Blown Away!

"I was blown away by how quickly my order from M5 Research Peptides arrived—just two days after placing it! The shipping was super fast, and the packaging was secure for my lab needs. Plus, the licensed pharmacist was incredibly available to answer my questions about peptide handling—quick responses via email made all the difference. Highly recommend for research supplies!"

Excellent Customer Service!

"Absolutely stellar customer service from M5 Research Peptides! My order got lost in transit, and before I could even reach oout Gary messaged me letting me know that there must be a courier issue and that he was reshipping with another courier! At no cost to me! The other order arrived a week later and he directed me to KEEP IT! I can't say enough about their customer service!

Ridiculously Fast Shipping!

I ordered on a Monday evening, and within 25 minutes I had a notification that my order had been prepared. Dropped off at shipping center the next morning and it was at my home Wednesday at lunch. Highly Recommend!

Way cheaper than synthesizing!

I work at a small biotech company doing cellular research on adipocytes (3T3-F442A). Ordered 30 vials of retatrutide for my company and they arrived in 2 days. 99.79% pure measured by our mass spec. Perfect for our needs as we aren’t ready to purchase our own synthesizer ($285k). Can’t recommend this company enough!

Great Sale!

I ordered 3 items during the Labor Day Sale this company had. They arrived packaged professionally within 3 days. I thought the prices were some kind of error, but after reaching out to double check, Gary ensured that they were indeed real! Cheaper than 1 item from most other places!
