Pfizer

Pfizer products are protected by high-level pharmaceutical security features. Authentic Pfizer Genotropin typically comes in specialized delivery systems like the GoQuick pen or MiniQuick. You can verify the product by checking the lot number and expiration date against Pfizer's official global database or through authorized pharmaceutical tracking systems available in your region.

Yes, Pfizer Genotropin is the gold standard for pharmaceutical-grade Somatropin. Unlike underground or research labs, Pfizer operates under strict FDA and EMA oversight. Every batch is produced in a sterile, clinical environment following cGMP (current Good Manufacturing Practice), ensuring 100% purity and biological identity.

Pfizer utilizes recombinant DNA technology with highly refined purification processes. Their growth hormone products maintain a purity that exceeds 99.9%. This eliminates the risk of ghost proteins or bacterial residues, which are common in lower-quality brands and can cause immune responses in research models.

Pfizer's Genotropin utilizes a unique two-chamber cartridge system. One chamber contains the lyophilized (freeze-dried) powder and the other contains the diluent. This separation ensures the hormone remains stable for a long period without degradation until the exact moment of reconstitution.

To ensure the integrity of Pfizer pharmaceutical products:

• Before Reconstitution: Must be stored in a refrigerator between 2°C and 8°C.
• After Reconstitution: Depending on the specific delivery system (like the GoQuick pen), it can remain stable in the refrigerator for up to 28 days. Always avoid freezing as it destroys the delicate protein structure.
