There’s a second piece of validation worth pointing out: both vials came back within a tenth of a percent of each other (98.52% and 98.37%). That’s not a one-off reading.

Some lyophilized peptides are sensitive to environmental changes. Combining two solutions under different conditions can cause them to gel up or form aggregates — meaning the peptide is no longer properly dissolved and you can’t accurately dose it. None of those outcomes are what you want in a research setting where

Once a vial is opened and in active use, the preservative continues protecting the solution at room temperature across a normal use window. So what actually causes degradation?

Tesamorelin — approximately 4.5 to 6.0 Tesamorelin is a 44 amino acid GHRH analog — meaning it mimics the hormone that signals the pituitary to release growth hormone. Its solutions typically land in the 4.5 to 6.0 range. At the higher end of that window it begins approaching a more tolerable distance from tissue pH, which is why
