dihexa injection vs oral Dosage Guide: How Much Should You Take? (2026) My research on Dihexa #1:

B12 Shots Vitamin B12 is a water-soluble B vitamin found in some foods

Hair transplant surgery: Suitable for severe or patterned baldness to restore density by transplanting follicles

For a 10 mg lyophilized vial: At 2.5 mg/week: 4 weeks of doses (perfectly matches the 28-day stability window) At 5 mg/week: 2 weeks of doses (well within stability limits) For a 30 mg lyophilized vial: At 2.5 mg/week: 12 weeks of doses (far exceeds 28-day window, significant waste) At 5 mg/week: 6 weeks (exceeds window by 2 weeks) At 7.5 mg/week: 4 weeks (perfect alignment) At 10 mg/week: 3 weeks (fully within stability limits) The reconstitution volume you choose affects how easy it is to measure each dose but does not change these timelines

It comes from: mislabeled vials, impurities, non-sterile preparation, poor storage stability, or dosing errors
