Selective, Not Sparse : Certain critical data must always be collected, e.g., serious adverse events (SAEs), AEs leading to study drug discontinuation, and AEs of special interest
Greying or Whitening of Hair: The premature greying of hair may be associated with low B12 or D

Its not contraindicated, but needs close monitoring
Together, these approaches make it easier to turn potential regenerative peptide benefits into practical changes you can feel in daily life
