I can't say enough about Certified! I had an issue with a peptide and reached out to the company. This was during Not only Christmas and New Years, but they were going through a catastrophic flood and weather event. Three strikes going against them and they performed flawlessly, Literally. We have a 3 hour time difference and whenever i e-mailed Jason he got back to me in MINUTES. They have a ton of 5 star reviews and now I know why! Keep it up, you guys/girls are the best!
