Agreed, and light exposure is a real but secondary factor. Keep it in the carton; do not build a protocol around it.

Bookmarking. The distinction being drawn above is the one nobody else makes. Taking it to my next appointment.

Adding the clinical framing, because it changes how the question reads. The mechanism and the magnitude are separate questions. Agreeing that something happens says nothing about whether it happens enough to act on.

Mine went the same way, slower. Posting only so the count is not one.

Adding the part of the answer the thread has not reached. The distinction that matters is unopened versus in use. Unopened vials are stable refrigerated for their labelled shelf life and tolerate a limited excursion to room temperature. Once reconstituted, the clock is much shorter and is set by the preservative rather than by the peptide — bacteriostatic water's benzyl alcohol is what buys you multiple draws over weeks. Sterile water has no preservative and turns a multi-dose vial into a single-use one.

I would rather be corrected than agreed with, if it comes to it.
