Mass spectrometry for peptide identity verification — March 2026

Reading this thread on Mass spectrometry for hits close to home. Dad of 2 checking in — I started at 281 lbs and felt like I would tried everything.

7 months on tirz and I am a different person. Not just the 56 lbs lost — my energy, my mood, my relationship with food. All transformed.

If you are on the fence about Mass spectrometry — take the leap. It was the best health decision I have ever made. ❤️

Agreed. My doctor said the same thing about Mass spectrometry.
