100 days wouldn't bother me but that is my opinion - depends on the insert and UGL is not pharmacy with an insert guaranteeing temp controls.How long is it fine to sit around for? Let’s say you bought a 270 iu for example and you only wanted to use 2.7 iu daily that would mean it would be around for 100 days, if you only mix one vial at a time and keep the powder in the fridge is that to long for it to sit around ?
And once mixed if kept cool how long you think you can keep the vial around?
I bought 7 kits once (script) and took them all out and put them in a container and put them at the back of the fridge so they were just above freezing but they travelled in a van for a good part of the trip here to a post office box sitting in the summer in 30 degree heat which isn't good hence watching the tracking and grabbing it as soon as possible.
I am not sure of the exact number of days and the medical insert just said 30 days at room temp is fine and then refrigerate and keep at the back of the fridge just above freezing until mixed and used. Especially, with Serostim once mixed - only insert that I read that indicated it did not have to be kept cool from day 1 (was good for the 30 days).
Think of the number of hands and travel time in the summer in the blistering heat unless it is script and delivered from a pharmacy to your house in a cooler. That is what TRT clinics do.
They still work but the best HGH (not always but as a general rule) is the HGH that is handled the least, kept as cool as possible, but that isn't possible in most situations. You aren't going to tell CP who takes 7-14 days to get it to your house it is HGH and it has to be shipped cold.
I highly doubt fragile peptides, HGH, that is made in bulk - regardless how good the UGL is (I could be wrong) is then moved over to a huge refrigerator until shipped.
I had script HGH in my fridge for over 100 days and never gave it a second thought. I asked two docs who are friends and their comment was it may lose some potency but should still be fine as time passes. Keep in mind, I am no expert and can't guarantee this. I would ask the rep that you are dealing with if they have any 'guidelines' if an UGL product. Sorry for the ambiguity.
