Tirz kept its effectiveness nicely over time. Seeing interest in checking this is welcome. I had questions about Mots but now they're answered.
I saw this video on peptide stability first. I really wish someone would run a study retesting these two peptides after long-term freezer storage. I would like to see any study on a similar peptide because the video shows that different structures can have different stability. Second, I question how this study lines up with what the original maker and compounders say. The maker lists a two-year shelf life while many compounders extended their dates to about a year. Could different sources end up with different stability even if the molecule is the same? Plenty of people using compounded versions are not seeing the drop in results you would expect if potency halved. Maybe it comes down to using plain bacteriostatic water instead of phenol or other stabilizers, or maybe the vials sat under bright light. I would like to hear from people who know more about this. Will the results change anyone's plans?
