NSI-189 Review: Benefits, Dosage & Where to Buy

When compared to NSI-189, people suffering from depression and cognitive impairment typically do not get the intended impact from their medicine.

MDD, or major depressive disorder, is a serious medical condition that may result in death and impairment of function.

NSI-189 is being developed as a new medicine to help with treatment and prevention.

But what precisely is it and how does it function? Let’s have a look and see.

What exactly is NSI-189?

NSI-189 is a neurogenic chemical under development that might be used to treat MDD, traumatic brain injury, stroke, cognitive issues, mental disorders, post-traumatic stress disorder, and aging-related neurodegenerative disease.

NSI-189 is being developed by Neuralstem Inc, a biopharmaceutical business. The substance is being studied as an alternative therapeutic for individuals who have not responded to traditional treatments.

The phase I clinical trials [R] were completed by 41 participants in 2011. Following that, between 2012 and 2014, a phase IB study focused on treating individuals with MDD [R].

The phase II clinical study, however, was not as effective as the phase I. In MDD [R], it did not fulfill the standards for the main efficacy objective.

NSI189 is now being studied for a variety of illnesses, including enhanced brain health, diabetic neuropathy, stroke, neurodegenerative disease, post-traumatic stress disorder, and Angelman syndrome. Traumatic brain damage is treated using it.

The FDA has given NSI-189 Orphan Drug Designation as a therapy for Angelman syndrome, a rare condition.

The research included patient recruiting as well as NSI imaging.

NSI-189, like other antidepressants, increases hippocampus volume. What makes it unique is its capacity to screen for substances that cause the rise in rodents.

Because a human clinical study is still needed, its capacity to boost hippocampus volume makes it a better depression medicine.

Action Mechanisms

NSI-189 may alter the areas of the brain that control learning, memory, and emotion by promoting neurogenesis in hippocampus-derived neural stem cells. This occurs as a result of many mechanisms.


The medication is a benzylpiperazine-aminopyridine that has the potential to cross the blood-brain barrier.

The hippocampal slices, especially the left side of the human brain, induce neurogenesis.

It may raise Ki67 and MAP2 in specific instances, such as after a stroke. It also helps to boost BDNF, GDNF, and VEGF levels.

On the Skp, Cullin, and F-box containing complex, there are other indicated activities.

Other Potential Mechanisms

NSI-189 exhibits a few additional pathways that might support its effectiveness as a better depression therapy.

NSI 189 enhances hippocampus growth by 20% in the brain and improves glucocorticoid resistance through modulating aldosterone receptors.

Other potential methods include TRPV1 antagonists and binding affinity norepinephrine-dopamine reuptake inhibitors.

Benefits & Effects

To verify the effectiveness of this nootropic and its potential to cure mental problems, a suitable human clinical study must be done.

But, since there isn’t any, this NSI 189 review sets out the advantages of using the product right now.

Human Research

  • Depression has improved. Taking 40 mg to 80 mg of NSI 189 per day for 28 days demonstrated substantial reductions in depression symptoms in multiple participants in a placebo-controlled research.
  • Cognition has improved. Participants in the phase I study experienced self-reported improvements in cognition. This encompasses not just memory but also learning and concentration abilities.

Animal Research

The supplement demonstrated more of its beneficial advantages for people.

  • Stroke with ischaemia. After an artificial stroke, rats in a research showed better brain and motor impairments. NSI-189 prevents cells from dying due to a lack of oxygen. It lasted for 24 weeks.
  • Diabetic neuropathy is a condition caused by diabetes. Neuropathy is a kind of nerve injury that may occur in people with diabetes. NSI-189 assists in the formation of neurons and prevents additional damage to the brain and limbs to help heal the nerve.
  • The Angelman condition. Because of Angelman syndrome, the neurological system is the most afflicted component of the body. It’s a mental and motor skill disease caused by a genetic mutation. NSI 189 restores function via activating the TrkB and Akt pathways.

NSI-189 Reviews & Experiences Shared on Reddit

Despite the absence of a proper human clinical study, the phosphate compound was accessible for human ingestion on the market.

Here’s what people say about their experiences with NSI 189.

Elasticoder claims that:

“I’ve been using it for a month in conjunction with a consistent exercising routine and vitamins. I must say that the results are amazing. I mix 40 mg in coffee or orange juice every morning. You will feel the effects within 15 minutes. At first, you will feel stimulated and motivated. The feeling is similar to Adderall but less intense and healthier…The best part about NSI-189 is that there is no withdrawal if you stop taking it at any point. Last but not least, this compound is very hard to find. I managed to find a legit vendor with authentic signed lab reports. You can check out their site ->https://science.bio/.”

falre1028us claims that:

“NSI-189 has proven to be really valuable to me. I take 50 mg of freebase once a day in the morning. A soft wave of tranquility, increased long-term memory, and noticeably improved eyesight are the immediate results for me.”

ThechanceW claims:

“So, around a month ago, I began taking NSI-189, a freebase supplement purchased from science.bio… I took 40mg sublingually the first day, however it had no impact… I repeated the process on the second and third days with no noticeable results. I took 40mg with water on the fourth day and experienced a minor mood enhancement. I’ve been taking between 80 and 110mg orally in the morning for the last five days, sometimes on an empty stomach, sometimes not, and I feel like I’ve been resurrected.”

What’s the Difference Between NSI-189 Freebase and Phosphate Powder?

When both freebase and phosphate are accessible, people are often confused about which one to choose.

Both types improve depressed symptoms while also demonstrating improved cognitive performance.

To offer additional clarity, here’s what you should know about their differences.


Neuralstem Inc has been using phosphate in its clinical studies. It’s best taken orally and costs around 15% to 20% more than the other form, but it’s a lot more stable and has superior bioavailability.


For sublingual ROA, the freebase version is utilized. The nitrogen atom is linked to two carbon atoms and one hydrogen atom in the secondary amine. Bioavailability is weak.

If you’re thinking about buying NSI 189, keep the above considerations in mind to figure out if you want the free base or the phosphate.

Where to Buy Phosphate, NSI-189 Powder?

Due to its rarity, finding NSI 189 for sale might be difficult. Even if there is availability in the market, there are still important things to verify to guarantee that your selected seller is trustworthy and that the product you are purchasing is genuine.

Some vitamins and chemicals are overpriced, while others are underpriced. To prevent difficulties with NSI-189, purchase from reputable vendors and make sure to verify the following:

Organoleptic verification is a time-consuming way of determining the identity of chemicals.

If the chemical’s real look and physical qualities match the web reports, this technique is used.

In organoleptic verification, appearance, taste, and smell are often checked. The chemical is crystalline in appearance, has a mild odor, and a bitter taste.

In comparison to other compounds, NSI-189 is not very thick. A 0.15cc scoop of the supplement contains 50 milligrams.

Patients with cognitive impairments and depression symptoms are often treated with this dose. The 40-120 mg NSI 189 dose may be used in a clinical research.


NSI-189 is being developed as a therapy for major depressive disorder.

Despite the absence of a human research, it was determined to be a viable antidepressant medicine and the FDA gave it Orphan Drug Designation.

It also causes favorable brain reactions, which may help to enhance cognition and cure traumatic brain damage or aging.

The phase I clinical study raised optimism in the medical community that a substantial new antidepressant would be discovered.

However, other critical features of NSI-189’s effectiveness as a novel method for treating depression and cognitive illness must be addressed and evaluated.
