About these numbers

The example mixes a 50 mg vial with 1 mL of water for 50 mg/mL, where a 40 mg dose is 0.8 mL, or 80 units. The 40 mg once-daily figure comes from the approved Barth syndrome product and the mitochondrial myopathy trials.

SS-31 (elamipretide) is approved only for the ultra-rare Barth syndrome; other uses are off-label or investigational. Independently sourced material is not tested to the same standard as the approved product.
