I can’t say enough good things about this. It’s literally changed my life. I’ve tried other peptide companies before. The customer service with certified peptide and Jason exclusively has been outstanding. Sometimes I have the silliest questions at the oddest hours, and I’m always treated with respect and with a quick response. I’ve had phenomenal results with the product and The shipping is faster than I could even hope for! Literally it comes before you’re even wondering where it’s at!!! You will not be disappointed!
