    Attribute TUDCA MOTS-c
    Category Liver Support Longevity & Cellular Health
    Research Stage Preclinical Preclinical
    Mechanism of Action TUDCA's mechanism of action operates through several distinct but overlapping pathways, making it unusual among bile acid therapeutics in having multiple pharmacologically meaningful modes of activity beyond simple bile-acid replacement. Pathway 1: Bile acid… 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 TUDCA has an exceptionally favorable safety profile with decades of clinical use at the traditional cholestasis doses and accumulating safety data at the higher doses used in ALS trials. Common side effects (5-15% at typical doses 250-1,000 mg/day): - Mild… 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

    Frequently asked

    What's the difference between TUDCA and MOTS-c?

    TUDCA is a liver support that tudca's mechanism of action operates through several distinct but overlapping pathways, making it unusual among bile acid therapeutics in having multiple pharmacologically…. 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, TUDCA or MOTS-c?

    TUDCA 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.

    Which is cheaper, TUDCA or MOTS-c?

    Lowest listed price on BodyHackGuide: TUDCA from $79.99, MOTS-c from $44.99. Prices are pulled from the vendor listings tracked on BHG and change frequently. See the compare tables on each compound page for the current set of offers.

    Can you stack TUDCA and MOTS-c?

    Stacking depends on mechanism overlap, safety profile, and goals. TUDCA and MOTS-c should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data. Use the BodyHackGuide stack builder for a structured review before combining research compounds.
