You're probably finding that sourcing consistent peptide material for retatrutide trials is a headache — one batch runs fine, next throws your results off completely, and that's a problem we see all the time.
What we do is run every batch through HPLC and MS verification before it ships, so you're not guessing about purity or identity when you're in the middle of a study, and we keep the same tight specs across lots.
≥99% purity, MW at 1007.19, and it's soluble in water which makes reconstitution straightforward for most protocols — storage is 2-8°C in a dry enviroment, shelf life is 24 months or so.
Basically, we ship it as a white to off-white powder in 1g, 5g, or 10g packs, but custom quantities are fine if you need something else, and we usually have stock on the 5g.
It's not ideal for anything outside research use, obviously, and the CAS is 50-56-6 if you need to cross-check against your reference standdard.
One thing that catches people off guard is that teh powder is hygroscopic, so don't leave it out longer than necesary when weighing — we always include that note with the COA.
We can definitely accommodate custom quantities below 1g if needed — just let us know your exact requirement. Our standard packaging starts at 1g, but we're flexible for research orders.
Standard orders ship within 5-7 business days, and custom quantities typically add 2-3 days for packaging. Larger custom batches may take a bit longer, but we'll confirm timing when you place the order.
Yes, every shipment includes the HPLC, MS, and NMR verification reports for that specific batch. If you need them in advance or have a preferred format, just ask and we'll send them over.
It's best to keep it refrigerated at 2-8°C whenever possible, but short-term exposure at room temperature during transit or handling is fine. Just make sure it's stored properly once it arrives to maintain the full 24-month shelf life.
We supply it as a dry powder only — that's the standard for research-grade peptide raw material. Customization is available for the quantity and packaging, but we don't alter the compound itself or provide pre-dissolved solutions.
Came across this service while searching for pharmaceutical compounds, and I must say the delivery was incredibly fast. The quality of the items received seems top-notch, exactly as described. Customer support was very responsive and helpful throughout the process. Overall, a smooth and reliable experience that I'd recommend to others.
