MOTS-c
A peptide encoded directly in your mitochondrial DNA — the power plants inside every cell. MOTS-c regulates how your cells produce and use energy, improving metabolic efficiency, supporting fat oxidation, and driving the kind of cellular renewal that slows biological aging from the inside out.
Two protocol options are available — weekly injections for active metabolic support, or once-monthly for long-term longevity maintenance. Your Bespoke Biology provider will confirm the right protocol and dosing for your goals.
How MOTS-c Works
Most peptides work by signaling through hormone receptors or growth pathways. MOTS-c is different — it's encoded directly in mitochondrial DNA, which makes it one of the few peptides that originates inside the cell rather than outside it. This gives it a uniquely direct relationship with cellular energy production.
Mitochondria are the structures inside your cells that convert food and oxygen into ATP — the molecule that powers virtually every biological process. As we age, mitochondrial function declines: cells become less efficient at producing energy, more prone to accumulating cellular debris, and slower to respond to metabolic stress. MOTS-c directly activates the pathways that regulate mitochondrial efficiency, helping cells produce more energy from less fuel and clear out dysfunction that would otherwise accumulate.
The downstream effects are broad: better metabolic efficiency, improved fat burning, greater physical endurance, and reduced markers of cellular aging. Unlike stimulants that temporarily boost energy by taxing the system, MOTS-c improves how efficiently the underlying machinery operates.
Why two protocol options? The weekly protocol delivers consistent mitochondrial activation — useful for clients focused on body composition, exercise performance, or active metabolic improvement. The monthly protocol is a lower-frequency maintenance approach suited to long-term longevity support, where the goal is cellular health over time rather than active weekly metabolic output. Your provider will recommend the right cadence based on your goals.
What MOTS-c Does
Effects build progressively on the weekly protocol — most clients notice improved energy and endurance within 3–4 weeks. The monthly protocol produces slower, more cumulative benefits that compound across quarters and years of consistent use.
MOTS-c activates AMPK — the master regulator of cellular energy balance — which signals cells to increase mitochondrial efficiency and output. The result is more available ATP without stimulant side effects: steadier energy, less afternoon fatigue, and better physical and cognitive stamina throughout the day.
By improving how efficiently mitochondria process fatty acids, MOTS-c shifts the body toward using stored fat as a preferred fuel source. This is particularly pronounced during exercise and periods of caloric deficit. Over weeks of weekly dosing, clients typically notice improved body composition even without changes to diet or training intensity.
MOTS-c has demonstrated meaningful improvements in aerobic capacity and muscular endurance in research settings. Athletes and active clients on the weekly protocol typically notice they can sustain effort longer before fatigue sets in, recover between sessions more quickly, and maintain output later in workouts than before.
MOTS-c improves insulin sensitivity — the body's ability to use glucose efficiently rather than storing it as fat or leaving it circulating in the bloodstream. This makes it particularly useful for clients managing blood sugar, metabolic syndrome, or the insulin resistance that commonly accompanies aging and excess body fat.
Mitochondrial dysfunction is one of the most important drivers of biological aging — as mitochondria become less efficient, cells accumulate damage, inflammation rises, and tissue function declines. MOTS-c directly supports mitochondrial health and stress resilience, slowing this process at the cellular level. This is the primary rationale for the monthly maintenance protocol.
By improving mitochondrial function in muscle cells, MOTS-c helps maintain muscle mass and strength as we age — a process that becomes increasingly important after 40, when age-related muscle loss accelerates. It also reduces the metabolic cost of muscle maintenance, making it easier to hold onto lean tissue during caloric restriction or periods of reduced training.

Side Effects to Watch For
- /Redness or mild irritation at the injection site — rotate every injection to prevent buildup
- /Mild fatigue the day after injection — temporary, reflects metabolic adjustment
- /Rare: mild headache, self-resolving within 24–48 hours
