95% purity’s not the top shelf you see from some premium supliers, but it holds up fine for most screening work—and the cost difference versus 98% is actually pretty huge for bulk buys.
We’ve done runs with modifications like acetylation or biotinylation, and you’ll get a solid COA for each batch—HPLC and MS data included—so you can verify the sequence without chasing documentation.
Custom MW is what this plays on, and our company can tailor chain length pretty much to your spec; teh 2-4 week lead time (check it, since it can stretch during peak) beats scrambling for form bigger vendors.

1mg MOQ is generous, but most buyers ordering bulk go for 100mg or so—still, we’ll ship 1mg if you need a test run for solubility (it dissolves in water or organic solvents before scaling up).
It’s not suited for in vivo work unless you’ve verified it yourself—strictly for research use, and storage at -20°C isn’t negotiable; we’ve had vials degrade in about three weeks at room temp, so keep it cold.
Price per milligram drops sharply after 50mg or so, and dilevery times are usually consistent—unless you request an uncommon modification, which adds maybe a week.
Yes, our minimum order is just 1mg, so you can start small for initial testing or pilot studies without committing to a large batch.
We provide a Certificate of Analysis (COA) for every order, detailing purity results from HPLC and MS analysis.
Standard lead time is 2-4 weeks, depending on the sequence length and modifications requested.
Yes, we offer modifications like acetylation, amidation, and biotin labeling via our SPPS/Fmoc chemistry platform.
Store the peptide at -20°C immediately after receipt to maintain stability and purity.
A fantastic experience overall with the peptide bulk order service. The delivery was incredibly fast and reliable, arriving well ahead of schedule, which was a pleasant surprise. The quality of the peptides appears excellent, with no issues noted upon initial inspection. Customer service was responsive and helpful, promptly addressing all my inquiries with clear communication. Highly recommended for anyone needing professional peptide production services.
