What is the half-life of Carnosine?

Carnosine has a half-life of Unknown, which is why it's typically administered As needed for optimal therapeutic effect.

How do I reconstitute Carnosine?

Add bacteriostatic water to the peptide vial slowly down the side. Typical reconstitution uses 2-3ml of water for a 5mg vial. Gently swirl, do not shake.

Research Summary

Preclinical

Carnosine has been extensively studied with hundreds of peer-reviewed publications. Human trials have shown benefits for glycemic control in prediabetic and diabetic patients, cognitive function in elderly populations, and exercise performance. A key study in the British Journal of Nutrition demonstrated that 2g/day of carnosine improved glycemic control and reduced AGE levels. Research by Hipkiss and others has established carnosine as one of the most effective natural anti-glycation agents. Its short plasma half-life (due to serum carnosinase) has led to interest in sustained-release formulations.
