Plain-language summary: Elamipretide, also known as SS-31 in research literature, became the active ingredient in an FDA-approved product in 2025 for a specific rare-disease indication.
What Is SS-31 (Elamipretide)?
FDA granted accelerated approval to Forzinity (elamipretide) to improve muscle strength in patients with Barth syndrome weighing at least 30 kilograms. Approval is product- and indication-specific.
Research and Regulatory Context
The approval relied on a small rare-disease evidence base and requires confirmatory research. It does not validate unapproved research vials or claims for unrelated mitochondrial, aging, exercise, or wellness uses.
Regulatory status and evidence can be specific to a chemical form, formulation, route, manufacturer, and intended use. A similarly named research material should not be assumed equivalent to a studied or approved product.
Using the Concentration Calculator
Selecting SS-31 (Elamipretide) labels the calculation and saved report. The tool divides the entered vial amount by the entered BAC water volume and performs unit conversion when requested. It does not choose a target amount or create a protocol.
Evidence and Safety Limits
The calculator cannot determine identity, purity, sterility, stability, contamination, authenticity, or suitability. Laboratory findings, animal studies, small trials, testimonials, and marketing claims do not carry the same evidentiary weight as large controlled clinical trials and product-specific regulatory review.
Frequently Asked Questions
Is SS-31 (Elamipretide) FDA approved?
The active ingredient appears in a specific FDA-approved prescription product. Approval applies only to that product’s formulation, labeling, indication, and manufacturing controls.
Why is it included in the calculator?
The name organizes generic concentration math, saved calculations, QR reports, and research context. Inclusion is not an endorsement or recommendation.
Does this page provide a dose or injection instruction?
No. The calculator only processes user-entered quantities and liquid volume. It does not determine an appropriate amount, schedule, route, or use.
