Peptide damage due to heat during shipment?

[FullGold]

I received my peptides and they certainly look fine but who knows. I realize these are not extremely fragile. The unconstituted powder is wrapped in aluminum foil in my freezer within a Tupperware container now. I will be using them in PCT but I was nervous about potential damage to their structure during shipment. I live in the south and it can easily reach 90-100 degrees F... Not considering the temp of my mailbox( outside). They were only in my mailbox approx. 1-2 hrs.
