MOTS-C Dosage Guide

Standard Dosage Protocol

Most common protocol: 10mg (5mg per injection twice weekly) or 15mg weekly (5mg three times weekly). This produces noticeable metabolic improvements in 4-6 weeks. The dosing is reconstituted from lyophilized powder: typical vials contain 5mg requiring reconstitution with sterile water or bacteriostatic saline.

Injections are subcutaneous (under skin), similar to insulin. Injection sites rotate: abdomen, thighs, shoulders. No intramuscular injection needed. Insulin syringes (1cc/100 unit) or peptide-specific syringes make accurate dosing simple. The small injection volume makes site rotation comfortable.

Low-Dose Protocol (Beginners)

5-10mg weekly total (2.5-5mg twice weekly) produces 60-70% of standard-dose results with even better tolerability. This 'starter' protocol allows assessment of individual response before committing to higher doses. Many users find 10mg weekly produces sufficient results: 2-3% improvement in glucose control, noticeably improved energy, modest fat loss enhancement (30% above baseline).

Low-dose cycles often extend to 12-14 weeks without concern: lower total accumulation and slower receptor desensitization allow longer cycles. This approach suits older users (50+) or those with sensitive metabolisms.

Standard Dose (Most Users)

15-20mg weekly (5mg three times weekly or 10mg twice weekly) is optimal for most users seeking metabolic transformation. Produces noticeable improvements weeks 3-4: energy increases, glucose control improves 15-25%, fat loss rate increases 30-50%, workout recovery accelerates. This dose creates measurable body composition change over 12 weeks.

At this dose, 8-10 week breaks between cycles remain important for receptor resensitization. Many users cycle indefinitely (2-3 cycles yearly) at this dose with excellent sustained benefits and no adaptation plateau if breaks are respected.

High-Dose Protocol (Advanced)

25-30mg weekly (10mg three times weekly) produces slightly better results than standard dose: perhaps 10-15% improvement over standard dose. The diminishing return is real—going from 15mg to 25mg weekly produces only 10-15% better results despite 66% higher dose. High dose isn't necessary for most users.

High-dose protocols require shorter cycles: 8 weeks rather than 12 to prevent excessive adaptation. Breaks should remain 8-10 weeks. This aggressive protocol suits competitive users or those in time-limited metabolic optimization windows (preparation for major life events).

Injection Frequency Effects

Twice weekly (10mg per week split as 5mg twice) vs three times weekly (15mg per week split as 5mg three times): minimal difference in results. Twice weekly is simpler and produces ~90% of three-times-weekly results. This convenience makes twice-weekly standard. Professional/competitive users often choose three-times-weekly for marginal additional consistency and slightly faster results.

Daily dosing provides no advantage over weekly distribution: MOTS-c's biological half-life isn't definitively established in humans, but weekly distribution vs daily makes minimal difference. Stick with 2-3x weekly injection for simplicity.

Reconstitution and Storage Dosing

Typical vial: 5mg lyophilized powder. Reconstitute with 2ml bacteriostatic saline yielding 2.5mg/ml concentration. Inject 0.2ml (0.5mg) for micro-doses, 0.4ml (1mg), 0.8ml (2mg), 2ml (5mg), etc. Insulin syrinles allow precise small volumes. Reconstituted solution remains stable 2-4 weeks refrigerated.

Some prefer pre-made solutions: higher cost but eliminates reconstitution error risk. Most advanced users reconstitute from powder for cost efficiency: $100-150 per 5mg vial vs $200-300 pre-made.

Adjusting Dose Based on Response

Slow responders (minimal glucose improvement after 4 weeks): increase dose from 10mg to 15mg weekly. Fast responders (dramatic glucose improvement in 2 weeks): maintain dose—increasing provides diminishing return and wastes money. Individual variation is substantial: metabolism, age, baseline insulin resistance all influence optimal dose.

If fatigue emerges week 4-6 at high dose, reduce to standard dose. Excessive metabolic drive can cause mild fatigue in some users. This usually resolves with dose reduction or improved sleep/recovery.

Dose Timing for Specific Goals

Fat loss focus: standard 15mg weekly is optimal. Higher doses don't improve fat loss proportionally. Glucose control focus: even 10mg weekly often suffices for impressive glucose improvements. Longevity/anti-aging focus: 10-15mg weekly maintains mitochondrial function and prevents age-related decline without aggressive dosing.
