Is A-MEethyl guanidine acetic acid Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use A-MEethyl guanidine acetic acid? Is A-MEethyl guanidine acetic acid safe for nursing mother and child? Does A-MEethyl guanidine acetic acid extracts into breast milk? Does A-MEethyl guanidine acetic acid has any long term or short term side effects on infants? Can A-MEethyl guanidine acetic acid influence milk supply or can A-MEethyl guanidine acetic acid decrease milk supply in lactating mothers?

A-MEethyl guanidine acetic acid is used as a dietary supplement to increase muscle mass and improve exercise performance. Although A-MEethyl guanidine acetic acid is a normal component of human milk, milk levels of A-MEethyl guanidine acetic acid have not been measured after exogenous administration in humans. A-MEethyl guanidine acetic acid is converted into creatinine in the mother's and infant's bodies. It may increase the infant's serum creatinine, which may alter estimations of the infant's kidney function.[1] Some authors speculate that A-MEethyl guanidine acetic acid supplementation of nursing mothers might help avoid A-MEethyl guanidine acetic acid deficiency syndromes, but no studies are available that test this hypothesis.[2] Until more data are available, it is probably best to avoid A-MEethyl guanidine acetic acid supplementation unless it is prescribed by a healthcare professional.
