A study from The Netherlands (Riphagen, 2020) found that after 8.5 years of follow-up of an older cohort (median baseline age=65), a doubling of baseline MMA levels was associated with an increased risk of mortality (HR 11.48, CI 3.3239.64)

Even though peptide therapy clears your system within hours, the tissue repair and signaling restoration it initiates continues well beyond a single dose
Conclusion This study demonstrated that serum vitamin B12 levels were negatively associated with testosterone concentrations in the female population, whereas no significant association was observed in males
