Resolution therefore closed the doors unevenly, and the asymmetry follows from the bulks lists.

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.

Freezing is the one to avoid, and freeze-thaw more so.

Thank you for spelling out the reasoning rather than just the conclusion. Sending this to two other people who asked me the same thing last week.

Storage question about storage and cold: my pen was left out of the fridge for 18 hours. Is it still good?

Per the manufacturer, both Ozempic and Wegovy pens can be stored at room temp (up to 86°F) for up to 28 days after first use. So yes, it should be fine as long as it wasn't exposed to extreme heat.

Adding the numbers, since they settle part of this. Keep the original post as written when you update it, and add the correction underneath. An edited-away mistake is invisible to the next person who makes it.
