Factory Direct QSC Tirzepatide - Pharmaceutical Grade Peptides

We typically run batches at 99% purity by HPLC, and teh CAS is 446036-97-1 — that is what you're actually getting, not a reconstituted solution. Most labs we work with order in 10-vial kits, and the common doses per vial are 5mg, 10mg, 15mg, 20mg, or 30mg depending on your protocol.

Bulk pricing kicks in around 50 kits or so, but we generally ask you to confirm lead time before quoting because some concentrations move faster than others. The 10mg vials are the most popular, actually — we stock those more consistently than the 5mg or 30mg, which might take an extra 3-5 days if we're low.

It's not ideal for in vivo work beyond rodent models, and we don't recommend it for anything involving human use — that's not what it's tested for, and frankly the purity tolerances aren't validated for that. Buyers often ask about reconstitution buffers, and we usually point them to sterile water or bacteriostatic water (check your own protocol), but we don't supply those.

Storage is straightforward — keep it in a cool, dry place away from light, and it'll hold stability for 2 years or so form manufactyre. One thing people don't always think about is that the powder can absorb moisture if you open it in a humid enviornment, so we recommend reconstituting within 30 minutes of vial puncture.

Every batch comes with a COA, and our company can share HPLC trace if you need it for your records. The pharmaceutical grade designation just means tighter impurity specs than research-grade — a little better for, but you'll pay maybe 15-20% more per mg than standard.
