Metabolic Longevity · 10mg × 10 vials
it tells the body to behave as if it just exercised, even when it hasn't, which is why it gets called an "exercise mimetic.
MOTS-c (Mitochondrial Open reading frame of the Twelve S rRNA-c) is a 16-amino-acid peptide encoded inside the mitochondrial 12S rRNA gene, not the cell's main nuclear DNA. This is the trick that makes it different from every other peptide on the market: it's not a synthetic mimic of a host hormone, it's a hormone the mitochondria themselves secrete to talk to the rest of the body. Identified by Pinchas Cohen's lab at USC in 2015, MOTS-c activates AMPK (the master fuel-sensing enzyme), drives GLUT4 expression in skeletal muscle, and pushes the cell toward glucose uptake, fatty acid oxidation, and mitochondrial biogenesis. In plain language: it tells the body to behave as if it just exercised, even when it hasn't, which is why it gets called an "exercise mimetic." Under metabolic stress (fasting, training, caloric deficit), MOTS-c also translocates to the nucleus and directly modulates expression of stress-response genes, which is the mechanism behind its longevity/healthspan signal.
The downstream effects line up with three real-world use cases customers ask about: insulin sensitization (the AMPK + GLUT4 axis), exercise-capacity boost (mitochondrial biogenesis + improved substrate handling), and muscle preservation during caloric deficit (AMPK-driven shift toward oxidative metabolism, plus suppression of catabolic signaling). The muscle-preservation piece is what makes it the flagship add-on for GLP-1 cuts, where rapid weight loss otherwise eats lean mass.

10 mg vial + 1 ml BAC = 10 mg/ml, so 5 mg = 0.5 ml = 50 IU on a U-100 syringe. One 10 mg kit (10 vials) at 5 mg 2x/week = ~10 weeks of research. Most first-timers won't feel anything in the first week or two beyond a vague energy uptick during workouts. The metabolic markers (insulin, glucose, lipid panel) and the body-comp signal take 2-4 weeks. If running alongside a GLP-1 cut, this is the dose where most muscle-preservation reports come from.
This is the working dose band for most users. 10 mg 3x/week = 30 mg/week, which lines up with what Swolverine and the peptide forums cite as the upper end of the typical range (5-15 mg/week split into 2-3 doses). 10 mg kit lasts ~3-4 weeks at this band, so customers stacking with a longer reta or tirz cut will usually grab the MS40 kit. Pre-workout timing is the difference between "I notice it" and "did it even do anything" per community reports.
Advanced users almost always stack MOTS-c with a GLP-1 (reta or tirz) for the muscle-preservation arm, or with NAD+ for broader mitochondrial coverage, or with CJC+Ipa for recomp. Solo MOTS-c at advanced dosing is rare. The MS40 (40 mg vial) kit covers ~13 weeks at 10 mg 3x/wk, which is the natural length of an advanced cycle.

Injection site irritation: mild, occasional - manageable with site rotation
Mild fatigue or "off" feeling first 3-7 days: reported by a minority of users, usually settles by week 2
Appetite changes: bidirectional in reports - some users describe mild appetite suppression, others describe increased hunger after training (likely AMPK-driven energy demand signaling); not consistent enough to predict per customer
Muscle cramps: rare, reported by a small number of users at the 10 mg per dose band, usually resolves with hydration + electrolytes
Sleep changes: a few users report mild sleep disruption if dosed late in the day, which is why the community standard is morning dosing
No reports of cardiovascular, GI, or systemic toxicity signals at standard doses
Route: SubQ
Injection site: abdomen or outer thigh, rotate sites
Storage: refrigerated, ~28-30 days after reconstitution
Notes: Morning dosing is the community default, ideally 30-60 min before fasted cardio or training on training days. Half-life is short (community estimates a few hours, formal human PK thin), so pre-workout timing matters more here than for long-half-life peptides like reta. On non-training days, dose can be skipped or shifted to morning fasted. Don't shake - swirl gently to mix. Use a fresh insulin syringe per draw.
