Testosterone vials are supposed to be protected from light to avoid degradation.
Is it sunlight (with UVs) or any light?
Obviously there will be light when you administer tt, so I was wondering if this is something to be careful about even when you inject (like to not let the vial on outside his storage place too long)?
I would think this is important since my vials are completely transparent.
I don’t think it’s a problem. Just don’t store your meds in direct sunlight. I keep mine in a plastic tool box in the corner of the room. A drawer will be fine too. Degradation takes place over weeks/months not a day or two or the few minutes you have olit out to inject.
