Turns Out Temperature Matters More Than We Thought

Here's something we learned the hard way: peptides are picky about temperature.

We had a customer last year who couldn't figure out why results were inconsistent. Same peptide, same dosage, same protocol. But something was off.

Turns out the shipment had sat on a loading dock for six hours in July heat before delivery. By the time it reached the lab, the degradation had already started.

We're not telling this story to blame anyone. Stuff happens. But it reminded us—and now we remind everyone—that cold chain matters.

Peptides are delicate. Heat speeds up hydrolysis. Freeze-thaw cycles cause aggregation. The stuff works best when it's handled carefully from the moment it's made to the moment it's used.

We've started including temperature logs with every shipment. And we always tell new customers: when it arrives, check it, chill it, use it right.
