US-Based Biosimilar Supply Chain Redundancy for Commercial Distributors
Partner with us
Effective Q1 2027, our company, formerly known as Zeptide Pharma (and operating under the name Tirzepatide Pharma) will officially rebrand as MayMag Biologics. This strategic transition establishes a distinct corporate identity and eliminates market confusion between our company and the active pharmaceutical ingredient (API) generically known as Tirzepatide.
