Lyophilized Peps + Heat in Shipping Truck
-
I jumped onto the peptide bandwagon about 6mo ago and it’s been TREMENDOUSLY helpful so far. I found a vendor on here that actually ships from inside my state (KS). Recently I switched up vendors to try to diversify a bit. I thought Mile-High-Compounds was from CO, but the tracking info says that it shipped from Tempe, AZ… which has a high of 105°F today. I work at a shipping/delivery company and I know trucks become ovens. TLDR- how torched and worthless are peptide vials sent in this heat? I lucked out getting into peps during winter, so should I just wait til cooler temps again? I was actually trying to plan the order around a cooler-temp window between CO & KS… hopefully they still turn out ok. I’ll probably just stick with that first company I lucked out with in my state. Anyone else have a take on peptide degradation in the summer heat during shipping?
@Jake_PepTron Great question! I don't know 100% at what temperature peptides start to quickly degrade, but I do know this 100% - Lyophilized peptides are WAY more hardy than you think...and what you are led to believe. BUT, and it's a BIG but, like I said, I do not have the data on super high temps and peptide degradation. But Lyophilized peptides are hardy.

Direct sunlight is MUCH more damaging to peptides than heat! Photons degrade peptides and break the covalent bonds rendering the peptides useless after just days of direct exposure. According to a study in the Journal of Peptide Science, UV light exposure for just 48 hours can reduce the potency of certain lyophilized peptides by 15% to 20%. Heat takes weeks or months to cause that level of damage to freeze dried lyophilized peptides. I think it would do damage, but not much, if the peptides were in a shipping container in 110 degree Fahrenheit heat for a week or more. I get that after reading that journal of peptide science article reporting. https://adonyxbio.com/the-art-and-science-of-storing-lyophilized-peptides-a-deep-dive-into-stability-and-longevity/ and the reports below.

AND THIS ONE HITS THE HEAT THRESHOLD almost perfectly.
"lyophilized peptides easily tolerate brief, transient heat exposures up to 40°C–45°C (104°F–113°F) during transit with no measurable loss in purity. Thermal energy alone simply lacks the power to easily break covalent bonds in a completely dry, glassy matrix."

@Eleanor HAHA! That's pretty funny.
And totally true! Example: Iraq in July 138 F, Ft Benning GA in July 98 w/90% humidity. MUCH hotter at Benning!! Much more miserable! Not even close! Lol -
