High Purity 99.9% Weight Loss Peptide GHK-Cu Mazdutide Glutathione MOTS-C Retatrutide for Research

Let’s be upfront—these are research-grade peptides, not for human use, so don’t expect clinical approvals, but for metabolic studies and weight management research, purity hits ≥99.9% with endotoxin levels under 0.1 EU/mg, which is better than reagent grade for this kind of work.

We’ve got pricing tiers that make sense: sample sizes at 5mg or 10mg for around $50-$80, mid-range 15mg to 20mg vials at roughly $120-$180, and bulk 30mg runs at about $200 or so—check lead time on those, usually 20 days or so.

Each batch comes with a COA, it’s cGMP compliant, and the is sterile filtered and water soluble, stored at 2-8°C protected form light (shelf life is 24 months when you do it right).

Most buyers go with teh 10mg or 20mg vials for initial trials; the 5L drum is easier to handle if you’re running multiple assays, but anyway, the cost per milligram drops significantly on bulk orders.

Also, one thing you’ll notice is the powder reconstitutes cleanly—no clumping—which matters when you’re pipetting small volumes, and we usually have stock, but confirm lead time for larger quantities.

Not suited for chronic dosing studies without further validation; the molecular formula varies by peptide, so check the COA for exact specs, but for metabolic pathway research, it’s pretty much solid.
