Researching Neuroplasticity Peptides

[revealing]

So I've looked over a few peptides that help with neuroplasticity. What I've looked over was firstly semax and selank ofc, cerebrolysin, cortexin, dihexa, and adamax. I've had some problems, though - I've heard semax and selank were placebo or just did nothing to people, and dihexa can cause brain cancer (yeah, basically everything can cause cancer.) I want some actual information and reviews from people since I don't really want to go in blind with so many things that have mixed opinions. If any of you could tell me your experience/research on these peptides and others that would be awesome. Any risks, things to be cautious about, things to regulate, what the peptides do, doses, etc. would be greatly appreciated.

My peptide research is also along those lines. I have had noticeable results with PE-22-28, Pinealon, SS-31, BPC157, KPV, TA-1 and TB4. Several of these peptides are also good for other issues but below is some relevant info regarding the neuro benefits that you may find helpful.

Pinealon - a synthetic tripeptide (Glu-Asp-Arg) that crosses the blood-brain barrier to modulate neuroplasticity-related gene expression. It interacts directly with DNA sequences to upregulate genes responsible for neuroplasticity. It regulates neurotransmitters like serotonin, helping to protect the brain against oxidative stress, cognitive decline and allows the brain to better adapt, learn, and form new synaptic connections. Research shows it upregulates specific neuroprotective proteins in the cerebral cortex, improving neurological function and dendritic spine morphology. By modulating neurotransmitter release, it also supports natural circadian rhythms and enhances mental clarity, working memory, and focus

PE-22-28 - a synthetic peptide fragment derived from BDNF, one of the most important proteins in the brain for learning, memory, and emotional regulation. It acts as a selective TrkB (tropomyosin receptor kinase B) agonist, mimicking BDNF activity and enhancing downstream pathways that support brain health.

It is often referred to as a “BDNF mimetic” and offers potent neuroprotective and antidepressant-like effects without the overstimulation or side effects commonly seen with other mood-enhancing agents.

PE-22-28 exerts its effects by binding to and activating TrkB receptors, the same receptors activated by natural BDNF. This triggers a cascade of intracellular signaling pathways including:

PI3K/Akt Pathway

• Promotes cell survival
• Inhibits apoptosis (cell death)
• Supports neural growth and repair

MAPK/ERK Pathway

• Enhances synaptic plasticity
• Improves learning and memory
• Encourages long-term potentiation (LTP)

PLCγ Pathway

• Supports intracellular calcium signaling
• Modulates neurotrophic and neurogenic responses

By mimicking BDNF and stimulating TrkB, PE-22-28 improves neuroplasticity, helps the brain adapt to stress, and enhances emotional resilience—all crucial factors for addressing mood disorders and cognitive decline.

KPV - a tripeptide composed of the amino acids lysine, proline, and valine. It is derived from the C-terminal end of the alpha-melanocyte-stimulating hormone (α-MSH), a peptide produced by the pituitary gland. KPV also has potent anti-inflammatory and antimicrobial properties.

Anti-Inflammatory Effects:

Chronic Inflammatory Conditions: KPV can inhibit neuroinflammatory pathways (like NF-κB) and reduce pro-inflammatory cytokine production

Systemic Inflammation: KPV's systemic anti-inflammatory effects may benefit individuals with metabolic or neuroimmune disorders.

Potential Role in Neurological Health:

Brain Inflammation: Preliminary evidence suggests it might help reduce neuroinflammation, potentially
benefiting conditions like Alzheimer’s disease or traumatic brain injury.

SS-31 - The Szeto-Schiller peptide is a mitochondria-targeted antioxidant and membrane stabilizer that “protects and restores mitochondrial structure, promotes ATP synthesis, reduces electron leakage and cardiolipin peroxidation, and has no effect on healthy mitochondria” (Zhu, 2022). It does this by scavenging reactive oxygen species (ROS), which helps protect mitochondrial components such as proteins, lipids, and DNA from oxidative damage, thereby preserving mitochondrial function. By stabilizing the mitochondrial inner membrane, it assists with electron transport and ATP production and energy metabolism. SS-31 has anti-apoptotic properties, meaning it can inhibit programmed cell death. It helps maintain mitochondrial membrane potential and prevent the release of pro-apoptotic factors from mitochondria, thereby preserving cell viability (Pang, 2015). Additionally, SS-31 has been shown to reverse the mitochondria fragmentation (Machiraju et al., 2019). This helps with both normal mitochondria degradation as well as mitochondrial dysfunction-related conditions such as heart failure, ischemia-reperfusion injury, neurodegenerative diseases, and metabolic disorders.

