MOTS-c Dosage: Complete Guide to Protocols, Reconstitution & Administration
MOTS-c dosing differs meaningfully from most other peptide protocols. It is not a daily injection or a simple weekly dose — it uses a pulsed, cyclical protocol designed to mirror the natural episodic release of MOTS-c during metabolic stress. Understanding this structure is central to getting the most from treatment.
- Typical MOTS-c doses are 5–10 mg administered 1–3 times per week via subcutaneous injection
- The most common clinical protocol is 5 mg every 5 days for 20 days (4 injections per cycle), repeated 2–4 times per year
- MOTS-c is highly unstable after reconstitution — use within 7 days for best potency; this is shorter than most other peptides
- Bacteriostatic water is required for reconstitution — sterile water degrades MOTS-c more rapidly
- Never freeze reconstituted MOTS-c; refrigerate immediately and protect from light
- Nutrition timing and diet quality directly affect how well AMPK activation translates into metabolic outcomes — low-carbohydrate or fasted states before injection may enhance effect
- All protocols are physician-supervised and personalized based on metabolic goals and individual response
Standard Dosing Protocols
MOTS-c is not taken continuously like a daily supplement. Its mechanism — AMPK activation mimicking the metabolic stress of exercise or caloric restriction — is best achieved through pulsed protocols that allow the pathway to reset between doses.
Standard protocol: 5 mg every 5 days for 20 days (4 total injections per cycle). This cycle is typically repeated 2–4 times per year based on your physician's assessment of response and goals.
Higher-dose protocol: 10 mg administered 2–3 times per week during active treatment cycles. Used for patients with more significant metabolic dysfunction or when a more aggressive initial response is clinically indicated.
Maintenance protocol: After an initial active cycle, some patients move to a lower frequency maintenance schedule — 5 mg once weekly — to sustain AMPK activation without continuous cycling. Your physician determines whether maintenance or full cycling is appropriate.

Reconstitution: Critical Stability Notes
MOTS-c is more chemically unstable after reconstitution than most other peptides. This requires strict handling.
Use bacteriostatic water only — sterile water accelerates peptide degradation. Reconstituted MOTS-c must be used within 7 days for reliable potency — this is significantly shorter than the 28-day window for TB-500 or GHK-Cu. Refrigerate immediately after mixing, protect from light, and never freeze. Never shake the vial — roll gently to dissolve.
The solution should be clear and colorless. Discard if cloudy, discolored, or if particles are visible. Because of the short stability window, vial size selection should match your planned use within the 7-day period — do not reconstitute more than you will use.
Injection Technique
MOTS-c is administered subcutaneously — into fatty tissue beneath the skin at the abdomen, outer thigh, or upper arm. The injection technique is standard: clean the site with an alcohol swab, allow to dry, pinch a fold of skin, insert at 45–90°, inject slowly, remove and apply gentle pressure without rubbing, and dispose of the needle in a sharps container.
Rotate injection sites with every dose. MOTS-c does not need to be injected near any specific target tissue — it acts systemically via AMPK activation throughout the body.

Frequently Asked Questions
Why is MOTS-c dosed in cycles rather than daily?
MOTS-c works by activating AMPK — a pathway that is naturally pulsatile and resets between activations. Continuous daily dosing can blunt receptor sensitivity. The cyclical protocol mimics how the body naturally uses MOTS-c during periods of metabolic stress.
Why is the stability window only 7 days?
MOTS-c's molecular structure is more susceptible to degradation after reconstitution than peptides like TB-500 or sermorelin. The 7-day window is not a regulatory limit — it is a potency preservation guideline. After 7 days, the peptide may still be chemically present but biological activity degrades.
Can I inject MOTS-c at any time of day?
Yes, with no hard timing requirement. However, injecting in a fasted state or before exercise may enhance AMPK activation by priming the low-energy cellular environment that MOTS-c works best in.
What if I miss a dose in my cycle?
Take the missed dose as soon as you remember and reset the 5-day interval from that point. Do not double dose. If the reconstituted solution is past 7 days, prepare a fresh vial.
