Pinealon effects

  • Suppresses reactive oxygen species (ROS) accumulation in neuronal cells, reducing oxidative stress-driven cell death
  • Preserves dendritic spine morphology in models of Alzheimer's and Huntington's disease, protecting synaptic integrity
  • Modulates gene expression via direct nuclear membrane penetration, regulating genes involved in neuronal survival (SOD2, GPX1, CASP3, APOE)
  • Supports serotonin biosynthesis by promoting 5-tryptophan hydroxylase expression, with potential mood-regulatory effects
  • Reduces apoptotic signaling in neurons by downregulating pro-apoptotic proteins including caspase-3
  • Reported improvement in memory, cognitive performance, and reduced headache duration in patients with traumatic brain injury sequelae

SS-31 (Elamipretide) effects

  • Stabilizes cardiolipin at the mitochondrial inner membrane
  • Restores electron transport chain efficiency and ATP production
  • Reduces mitochondrial ROS production at the source
  • Protects against ischemia-reperfusion injury in heart and kidney
  • Improves age-related mitochondrial dysfunction

Pinealon side effects

  • Injection site reactions: mild redness, itching, or transient swelling at subcutaneous injection site
  • Headache or mild dizziness, particularly early in a dosing cycle
  • Vivid dreams or mild sleep disturbance if administered late in the day (likely related to CNS activity)
  • Gastrointestinal discomfort (more commonly reported with oral capsule form)
  • Rare: transient mild anxiety or fatigue; allergic hypersensitivity reactions are possible but not well-documented in the literature

SS-31 (Elamipretide) side effects

  • Injection site reactions (pain, redness)
  • Mild headache
  • Transient flushing
  • Occasional dizziness

Pinealon dosing ranges

Cognitive support and neuroprotection (subcutaneous)

100-500 mcg · Once daily · 10-20 days per cycle, repeated 2-4 times per year

Traumatic brain injury sequelae / cerebral asthenia (oral, clinical study protocol)

0.2 mg (200 mcg) twice daily · Twice daily · 20-30 days

General anti-aging and brain longevity (oral supplement)

10-20 mg per day (1-2 capsules of 10 mg each) · Once or twice daily, 30 minutes before meals · 1 month on, then reassess

SS-31 (Elamipretide) dosing ranges

Mitochondrial support and longevity

5-50 mg · Once daily (SubQ) · 4-12 weeks

Pinealon vs SS-31 (Elamipretide) — common questions

What is the difference between Pinealon and SS-31 (Elamipretide)?

Pinealon: Neuroprotective tripeptide bioregulator that penetrates the nuclear membrane to directly regulate gene expression in brain tissue. Typical dose 100-500 mcg. SS-31 (Elamipretide): Mitochondria-targeted tetrapeptide that restores bioenergetics by stabilizing cardiolipin. Typical dose 5000-50000 mcg. Both fall under the Cognitive and Longevity categories.

Can you stack Pinealon and SS-31 (Elamipretide)?

Stacking Pinealon with SS-31 (Elamipretide) is a protocol-design question best raised with a clinician — it depends on your goal, current bloodwork, and whether both peptides target overlapping mechanisms. Both peptides should be tracked independently with separate injection sites and timing. PinnyPeptide supports multi-peptide stacks with automatic injection site rotation.

Which is dosed more frequently, Pinealon or SS-31 (Elamipretide)?

Pinealon is typically dosed: Once daily for Cognitive support and neuroprotection (subcutaneous); Twice daily for Traumatic brain injury sequelae / cerebral asthenia (oral, clinical study protocol); Once or twice daily, 30 minutes before meals for General anti-aging and brain longevity (oral supplement). SS-31 (Elamipretide) is typically dosed: Once daily (SubQ) for Mitochondrial support and longevity.

Are Pinealon and SS-31 (Elamipretide) FDA approved?

Pinealon: Not FDA approved. No IND or NDA has been submitted to the FDA. Classified as a research chemical in the United States. SS-31 (Elamipretide): Not FDA approved. FDA declined approval for Barth syndrome in 2023, requesting additional efficacy data. Multiple clinical trials ongoing for other mitochondrial indications.