Thymosin beta-4 & Thymosin alpha-1: Peptides derived from the thymus that have roles in immune modulation and anti-inflammatory processes, may improve neurological outcomes after stroke or brain damage.

BPC157 Neuro and cardio protection

Neuroprotective benefits -

• lnfluences serotonergic, dopaminergic, opioid and GABAergic systems
• Improves nerve regeneration
• Decreases neuroinflammation

Your research area conflates with my own domain -- perhaps I should share my results with you or work together.

So far, my Rat is in a learning trial, on a peptide stack (and a supplement stack as well) consisting of:

Peptide Stack

Cjc-1295 + Ipa (Great for energy)
DSIP (Deep Sleep Inducing Peptide) (Great for deeper sleep,aids learning)
Adamax (Taken in the morning)
Selank (Always must be taken at least 1 hour after Adamax, taken on nights.)

Supplement stack:

Liposal Vitamin C (Vitamin C encased in heavy fat for better absorption)
Lions Mane extract (large amounts)

So far, the research stack has reduced ADHD symptoms significantly, leading to a significant reduction of the usage of detroampthetamines for the treatment ADHD; Adamax is effective alone for this! (but for removal of brainfog, supplementation and DSIP is important)

Would love to collaborate with your research!

@revealing

How would you rank the effectiveness of each Peptide in how it aids memory retention and effective learning? What is the most effective, to the least effective.

I am currently trying to reconstitute Dihexa, and then I will go onto to a couple of ones you have mentioned in your post (They're in my own list for my research).

Just curious to the 'subjective experience' ,and how in your opinion, how each one is effective.

@EstrogenDragonLover
So far I haven't tried anything because I don't feel like wasting my money on something that probably won't work well or will just make me feel horrible. I was told to just buy and test and if it doesn't work just throw it away, which I will probably do. I'll have to try Selank + Adamax since those seem like the safest option currently, as they are intranasal and don't seem to have very crucial side effects. I'll have to try with supplements aswell but it's pretty hard for me to take every single supplement daily because I have so many to keep track of, but if they really do help then I'll consider trying those. Thank you for your research/trials info, it's much appreciated.

@EstrogenDragonLover What kind of neuro issues and symptoms are you dealing with?

[EstrogenDragonLover]

Mainly Verbal recall, but also some brain fog, bad short term memory, bad memory recall.. Overall looking for a 'learning enhancer' and a memory enhancer.

Adamax works wonders for my rat, but I think I need a few others on top... any help would be appreciated @brithus

Memory and learning results are often uniquely varied with each lab subject. A lot of different things can affect memory issues like injury, disease, nutritional deficiency and aging.

For age-related memory enhancements with no other known issues, I personally would start by checking labs on vitamin levels for vitamins D, K, B12, B6, Folate & iron/ferritin. Deficiency in these can significantly speed up age-related cognitive decline, and reduce brain fog, learning, focus, and memory abilities. Research studies show that nearly half of people with aging memory/learning problems are deficient in many of these nutrients. Another supplement that is useful but you cant really test is DHA/EPA (omega 3). Make sure you use a quality supplement brand though or you will be wasting your time and money.

If you dont have nutritional deficiencies or injury/disease related and just want to enhance learning and memory abilities, I would start with prptides that increase BDNF and synaptic plasticity. The ones I have personally found most helpful are Pinealon, Semax (or a Selank/Semax combo was better in my opinion), and NAD+. Dihexa and P21 are also good but nearly impossible to find lately.

If your issues are from aging then you may want to also look into peptides that deal with cell renewal, neuroinflammation and mitochondrial repair. I have found BPC-157, TB500, KPV, SS-31, Epitalon, FOXO4-DRI, and Ipamorelin to be most beneficial for me. Hope this helps.
