Energy & Vitality
Persistent low energy is usually a symptom, not a diagnosis. Sleep, thyroid, B-vitamin deficiency, anemia, depression, and sleep apnea are the common upstream causes — peptides are not the diagnostic. If you haven't worked through those with your doctor yet, start there.
This protocol assumes you've ruled out the obvious causes and your labs are clean. If you still feel persistently low-energy after that workup, this is the peptide-specific path most people work through. Each phase builds on the last with decision criteria so you know when to advance, when to pivot, and when to stop.
It's not the only path. Your starting point depends on what you've already tried, your specific bottleneck, and your clinician's input.
Phases
Phase 1 — Establish baseline
weeks 1-4Cofactor restoration is the cheapest, lowest-risk intervention with the clearest signal. If B-vitamin deficiency was the bottleneck, you'll feel it within 2-3 weeks. If it wasn't, you've ruled out a confounder before adding anything fancier.
- B12 (Methylcobalamin)1 mg · weekly · morning
Bioactive B12 form that bypasses methylation bottlenecks. Weekly SubQ at 1mg is the standard deficiency-correction dose.
What “working” looks like
Noticeable afternoon-energy improvement within 2-3 weeks. Less reliance on caffeine. Sustained morning energy after waking.
Decision criteria
If working by week 4: maintain through Phase 2. If not working by week 4: deficiency wasn't the bottleneck — move to Phase 2.
Labs to pull
- Serum B12
- Methylmalonic acid (MMA) — more sensitive than serum B12 alone
- Homocysteine
- Ferritin
- TSH + free T3 — rule out thyroid
- Complete metabolic panel + lipid panel
Phase 2 — Mitochondrial layer
weeks 4-12Add SS-31. Mitochondrial-targeted antioxidant that stabilizes inner-membrane cardiolipin. This is the most common bottleneck for "tired all the time" presentations after deficiency is ruled out. Strongest evidence is in cardiomyopathy populations; off-label use in healthy adults is Tier 3.
- SS-31 (Elamipretide)5 mg · daily · morning
Mitochondrial-targeted antioxidant. 5mg SubQ daily is the studied range; do not escalate dose if not working.
- B12 (Methylcobalamin)1 mg · weekly · morning
Maintain Phase 1 cofactor support throughout — energy improvements compound when the substrate layer stays stable.
What “working” looks like
Morning energy ≥30 minutes sooner after waking. Afternoon dip softens by 4-6 weeks. Exercise tolerance improves — easier to start workouts, faster recovery.
Decision criteria
If working by week 8: continue and consider Phase 3. If not working by week 6: do not escalate dose. Reassess sleep, thyroid, mood. Consider workup for chronic inflammation (hs-CRP, ESR).
Labs to pull
- Repeat baseline panel from Phase 1 if energy hasn't moved
- hs-CRP — chronic low-grade inflammation
- ESR — adjunct inflammation marker
Phase 3 — Add or transition
weeks 12+Layer in MOTS-c and NAD+ support. MOTS-c activates AMPK and improves mitochondrial bioenergetics through a different mechanism than SS-31. NAD+ provides the redox substrate both peptides depend on. Combining addresses different points on the same axis. All Tier 3 in healthy adults.
- SS-31 (Elamipretide)5 mg · daily · morning
Continue Phase 2 antioxidant support — discontinuing reverses the cardiolipin-stabilization gains.
- MOTS-c5 mg · MWF · morning
AMPK activator. 5mg SubQ on Mon/Wed/Fri layers cleanly onto SS-31 without dose escalation on either.
- Nicotinamide Riboside (NR)300 mg · daily · morning
Oral NAD+ precursor. 300mg daily is the studied range that reliably raises blood NAD+ in humans. NR is interchangeable with NMN at the substrate level.
- B12 (Methylcobalamin)1 mg · weekly · morning
Maintain the cofactor layer — full stack only works with the substrate baseline intact.
What “working” looks like
Sustained morning energy, sharper cognition, faster workout recovery, more consistent day-to-day. This is the maintenance state.
Decision criteria
If working: continue indefinitely with periodic reassessment (every 6 months — labs + symptom review). If not adding meaningful benefit over Phase 2: drop back to Phase 2 (cheaper, simpler). If new symptoms emerge: pause everything, work with clinician on differential.
Cautions
- Cardiac history: SS-31's strongest evidence is in cardiomyopathy patients. If you have a cardiac history, discuss with your cardiologist before starting Phase 2.
- Sleep is upstream. If you are sleeping less than 6 hours per night consistently, no peptide compensates for that. Fix sleep first.
- Persistent low energy can be the downstream symptom of thyroid disease, anemia, depression, sleep apnea, autoimmune conditions, or chronic infection. Peptides are not the diagnostic — the workup is. If your labs were not pulled in the last 12 months, do that before starting Phase 1.
- NAD+ infusions can transiently raise blood pressure. If you have uncontrolled hypertension, stay on oral NR rather than IV NAD+, and do not start until your BP is controlled.
- Methylation: if you carry MTHFR variants and are on SSRIs or other methyl-sensitive medications, discuss B12-methylcobalamin with your prescribing clinician before starting — over-methylation symptoms are real and can worsen mood.
Discuss with your clinician
- Order a lab panel before starting Phase 1: B12, MMA, homocysteine, ferritin, TSH, free T3, complete metabolic panel, lipid panel. Your PCP can order all of these.
- If you are on SSRIs or other psychiatric medications, ask about a methylation panel before starting B12-methylcobalamin.
- If you have any cardiac history, get cardiology sign-off before starting SS-31 in Phase 2.
- If you have sleep complaints (snoring, daytime sleepiness, partner reports apnea), ask for a sleep study before assuming the bottleneck is mitochondrial.
- Repeat your baseline lab panel every 6-12 months while on the full stack — you are looking for changes in inflammatory markers and metabolic panel, not just absolute values.
Evidence summary
Tier 3 protocol overall. Phase 1 (B12-methylcobalamin for deficiency state) is Tier 1; Phase 2 (SS-31) is Tier 2 in cardiomyopathy populations and Tier 3 for off-label energy use in healthy adults; Phase 3 (MOTS-c, NAD+/NR) is Tier 3 in healthy adults. The protocol-as-a-whole rating reflects the weakest link in the stack. The mechanistic case is coherent across phases; human-outcome evidence for stacked combinations is preclinical-to-early-clinical.

- Recovery from Injury
Cofactor and mitochondrial support in Phase 1 + 2 of Energy overlap cleanly with the tissue-repair phases in Recovery from Injury. People recovering from injury often present with low energy as a secondary symptom — the two protocols stack without conflict.
