It's not the highest purity on paper—that 90% threshold means you're losing about 10% to residual salts or truncated fragments, so if your IC50 work requires 98% or better, this batch isn't it.

But for most exploratory binding studies or preliminary in vivo dosing, 90% active peptide is actually fine; we've run it with 5mg or 10mg doses per vial and response curves are consistent enough for early-stage decisions.


Sample tier runs about $180 for a gram, mid-tier gets you to $140/gram at 10 grams, and bulk at 100 grams drops to around $95/gram—prices are base on current raw materail costs, roughly adjusted every quarter or so.

We usually have stock, but confirm lead time if you need more than 500 grams at once; teh paper packaing is standerd (not ideal for long-term damp storage), so plan to transfer to airtight vials within 20 days or so.

Also, the CAS is 2381089-83-2, and what it does is suppress appetite through GLP-1 and GIP receptor agonism—better than reagent-grade semaglutide for metabolic studies because of the dual action, but not recommended for acute toxicity panels where absolute purity is critical.
It means that over 90% of the powder by weight is the retatrutide peptide itself, not binders or impurities. That's a purity floor — actual lots often test higher, but we guarantee at least 90%.
Yes, we can share a COA for this retatrutide batch upon request. It covers the >90% active content, identity, and any residual solvents. Just ask your sales contact.
Our standard MOQ is 10 grams for wholesale, but we do offer smaller sample sizes (e.g., 1 gram) for research validation. Minimum for a trial is typically 1 gram.
Keep it in a cool, dry place — room temperature is fine if it's sealed and away from moisture and direct sun. A desiccator or fridge in a sealed container works best for long-term storage.
Yes, we can customize packaging — think smaller vials, specific labels, or different paper materials. Just let us know your requirements when you place the order.
