Adding a me-too, because a thread of one person's experience is not much use. I had assumed I was the exception until I read this.

Bookmarking. The distinction being drawn above is the one nobody else makes. I will report back once I have actually tried it.
From the other side of the consultation, briefly.
Storage best practices for compounded storage and cold:
- Unreconstituted lyophilized powder: refrigerate (36-46°F), good for 12+ months
- Reconstituted vials: refrigerate, use within 28 days
- Pre-filled pens: refrigerate until first use, then room temp OK for 28 days
- Never freeze reconstituted peptides — ice crystals damage the protein
- Protect from light — store in original box or wrap in foil
When in doubt, refrigerate. Temperature abuse is the #1 cause of reduced potency in compounded peptides.
