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

Thymosin Alpha-1 effects

  • Enhances T-cell maturation and differentiation
  • Activates natural killer cell cytotoxicity
  • Stimulates dendritic cell function and antigen presentation
  • Modulates cytokine production (IFN-alpha, IL-2)
  • Improves vaccine response in immunocompromised patients

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

Thymosin Alpha-1 side effects

  • Mild injection site discomfort
  • Transient flu-like symptoms during initial immune activation
  • Occasional fatigue
  • Rare mild fever

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

Thymosin Alpha-1 dosing ranges

Immune modulation

1000-1600 mcg · Twice weekly (SubQ) · 6-12 months

Hepatitis treatment (clinical protocol)

1600 mcg · Twice weekly · 6-12 months

Acute immune support

1600 mcg · Daily for initial phase, then twice weekly · 2-4 weeks acute, then maintenance

Pinealon vs Thymosin Alpha-1 — common questions

What is the difference between Pinealon and Thymosin Alpha-1?

Pinealon: Neuroprotective tripeptide bioregulator that penetrates the nuclear membrane to directly regulate gene expression in brain tissue. Typical dose 100-500 mcg. Thymosin Alpha-1: Thymic peptide with broad immunomodulatory activity, approved in over 35 countries. Typical dose 1000-1600 mcg. Both fall under the Cognitive and Immune categories.

Can you stack Pinealon and Thymosin Alpha-1?

Stacking Pinealon with Thymosin Alpha-1 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 Thymosin Alpha-1?

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). Thymosin Alpha-1 is typically dosed: Twice weekly (SubQ) for Immune modulation; Twice weekly for Hepatitis treatment (clinical protocol); Daily for initial phase, then twice weekly for Acute immune support.

Are Pinealon and Thymosin Alpha-1 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. Thymosin Alpha-1: Not FDA approved. Granted orphan drug designation for hepatocellular carcinoma and hepatitis B. Multiple clinical trials conducted but no NDA submitted.
