The thread concludes frost limited to the canister is not a problem and the vials remain usable. Participants distinguish between frost in the outer container versus inside the actual vials, noting that small amounts in vials can result from incomplete moisture removal during processing and are typically not serious. A large quantity inside a vial would be more concerning. The original poster confirmed the frost was only in the canister and received reassurance.
What this discussion establishesNothing here is advice.
I pulled a vial of glow and bpc 157 out of storage and spotted light frost on the inside of the canister. There are a couple desiccant packs in there, yet frost still shows up on the wall. Think the vials are still good to go?
Don't know the answer myself but want to read what people say about it.
When moisture appears confined to the outer holder, things look okay. But if it shows up inside the glass container, the quantity matters. The freeze drying step can leave a bit of water behind at times. Total dryness is the usual case, while light ice near the upper part of the container rarely signals trouble, though bigger traces point to possible issues with that container. Just my take.
Yeah I'm wondering whether it's inside the small bottle itself or instead the outer case around that bottle.
The bottles seem okay when checked from right within the holder.
I wouldn't see any problem here unless heavy residue had damaged how the container closes up.
