01Mechanism of Action

Parameter
Glutathione
Pinealon
Primary target
Intracellular redox systems, glutathione peroxidase, glutathione transferase
Antioxidant defense + neuronal gene expression (proposed)Khavinson 2014
Pathway
Synthesized via glutamate-cysteine ligase (GCL) → γ-glutamylcysteine → glutathione synthetase (GS) → GSH
Modulation of antioxidant enzymes (SOD, catalase) + neurotrophic factor expressionKhavinson 2014
Downstream effect
Reduction of reactive oxygen species, conjugation of electrophiles, maintenance of cellular thiol-disulfide balance, GPX4 activation for lipid peroxide reduction
Reduced oxidative stress in neurons; improved cognitive function in age-related declineKhavinson 2014
Feedback intact?
Origin

02Dosage Protocols

Parameter
Glutathione
Pinealon
Endogenous synthesis
Hepatic synthesis ~10 g/day (basal rate)
Tissue-specific; demand-driven upregulation via Nrf2 signaling.
Exogenous oral
250–1000 mg/day
Bioavailability limited; gastric hydrolysis reduces systemic uptake.
IV supplementation
600–1200 mg (research protocols)
Used in clinical oxidative stress and hepatic detoxification studies.
Precursor strategy
N-acetylcysteine (NAC) 600–1200 mg/day
Provides cysteine for endogenous GSH synthesis; bypasses GI degradation.
Evidence basis

05Administration Protocol

Parameter
Glutathione
Pinealon
1. Oral administration
Capsule or liquid form, 250–1000 mg once daily. Take on empty stomach for improved absorption, though GI hydrolysis limits bioavailability. NAC precursor strategy often preferred.
Add 1–2 mL bacteriostatic water to 10 mg vial.
2. Intravenous
Clinical protocols: 600–1200 mg slow infusion over 30–60 minutes. Used for acute oxidative stress, hepatic detoxification support. Administered in medical settings.
SQ — abdomen preferred.
3. Inhaled formulations
Nebulized GSH (research protocols). Monitor for bronchospasm in reactive airway patients. Used experimentally for pulmonary oxidative stress.
Daily during cycle, any time.
4. Precursor supplementation
N-acetylcysteine (NAC) 600–1200 mg/day PO. Provides cysteine substrate for endogenous GSH synthesis. Bypasses gastric degradation, preferred for chronic supplementation.
Lyophilised: room temp. Reconstituted: refrigerate ≤30 days.
5. Needle
29–31G, 4–8 mm insulin syringe.

— no documented stacks
Pinealon
+ Epitalon
Moderate
View Epitalon

Pinealon (neuroprotection) + Epitalon (telomerase activation) form the canonical Khavinson "longevity stack" — both pineal-derived bioregulators with complementary axes. Pinealon supports neuronal antioxidant defense; Epitalon supports telomere maintenance. Anecdotally cycled together 1–2× per year.

Pinealon
5–10 mg SQ · daily × 10 days
Epitalon
5–10 mg SQ · daily × 10 days (overlap or alternate)
Primary benefit
Neuroprotection + telomere preservation
