DNSP-11 vs Pinealon

Side-by-side comparison: effects, dosing ranges, side effects, regulatory status, and reconstitution.

Peptide A

DNSP-11

Cognitive

Eleven-amino-acid peptide derived from the GDNF prodomain — neuroprotective for dopamine neurons.

Peptide B

Pinealon

Cognitive

Neuroprotective tripeptide bioregulator that penetrates the nuclear membrane to directly regulate gene expression in brain tissue.

Typical vial

5 mg

Typical dose

Variable (research-specific) mcg

Half-life

Short; precise value uncharacterized

FDA status

Not FDA approved.

Typical vial

20 mg

Typical dose

100-500 mcg

Half-life

~1-2 hours (estimated; formal pharmacokinetic data in humans is not published — biological effects on gene expression persist beyond plasma clearance)

FDA status

Not FDA approved. No IND or NDA has been submitted to the FD…

DNSP-11 effects

  • Dopaminergic neuroprotection in Parkinson's models
  • Increased dopamine production in dopaminergic neurons
  • Improved motor function in 6-OHDA and MPTP models
  • Mechanism distinct from full-length GDNF
  • Investigational for Parkinson's and related disorders

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

DNSP-11 side effects

  • Essentially uncharacterized in humans
  • Possible local tissue effects with intracerebroventricular delivery
  • Theoretical: off-target effects on non-dopaminergic neurons
  • Injection-site reactions

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

DNSP-11 dosing ranges

Research / Parkinson's models (preclinical)

Variable per protocol · ICV or peripheral routes · Per research design

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

DNSP-11 vs Pinealon — common questions

What is the difference between DNSP-11 and Pinealon?

DNSP-11: Eleven-amino-acid peptide derived from the GDNF prodomain — neuroprotective for dopamine neurons. Typical dose Variable (research-specific) mcg. Pinealon: Neuroprotective tripeptide bioregulator that penetrates the nuclear membrane to directly regulate gene expression in brain tissue. Typical dose 100-500 mcg. Both fall under the Cognitive category.

Can you stack DNSP-11 and Pinealon?

Stacking DNSP-11 with Pinealon 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, DNSP-11 or Pinealon?

DNSP-11 is typically dosed: ICV or peripheral routes for Research / Parkinson's models (preclinical). 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).

Are DNSP-11 and Pinealon FDA approved?

DNSP-11: Not 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.
