Unlike molecules with… | A New Class of Signaling Molecule MOTS-c belongs to the mitochondrial-derived peptides (MDPs) - a class of small peptides encoded within mitochondrial DNA open reading frames that were historically thought to encode only ribosomal RNAs. The known MDPs include:… | | Half-Life | — | ~4–6 hours | | Typical Dose Range | — | 5,000–10,000 mcg (5–10 mg) per injection | | Dosing Frequency | — | 2-3 times per week | | Administration | — | Subcutaneous, Intramuscular | | Side Effects | Astaxanthin at supplementation doses (4-12 mg/day) has one of the most favorable safety profiles among dietary supplements. Human trials at doses up to 40 mg/day for up to 4 months have not identified significant adverse effects. The FDA has granted GRAS… | Reported Effects (limited human data) - Injection site reactions — Mild erythema, transient itching at SC injection site. Site rotation minimizes. Probably the single most reported issue. - Transient fatigue — Some users report mild fatigue in the first week… | | Molecular Weight | — | 2174 Da | | Common Vial Sizes | — | 5mg, 10mg | ## Price History 5 data points - OF - BM - Half Nattys - Ion Peptide - Disguised Alpha - BHG Labs ### Astaxanthin: potential benefits - No structured benefit list published. ### MOTS-c: potential benefits - Insulin sensitivity - Exercise mimicry - Metabolic health - Anti-aging - Fat oxidation - Longevity ## Frequently asked ### What's the difference between Astaxanthin and MOTS-c? Astaxanthin is a carotenoid that astaxanthin's mechanism of action centers on its exceptional antioxidant and membrane-stabilizing activity, supplemented by anti-inflammatory, immunomodulatory, and signaling…. MOTS-c is a longevity & cellular health that a new class of signaling molecule mots-c belongs to the mitochondrial-derived peptides (mdps) - a class of small peptides encoded within mitochondrial dna open reading frames that…. The two differ in mechanism, half-life (not reported vs ~4–6 hours), and typical dose range. ### Which has the longer half-life, Astaxanthin or MOTS-c? Astaxanthin has a half-life of not reported. MOTS-c has a half-life of ~4–6 hours. Longer half-lives generally mean less frequent dosing but slower on/off kinetics. ### Can you stack Astaxanthin and MOTS-c? Stacking depends on mechanism overlap, safety profile, and goals. Astaxanthin and MOTS-c should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data.
