In the world of experimental research, few compounds have garnered as much interest as the SS 31 peptide. Often discussed in the context of cellular energeti SS-31 (also known as Bendavia, Elamipretide, and MTP-131) is a small peptide (D-Arg- dimethyl-Tyr-Lys-Phe-NH2) that accumulates in mitochondria and scavenges cs, this molecule—frequently refer SS-31 Peptide Guide 2026: Benefits, Dosage, Protocol & r Mitochondrialtargeted peptide rapidly improves mitochondrial energetics ed to as Elamipretide, MTP-131, or Bendavia—has become a cornerstone for those focused on understanding mitochondrial health. As someone who follows the latest in laboratory research and investigative science, I have spent significant time reviewing the data surrounding this unique tetrapeptide.
Understanding the Mechanism: What is SS 31?
At its core, SS 31 is a cell-permeable aromatic cationic tetrapeptide with a molecular weight of approximately 639.8 g/mol. What makes it particularly fascinating to researchers is that it is designed to target mitochondria with high affinity.
When Feb 13, 2026 — SS-31 (elamipretide) is FDA-approved for Barth syndrome and targets mitochondria directly — How it works, off-label use for energy and observing the literature, it becomes clear that this compound functions different May 22, 2024 — Elamipretide (MTP-131, SS-31) is a cytochrome c peroxidase inhibitor. Elamipretide improves mitochondrial dysfunction, synaptic and memory ly than standard antioxidants. It specifically binds to cardiolipin, a phospholipid found in the inner mitochondrial membrane. By doing so, it helps stabilize the mitochondrial structure, which is essential for efficient energy production. Many studies note that treatment with SS 31 restores redox homeostasis, effectively helping to neutralize the conditions that lead to cellular stress.
Why Researchers Study This Peptide
The primary objective for many labs utilizing SS 31 is to explore how it can reduce mitochondrial ROS production (reactive oxygen species). High levels of ROS are often associated with cellular degradation. By modulating these pathways, the peptide acts as an antioxidant peptide SS 31, protecting the integrity of the cell's "powerhouse."
In my own review of the available materials, I’ve noted that SS 31 is a mitochondria-targeted peptide that is used to study mitochondrial function across various models. Whether it is a 10 mg vial or a SS 31 50mg supply, the consistency of the lyophilized powder is crucial for those engaged in rigorous scientific inquiry.
