Ordered for a small research project. Documentation was thorough — the batch COA listed everything I needed and matched the vial label. Will source from again.

Reconstituted clean at 5 mg/mL. No precipitate, no cloudiness. Purity claim looks accurate.

Switched over after some inconsistency from another supplier — the difference in vial quality is noticeable. Lyophilized cake is dense and uniform, and the batch documentation actually matches what's in the box.

Product itself was as described and the documentation matched. Shipping took an extra day past the estimate but tracking was accurate the whole way.

Honestly didn't expect it to be this clean. Tried a few suppliers over the past year and this is the best so far. Will be back.

Quality is great, no issue with the product. Only knock is the outer box looked a little beat up — everything inside was sealed and intact though.
