How much bacteriostatic water with MOTS-c?
Most research-handling protocols use 1 mL of bacteriostatic water per 10 mg MOTS-c vial, yielding a 10 mg/mL working concentration. MOTS-c protocols in the published research use larger per-draw amounts (5-10 mg subcutaneously, 2-3 times per week), which 10 mg/mL accommodates at 50-100 syringe units.
What the research literature says
MOTS-c dosing across the published research literature uses larger per-draw amounts than most peptide-research compounds because the compound’s mechanism (AMPK-axis activation across multiple tissues) operates at higher effective concentrations than receptor-targeted compounds. Standard preclinical protocols span 5-10 mg subcutaneously on a 2-3 times weekly schedule across 4-8 week research programs.
For a 10 mg vial reconstituted with 1 mL of bacteriostatic water (10 mg/mL): a 5 mg dose draws 50 units on an insulin syringe; the full 10 mg fills the barrel of a 1 mL syringe. With 2 mL fill (5 mg/mL), 5 mg = 100 units (full barrel) and larger doses require multiple draws or larger-barrel syringes. The 1 mL fill is the typical pick because it keeps the typical 5-10 mg dose tier within a single syringe draw.
The Lee characterisation work established the metabolic-homeostasis framework with AMPK activation as the primary mechanism (PMID 25738459, PMID 27216708). The Yang exercise-synergy work documented dose ranges relevant to typical research protocols (PMID 33722744).
Why this matters in research context
MOTS-c’s reconstitution-volume choice tracks the larger per-draw doses typical of the compound’s published protocols. Smaller reconstitution volumes (higher concentration) keep per-draw syringe volumes practical at the higher dose tiers; researchers running lower-dose dose-finding protocols can use larger reconstitution volumes for finer per-draw precision at the cost of larger syringe draws.
