Having BAC water is a newbie right of passage! Honestly caught me off guard the first time and my BPC foamed up like crazy. Had the same worries as you but it should be fine. You’ll find conflicting information online about it but I’ve settled that the peptides aren’t as delicate as we may think. Heck I even shake them when they’re being finicky during recon and are still working as expected.
Good practice to wipe with alcohol before and after every use. Has it ruined the peptide? Is a colony of brain eating bacteria being introduced? Unlikely
Pointers from me would to give the time for the pep to do it’s magic. I see a lot of people wanting to titrate up super quick with reta when it’s designed to have 4 week escalations. Should you start at 2mg and follow trial dosing? Sure, your results should be in line with what the data shows. Do you wanna start lower and go slower with titrations? Sure! Find what works best for you.
Goodluck!
