Great customer service from before the purchase to well after. I’ve taken Tirzepatide from a compounding pharmacy from December 2024- June 2025, and just took my first dose of the Certified Peptides Tirzepatide at the end of June. The Certified Peptides version had a noticeably different impact on my hunger/food noise and nearly took it completely away at the same dose I was previously taking. I have to force myself to eat bc I have zero appetite. I am completely blown away, and considering stepping my dosage back down from 50 units to 37.5 as this appears to be a better product than I was taking for the last 6 months. I couldn’t be happier. If you’re on the fence about trying Certified Peptides, don’t be. You’re just cheating yourself out of time.
