Yep I have plenty of "Scientific Data" to prove my point. I have put syringes in my car to give to a friend also prescribed TRT to which the normal daily heat of the car just destroyed the syringe packaging in no time at all.. The printed labeling on BD brand syringes even starts to fade and soil. Most particularly, the glue sealing the top of the syringe packaging fails first and they come open just sitting there. My CONTROL GROUP is the ones remaining at home in my drawer in the climate controlled environment - That is - if you want to get "Scientific"...
In terms of HEAT causing the expansion of gasses and liquids in a vial this is a no brainer. The pressure increase associated with increased temperature will challenge the finest of vial sealing methods. You haphazardly lie a vial on its side, heat it up, and the liquid oil portion is going to sneak out of the stopper. Its just a piece of rubber loosely held down with a metal crimped top.
These are not "Claims". It's experience over the years of witnessing folks who kept BOTH UGL as well as PHARMA grade testosterones in their cars. It should be noted that there are so fuking many companies out there producing testosterone suspensions for injection these days, that there are a significant amount of "Pharma grade" products out there now that are very poorly contrived... I never went looking to find or prove a point. These issues came to me as questions and inquiries as to what they should do when this happens. My advice was always - "don't be a dumbass and leave in in you car - THE DIRECTIONS indicate to store at ROOM TEMPERATURE".... That in itself is ALL THE PROOF you should require...
OR.... DO you think that some jackass with a hand-held bottle cap crimper and batch of generic vials, rubber stops, and metal caps from God knows where is going to create a "Hermetically sealed" condition? Or was it that you thought that some super-cheap-fly-by-night underground garage base asshole who DOES BUY professionally manufactured vials, yet pokes them with an 18ga pin to fill them with no cap ever involved is not going to just pour out that perforated initial fill-hole created when cramming his cheap ass pot cooked solution in there when the car heat is applied...
There is no need to get "Scientific" on this matter. Its just a statement of WHAT IS...
And if you are referring to my description of the action of the "Plasticizers" involved.. Just research the (7) primary grades of plastics and the common denominator you will find is that the softer the plastic, the nastier it is. Molecularly speaking. Even Kentwood water jugs are IRONICALLY COMPRISED of BPA's, due to if they were not,,,, the plastic jug would be too brittle and crack all the time during normal delivery and handling... Ever seen a milk jug SPLIT? They dont stretch. That's because they are more brittle as a matter of chemical safety...
