Contamination, mis-dosing, and degradation are real practical risks separate from the molecule itself
While each peptide has established research profiles, the blend allows investigation of potential additive or synergistic effectswhether combining different repair mechanisms produces outcomes different from either peptide alone
Reported biochemical potency against human NNMT is in the low-micromolar range with cellular EC values in the low-micromolar range for suppression of 1-MNA and lipogenesis, with selectivity over related methyltransferases and NAD-salvage enzymes [1,6,7]

As earlier pointed out, vitamin B12 benefits the body in different ways and skin is not an exception, but how does Vitamin B12 improve skin health
It is detectable on a drug test, so you run the risk of testing positive if you use it
