Vitamin C in the morning, copper peptides at night gives you both without the conflict
Pregnancy and breastfeeding are also contraindicated due to a lack of safety data for systemic use in these populations
Using 2mL gives you 2.5mg/mL concentration (20 IU = 0.5mg), while 2.5mL gives 2mg/mL (25 IU = 0.5mg)
