TB-500 Peptide 99% Purity CAS 885340-08-9 for Research Use

If you've been dealing with peptides that arrive inconsistent or barely hit that advertised purity, you already know the headache. This one comes in at ≥99%, and the vial seams are clean—no oxidation marks around the neck (usually 2-4 weeks for those to show if storage was sloppy on our end).

CAS is 885340-08-9, molecular weight 889.02, and it's a 38-carbon chain with ten nitrogens—pretty standard for this class. We test every batch with HPLC and provide a COA on request; the 99% isn't a one-time number but a spec we hold batch-to-batch within about 0.2% variance. Most buyers go with the 10mg vial for regular runs, though 5mg and 20mg are availble.

It's not suited for long-term room-temperture storage—you'll want -20°C, dry conditions, and that gives you a 24-month shelf life if sealed properly. One thing you might not think to ask: after reconstitution, we typically see stability drop around 15-20 days or so, so plan your dosing window accordingly.

Also, we do custom packging on larger MOQs—say, 50 boxes or more—and can adjust vial fill amounts. Lead time is usually 10-15 business days for standard orders, but we usually have stock, so confirm lead time before scheduling; delays happen mainly during Chinese holidays. Payment is via T/T or wire transfer for first orders, and we ship with cold packs and thermal liners as standdard.

Basically, it's a tight-tolerance peptide with decent consistency across lots, and documentation covers what procurement needs for audit trails without extra back-and-forth. You'll get an SDS and COA with the shipment, and teh powder is easier to handle than some others we've run—less static cling in dry lab conditions.
