Remember: Research use only. This is not medical advice. These are research compounds not approved for human consumption. This is educational content only.
Dihexa
Dihexa is arguably one of the most potent cognitive enhancers available in the research space. It’s an oligopeptide derivative that acts as a hepatocyte growth factor (HGF) mimetic, promoting the formation of new synaptic connections in the brain. Research suggests it’s up to 7 times more potent than BDNF (brain-derived neurotrophic factor) at promoting synaptic growth. The mechanism involves activating c-Met receptors, which triggers signaling pathways for neuronal growth and survival. What makes Dihexa particularly interesting is its ability to potentially reverse cognitive decline and enhance learning capacity even in healthy subjects.
Mechanism of Action:
Activates c-Met receptors on neurons, triggering growth signaling cascades
Promotes synaptogenesis - literally creates new connections between brain cells
Increases BDNF-like activity but through a different pathway (7x more potent)
Enhances neuroplasticity by supporting structural changes in neural networks
Upregulates neurotrophic factors that support neuron survival and growth
Crosses blood-brain barrier efficiently despite being a peptide
Benefits:
Enhanced learning capacity and memory consolidation
Improved cognitive flexibility and mental adaptability
Promotes formation of new synaptic connections
Potential neuroprotective effects against cognitive decline
Increased neuroplasticity and brain resilience
Research Dosage: 0.5-5mg daily, typically administered orally or subcutaneously
Tesofensine
Tesofensine is a triple monoamine reuptake inhibitor that was originally developed as a treatment for Alzheimer’s and Parkinson’s diseases. It inhibits the reuptake of dopamine, norepinephrine, and serotonin simultaneously, creating a powerful effect on motivation, focus, and appetite suppression. While it became famous for its weight loss properties (showing up to 10% body weight reduction in studies), its cognitive benefits are equally impressive. The compound enhances executive function, working memory, and mental energy through its broad-spectrum monoamine activity.
Mechanism of Action:
Blocks dopamine reuptake - keeps motivation neurotransmitter active longer (prevents 60% of reuptake)
Blocks norepinephrine reuptake - maintains alertness and focus signals (prevents 60% of reuptake)
Blocks serotonin reuptake - stabilizes mood and reduces appetite (prevents 30% of reuptake)
Does NOT release stored neurotransmitters - works by preventing cleanup, not dumping reserves
Affects hypothalamic appetite centers leading to reduced food intake
Increases metabolic rate through enhanced catecholamine signaling
Benefits:
Significantly enhanced focus and concentration
Improved motivation and drive
Strong appetite suppression for body composition goals
Increased mental energy and reduced fatigue
Enhanced mood and emotional stability
Research Dosage: 0.25-0.5mg daily, taken in the morning
Noopept
Noopept is a peptide-derived nootropic that’s structurally similar to the racetam family but reportedly up to 1000 times more potent than piracetam. It works by modulating AMPA and NMDA glutamate receptors while also increasing NGF (nerve growth factor) and BDNF expression. Noopept has a rapid onset of action and is known for enhancing both memory formation and recall. Users consistently report improved verbal fluency, mental clarity, and the ability to connect ideas more rapidly. It also demonstrates neuroprotective properties by reducing oxidative stress and inflammation in neural tissue.
Mechanism of Action:

Fladrafinil (CRL-40,941)
Fladrafinil is a fluorinated derivative of adrafinil and a prodrug to modafinil, meaning it converts to modafinil in the body. It promotes wakefulness and alertness by acting as a selective dopamine reuptake inhibitor with some effects on histamine and orexin systems. What makes fladrafinil unique is its potentially faster onset and possibly reduced liver strain compared to adrafinil, though it still requires hepatic metabolism. Users report sustained energy without the jitters of traditional stimulants, enhanced focus for extended periods, and improved executive function for complex tasks.
Mechanism of Action:
Converts to modafinil through hepatic metabolism (prodrug)
Selectively blocks dopamine reuptake in specific brain regions
Increases histamine release in the hypothalamus for wakefulness
Activates orexin/hypocretin neurons that regulate arousal

It acts as a GABA-B receptor agonist while also providing some dopaminergic activity, creating a unique combination of anxiolytic and mood-enhancing effects. Phenibut is particularly valued for its ability to reduce social anxiety and promote relaxation without significant sedation at proper doses. However, it requires careful use due to tolerance development and potential dependence with daily use. Most researchers cycle phenibut 2-3 times per week maximum.

9-Me-BC is a novel nootropic compound that acts as a dopamine-enhancing agent through multiple mechanisms. It inhibits monoamine oxidase A and B (MAO-A/B), increases tyrosine hydroxylase activity, and promotes the growth of dopaminergic neurons. This makes it particularly interesting for individuals experiencing dopamine depletion from chronic stress, stimulant use, or age-related decline. Research in animal models shows it can increase dopamine levels by up to 400% and actually promote repair of damaged dopaminergic neurons.

D1 receptor activation in the prefrontal cortex is crucial for working memory, executive function, and cognitive flexibility. By selectively targeting this receptor subtype, CMS-121 aims to enhance these specific cognitive domains without the tolerance issues of traditional dopaminergic stimulants. Research is limited but suggests it may be particularly beneficial for tasks requiring working memory and mental flexibility.

The Bottom Line
This lineup from Modern Aminos represents some of the most interesting compounds in the cognitive enhancement space—from well-researched classics like piracetam to cutting-edge experimental compounds like J-147 and TAK-653. Understanding how these compounds actually work in your brain helps you make informed decisions about which ones might be worth researching for your specific goals.
Key considerations:
Start with one compound at a time to assess individual response
Many of these work better with consistent use over weeks rather than acute dosing
Cycling is crucial for compounds that build tolerance (phenibut, DMAA, etc.)
Stack synergistically: racetams with choline sources, stimulants with anxiolytics
Quality testing matters—COAs should be available for all compounds
Remember, these are research chemicals. The human data is limited for many of these compounds, and individual responses vary significantly. What works phenomenally for one person might do nothing for another.
My personal approach: I focus on compounds with the best safety profiles and research backing for regular use (Alpha GPC, CDP-Choline, basic racetams), saving the more experimental or potent compounds for specific situations requiring peak performance.
Stay safe, research thoroughly, and always start with lower doses to assess tolerance.
