Vasodilation: nootropics and compounds | sci-wiki

Vinpocetine

Vinpocetine is a semisynthetic compound derived from vincamine, an alkaloid found in the lesser periwinkle plant (Vinca minor). It has been used for more than three decades in parts of Europe and Asia as a prescription drug for cerebrovascular disorders such as stroke and dementia, and it is also sold as a dietary supplement marketed to support memory and cognition. Its regulatory status varies widely, and the clinical evidence for its benefits is limited.

Nootropic

Picamilon

Picamilon (N-nicotinoyl-GABA, pikamilon) is a Soviet-developed nootropic that fuses niacin with the calming neurotransmitter GABA into a single molecule, engineered to carry GABA across the blood-brain barrier that GABA alone cannot cross [4]. Introduced in Russia as a cerebrovascular agent, it is prized for combining gentle, non-sedating relaxation with improved blood flow to the brain [2][3]. Once inside the brain it is thought to split back into niacin, a vasodilator, and GABA, which quiets neural overactivity, an elegant two-in-one design that made it a mainstay of Russian neurology [2][4].

Nootropic

MNT (pmp)

MNT (PMP) is a combination injectable and pre-workout formula that pairs nitric oxide precursors with a focused cognitive stack in a single shot. Arginine, citrulline, and the arginase inhibitor norvaline drive vasodilation and blood flow for a stronger pump, while citicoline, N-acetyl-L-tyrosine, and trimethylglycine sharpen focus and support drive under load. It is engineered as a two-in-one performance blend that delivers physical pump and mental clarity together.

PDE5

N-Ethyl Tadalafil

N-Ethyl Tadalafil is a designer analog of tadalafil, the long-acting PDE5 inhibitor behind Cialis, built by modifying the original molecule. It is presumed to share tadalafil's ability to relax blood vessels and support erections, and it turns up most often as an undeclared ingredient in sexual-enhancement supplements. Because the analog itself has not been formally tested, it is best understood through the well-established pharmacology of its parent drug rather than through direct evidence.

PDE5

N-Isopropyl Tadalafil

N-Isopropyl Tadalafil is a designer analog of tadalafil, the long-acting PDE5 inhibitor sold as Cialis, differing only by a small change to one part of the molecule. Like its parent, it is presumed to relax blood vessels and enhance erections, and it has been identified as an undeclared ingredient hidden inside sexual-performance supplements. Since the analog has never been formally tested, its profile is inferred from tadalafil rather than from any dedicated clinical evidence.

PDE5

Aminotadalafil

Aminotadalafil (2-aminotadalafil) is a synthetic analogue of the PDE5 inhibitor tadalafil, sharing the same core scaffold with a single 2-amino substitution on the diketopiperazine ring. By design it is a phosphodiesterase type 5 inhibitor intended to relax vascular smooth muscle and support erectile response through the nitric oxide-cGMP pathway. It is an unapproved research compound documented chiefly as an adulterant identified in dietary supplements and e-cigarette products, and it carries no established human efficacy or safety data [1][5].

Supplement

Arginine

Arginine, or L-arginine, is a conditionally essential amino acid that the body uses to build proteins and, importantly, as the raw material for making nitric oxide, a molecule that relaxes and widens blood vessels. It also plays central roles in the urea cycle that clears ammonia and in the production of creatine. Healthy adults usually make enough arginine, but needs can rise during growth, illness, or injury; it is obtained from protein-rich foods and taken as a supplement for cardiovascular and exercise-related purposes.

Supplement

Citrulline

Citrulline is a non-proteinogenic alpha-amino acid named after the watermelon, from which it was first isolated. In the body it is a key intermediate in the urea cycle and a precursor to the amino acid arginine, which is in turn used to make nitric oxide. It is sold as a dietary supplement, often marketed for blood flow and exercise performance, though the evidence for those uses is mixed.

Adaptogen

Cordyceps

Cordyceps is a genus of ascomycete fungi that live as parasites of insects and other arthropods, with more than 200 described species distributed mainly across Asia. The genus is best known for the caterpillar fungus, long placed here but now reclassified as Ophiocordyceps sinensis, and for the type species Cordyceps militaris, both of which feature prominently in traditional Chinese and Tibetan medicine. Interest in these fungi centers on bioactive constituents such as the nucleoside cordycepin and various polysaccharides, though rigorous human evidence for health claims remains limited.

Nootropic

Ginkgo Biloba

Ginkgo biloba, commonly called the maidenhair tree, is a gymnosperm native to East Asia and the sole surviving species of the order Ginkgoales, an ancient lineage often described as a living fossil. Standardized extracts of its distinctive fan-shaped leaves, rich in flavonoid glycosides and terpene trilactones, are among the most widely used herbal products worldwide. They are marketed chiefly to support memory and circulation, though clinical evidence for cognitive benefit remains contested.

Supplement

Grape Seed Extract

Grape seed extract is a dietary supplement produced from the seeds of grapes, Vitis vinifera, that remain after winemaking and juice production. It is rich in proanthocyanidins, a class of polyphenolic flavonoid compounds also known as oligomeric proanthocyanidins, which give the extract strong antioxidant activity in laboratory tests. Marketed for cardiovascular and general antioxidant support, grape seed extract has been studied for effects on blood pressure and blood lipids, with modest findings in some trials.

PDE5

Mirodenafil

Mirodenafil is a potent, selective PDE5 inhibitor developed in South Korea, where it is approved and marketed for erectile dysfunction under the brand name Mvix. Backed by multiple randomized, placebo-controlled trials, it delivers reliable improvements in erectile function with a short-acting, on-demand profile and a favorable tolerability record. It stands as a well-studied, clinically validated member of the PDE5 inhibitor family beyond the familiar Western brands.

