I was skeptical at first, but after consistent use, Ive noticed a significant reduction in pigmentation
Chowers I, Wong R, Dentchev T, Farkas RH, Iacovelli J, Gunatilaka TL et al (2006) The iron carrier transferrin is upregulated in retinas from patients with age-related macular degeneration

The basic formula Concentration (mg/mL) = Total peptide (mg) Water volume (mL) For a 70mg vial with 3mL water: 70 3 = 23.33 mg/mL Volume to draw (mL) = Desired dose (mg) Concentration (mg/mL) For 2.33mg dose at 23.33 mg/mL: 2.33 23.33 = 0.10mL = 10 units on an insulin syringe Common vial sizes and calculations 42mg vial with 1.8mL water: Concentration: 23.33 mg/mL Standard dose (2.33mg): 10 units Conservative dose (1.165mg): 5 units Vial provides approximately 18 doses at standard protocol 70mg vial with 3mL water: Concentration: 23.33 mg/mL Standard dose (2.33mg): 10 units Conservative dose (1.165mg): 5 units Vial provides approximately 30 doses at standard protocol 70mg vial with 2mL water (higher concentration): Concentration: 35 mg/mL Standard dose (2.33mg): 6.7 units (round to 7) Conservative dose (1.165mg): 3.3 units (round to 3) Smaller volumes make precise measurement more difficult The SeekPeptides peptide calculator automates these calculations for any vial size and desired dose
