What it does is give you confidence in numbers without having to run your own qualiy checks first. It's not suited for in vivo work in humans obviously, strictly research use only.

One detail that doesn't always come up in the spec sheet — the powder can pick up moisture if you're not careful during reconstitution, so work quickly and minimize open air exposure. The 30mg vial is noticeably larger in diameter than the 5mg, which catches some people off guard when planning storage.
