Wholesale TB-500 (CAS 885340-08-9) | Pharmaceutical Grade Peptide

We've structured the pricing so that even on a sample-level order of a single box it's pretty competitive, but the real savings kick in once you move to mid-tier quantities like 5 boxes or so, where the per-vial cost drops noticeably, and for bulk orders of 50 boxes or more we're looking at roughly 30-40% less than what you'd pay for smaller lots.

The lyophilized powder (white, as you'd expect) runs at ≥99% by HPLC, which matters because impurities can compromise results in longer-term studies—nobody wants to chase a false signal—and it stays stable for the full 2-year shelf life when you keep it at -20°C, though we usually have stock and can ship within a week unless demand spikes.

Actually, one thing most buyers don't think to ask is that the 20mg vial format is easier to reconstitute accurately for multiple doses, since the larger mass dissolves more evenly than the 5mg vials, which can leave a tiny residue if you're not careful with your solvent volume.

It's not ideal for oral administration obviously—this is an injection-grade peptide, so you'll be reconstituting with bacteriostatic water or sterile saline anyway, and the pharmaceutical grade simply means tighter tolerance than research-grade on endotoxin levels, though we don't routinely test below 1 ppm unless you request it.

5, we use liquid nitrogen at -196°C during teh freeze-drying step to lock in activity, but honestly the 5mg vials are a bit more delicate during shiping (check the stopper seal on arrival), and for bulk buyers we recommend ordering 10mg vials instead if you're handling multiple reconstitutions across a month or two.

Anyway, on packaing it's 10 regardless of dosage strength, so a box of 20mg gives you 200mg total peptide, which is often enough for a single cycle depending on your dosing schedule—roughly 2-4 grams is the typical range for most researchers we supply.
