Peptide quality?

[picklejogger]

Feels like the last few months have brought a real drop in quality. The higher strength batch I picked up last month doesn't compare at all to the lower strength one from five months back. Quality's fallen off noticeably. Has anyone else run into the same thing?

Planning to try a particular peptide next based on some research I came across. Also currently using reta, though results haven't shown up yet.

How does anyone actually verify which supplement brands are trustworthy? None of it is regulated. Feels just as unpredictable as sourcing peptides honestly.
