MOTS-c reconstitution chart: units to draw by vial size and BAC water
Find the row for the mg on your vial and the water you added. Amounts are from the range on our MOTS-c page, 5 to 10 mg. Units are on a U-100 insulin syringe, where 100 units is 1 mL.
| Vial | BAC water | Strength | Units to draw for | ||
|---|---|---|---|---|---|
| 5 mg | 7.5 mg | 10 mg | |||
| 5 mg | 1 mL | 5 mg/mL | 100 | more than the vial | more than the vial |
| 2 mL | 2.5 mg/mL | 200* | more than the vial | more than the vial | |
| 3 mL | 1.67 mg/mL | 300* | more than the vial | more than the vial | |
| 10 mg | 1 mL | 10 mg/mL | 50 | 75 | 100 |
| 2 mL | 5 mg/mL | 100 | 150* | 200* | |
| 3 mL | 3.33 mg/mL | 150* | 225* | 300* | |
* Over 100 units: more than a 1 mL syringe holds in one draw. † Under 2 units: hard to measure; more water makes the draw bigger. Arithmetic from the numbers in each row. Pepdex does not pick a dose for you.
What to know about MOTS-c before you mix it
MOTS-c is a mitochondrial-derived peptide studied for metabolic flexibility, insulin sensitivity and exercise response, not a growth-hormone or healing peptide.
- How it is supplied
- There is no approved MOTS-c product. It comes as freeze-dried powder and is mixed by the user.
- Common vial sizes
- 5 mg, 10 mg. Work from the mg printed on your own vial.
- Half-life
- Listed as about 2 hours. FDA's 2026 review found no human pharmacokinetic data, so treat that figure as rough.
- Usual schedule on our page
- 3x weekly.
- FDA status
- Not FDA approved.
- Evidence in one line
- FDA's 2026 review found no clinical studies administering MOTS-c, and no human safety or pharmacokinetic data. Source: FDA bulk drug substances review, MOTS-c, 2026.
What people track with MOTS-c
- The three shot days each week
- Training sessions and energy on shot days
- Fasting glucose, if you already test it
The common MOTS-c mix-up
Large draws. MOTS-c amounts are in whole mg, so 5 mg from a 10 mg vial mixed with 2 mL is 100 units, a full 1 mL syringe. Mixed with 1 mL, the same 5 mg is 50 units.

How long a MOTS-c vial lasts
A 10 mg vial at 5 mg a shot holds 2 shots. Taken 3 times a week, that is about 5 days. Shots per vial for each size:
| Vial | At 5 mg | At 7.5 mg | At 10 mg |
|---|---|---|---|
| 5 mg | 1 shot | under 1 | under 1 |
| 10 mg | 2 shots | 1 shot | 1 shot |
MOTS-c reconstitution questions
- How much BAC water (reconstitution solution) do I add to a 10 mg MOTS-c vial?
- Any amount works for the math; it only changes the strength. 10 mg in 1 mL is 10 mg/mL, in 2 mL 5 mg/mL, and in 3 mL 3.33 mg/mL. More water gives a bigger draw that is easier to read. If your product came with mixing directions, those set the volume.
- How many units is 5 mg of MOTS-c?
- It depends on how much water is in the vial. From a 10 mg vial mixed with 2 mL, 5 mg is 100 units (1 mL). With 1 mL it is 50 units; with 3 mL, 150 units.
- How many 5 mg doses are in a 10 mg MOTS-c vial?
- 2. Taken 3 times a week, that lasts about 5 days. The water you add does not change the count, only the size of each draw.
- Is MOTS-c a growth-hormone peptide?
- No. MOTS-c is a mitochondrial-derived peptide studied for metabolism and exercise response, not GH release like ipamorelin or CJC-1295. It is a different class, and its amounts are written in whole mg rather than mcg.
Educational reference. Pepdex does not sell peptides or recommend vendors. The calculator and charts convert amounts into syringe units; whether an amount is right for you is a question for a qualified provider.