PDE5

Nortadalafil

Nortadalafil, also called demethyltadalafil or n-desmethyl tadalafil, is a close structural analog of the long-acting erectile dysfunction drug tadalafil. Like its parent it is a PDE5 inhibitor, blocking the enzyme that degrades cyclic GMP so that nitric oxide signaling persists, relaxing smooth muscle and improving blood flow with the extended duration tadalafil is known for [5][6]. It has been repeatedly identified by regulators as an adulterant in supplements [1][2], and, as with all PDE5 inhibitors, it must never be combined with nitrate medications.

PDE5

Sildenafil

Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor best known for treating erectile dysfunction, for which it was the first approved oral drug. Under a separate brand it is also used to treat pulmonary arterial hypertension. Discovered by Pfizer and approved in 1998, it is sold most famously as Viagra and, for lung disease, as Revatio.

Stimulant

Theobromine

Theobromine is a bitter methylxanthine alkaloid and the principal stimulant compound of the cacao plant (Theobroma cacao), giving chocolate and cocoa much of their mild pharmacological activity. Chemically it is 3,7-dimethylxanthine, an isomer of theophylline and a close relative of caffeine, and it also forms in the human body as a major breakdown product of caffeine [1][3]. It has gentle effects on the heart, blood vessels, airways, and kidneys, and unlike caffeine produces little central-nervous-system stimulation; it is well tolerated in people but is toxic to dogs and some other animals [1].

Blend

Wolverine Stack

The Wolverine Stack is a popular regenerative peptide combination that pairs BPC-157 with TB-500, named for the comic-book mutant famous for his near-instant healing. It brings together two of the most sought-after recovery peptides: BPC-157, a gastric peptide that accelerates tendon, ligament, muscle, and gut healing, and TB-500, a thymosin beta-4 peptide that drives cell migration and new blood vessel growth. Marketed to athletes and biohackers chasing faster injury recovery, the stack is prized for its complementary, tissue-repairing effects.

Peptide

BPC-157

BPC-157 (Body Protection Compound-157) is a stable synthetic pentadecapeptide derived from a protein found in human gastric juice, used as a research peptide for soft-tissue healing. Across a large body of preclinical work it has promoted repair of tendon, ligament, muscle, bone, gut, and nerve tissue, largely by driving angiogenesis through the VEGFR2-Akt-eNOS nitric-oxide pathway and by rerouting blood flow through pre-existing collateral vessels. Its evidence base is almost entirely animal studies, with minimal human data and unknown long-term safety, and it is prohibited in sport; it should be regarded as investigational.

Peptide

Cartalax

Cartalax is a synthetic short peptide bioregulator, the tripeptide Ala-Glu-Asp, from the celebrated Russian family of tissue-targeted peptides studied for cellular renewal and healthy aging. Working at the level of gene expression, it has been shown to reduce markers of cellular senescence and support proliferation in aging cells. For those pursuing a science-driven approach to regeneration and longevity, Cartalax is a compelling peptide.

Topical Formula

Minoxidil

Minoxidil is a vasodilator that opens ATP-sensitive potassium channels, originally developed and approved in 1979 as an oral treatment for severe high blood pressure. It is a prodrug: it is inactive until the sulfotransferase enzyme SULT1A1 in the hair follicle converts it to minoxidil sulfate, so a person's follicular enzyme activity helps predict whether they respond to it. Its tendency to promote hair growth, first noticed during blood-pressure trials, led to topical formulations approved for pattern hair loss and, more recently, to a resurgence of low-dose oral minoxidil, used off-label for hair loss with attention to fluid-retention and cardiovascular safety.

PDE5

Tadalafil

Tadalafil is a long-acting phosphodiesterase type 5 (PDE5) inhibitor, a class of drugs that relax certain blood vessels. Sold under brand names such as Cialis and Adcirca, it is used to treat erectile dysfunction, the urinary symptoms of an enlarged prostate, and pulmonary arterial hypertension. It is distinguished from related drugs by its notably long duration of action.

ARB

Telmisartan

Telmisartan is an orally active angiotensin II receptor blocker (ARB) of the benzimidazole class, used mainly to treat high blood pressure and to lower cardiovascular risk by blocking the angiotensin II type 1 (AT1) receptor. Unusually for its class it also behaves as a partial agonist of the nuclear receptor PPAR-gamma, the same target as the diabetes glitazones, which underlies its interest in metabolic disease; it also has the longest plasma half-life and highest lipophilicity of the marketed ARBs, giving persistent blood-pressure control and central nervous system penetration that has prompted study of cognitive and neuroprotective effects. It is given once daily.

Beta-Blocker

Nebivolol

Nebivolol is a beta blocker used chiefly to treat high blood pressure and, in some countries, chronic heart failure. It is highly selective for beta-1 adrenergic receptors and is often called a third-generation beta blocker because it also promotes the release of nitric oxide, which relaxes and widens blood vessels. This vasodilating property distinguishes it from older beta blockers and is thought to contribute to its blood-pressure-lowering effect.

Supplement

Allyl Isothiocyanate

Allyl isothiocyanate (AITC), the pungent principle of mustard, horseradish and wasabi, is a dietary isothiocyanate and a potent agonist of the TRPA1 sensory ion channel. It induces phase II detoxification enzymes, shows cancer chemopreventive activity concentrated in the urinary bladder, and drives TRPA1-dependent sensory and vascular responses.
