Is Human beta-nerve growth factor (beta-ngf)-(1-118)- peptide (non-covalent dimer) produced in escherichia coli nerve growth factor Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Human beta-nerve growth factor (beta-ngf)-(1-118)- peptide (non-covalent dimer) produced in escherichia coli nerve growth factor? Is Human beta-nerve growth factor (beta-ngf)-(1-118)- peptide (non-covalent dimer) produced in escherichia coli nerve growth factor safe for nursing mother and child? Does Human beta-nerve growth factor (beta-ngf)-(1-118)- peptide (non-covalent dimer) produced in escherichia coli nerve growth factor extracts into breast milk? Does Human beta-nerve growth factor (beta-ngf)-(1-118)- peptide (non-covalent dimer) produced in escherichia coli nerve growth factor has any long term or short term side effects on infants? Can Human beta-nerve growth factor (beta-ngf)-(1-118)- peptide (non-covalent dimer) produced in escherichia coli nerve growth factor influence milk supply or can Human beta-nerve growth factor (beta-ngf)-(1-118)- peptide (non-covalent dimer) produced in escherichia coli nerve growth factor decrease milk supply in lactating mothers?

Because Human beta-nerve growth factor (beta-ngf)-(1-118)- peptide (non-covalent dimer) produced in escherichia coli nerve growth factor is a large protein molecule with a molecular weight of 13,266, and absorption from the eye is limited, the amount in milk is likely to be very low and oral absorption by the infant is unlikely because it is probably destroyed in the infant's gastrointestinal tract. To substantially diminish the amount of drug that reaches the breastmilk after using eye drops, place pressure over the tear duct by the corner of the eye for 1 minute or more, then remove the excess solution with an absorbent tissue. Ophthalmic Human beta-nerve growth factor (beta-ngf)-(1-118)- peptide (non-covalent dimer) produced in escherichia coli nerve growth factor is not expected to cause any adverse effects in breastfed infants.
