Peptide Sciences User Review: Great Product, Great Customer Service
-
5.00/5 | Reviewed November 14, 2025Peptide: GLP3-R
I've used PS for years. I have always received quality and effective Peptides (and molecules.) Price may be a little higher, but for the research, quality and USA produced product, it's worth it to me. I've done full stacks from Reta to IGF to Tessa/Imp/CJC, AOD, etc...and have only found 1 time where a vial crystalized or gelled, (product of user error?) and they replaced/refunded without any questions other than wanting info (Batch, date, etc...) to make sure that it was a single issue or Batch issue.
