Adamax

Synthetic nootropic peptide with N-terminal acetylation and C-terminal adamantane modification for superior stability and blood-brain barrier penetration, researched for cognitive enhancement, neuroprotection, and neuroplasticity.

COA Verified

Purity: ≥98% (HPLC verified)

Cerebrolysin

Standardized neuropeptide preparation containing bioactive peptides and amino acids exhibiting neurotrophic and neuroprotective properties for stroke recovery, traumatic brain injury, and cognitive enhancement. Used clinically in 50+ countries.

COA Verified

Purity: ≥98% (HPLC verified)

Cortagen

Cortagen is a Khavinson bioregulator tetrapeptide (AEDP) with primary effects on the brain and central nervous system. Developed at Russia's St. Petersburg Institute of Bioregulation and Gerontology, it regulates inflammatory responses in the nervous system, restores balance between pro- and anti-oxidative processes, and stimulates interleukin-2 expression. Research shows potential benefits for ischemic brain injury recovery, nerve regeneration, and reducing autoimmune reactions affecting the CNS.

COA Verified

Purity: ≥98% (HPLC verified)

N-Acetyl Selank Amidate

NA-Selank Amidate is an enhanced version of Selank, the anxiolytic nootropic peptide developed at Russia's Institute of Molecular Genetics. The N-acetyl group improves blood-brain barrier penetration and creates more stable metabolites, while the C-terminal amidation further enhances metabolic stability and receptor binding. Unlike benzodiazepines, it provides anxiety relief without sedation, dependency, or cognitive impairment.

COA Verified

Purity: ≥98% (HPLC verified)

N-Acetyl Semax Amidate

Enhanced and stabilized version of Russian nootropic Semax with superior stability, extended half-life, and enhanced bioavailability through acetylation and amidation modifications.

COA Verified

Purity: ≥98% (HPLC verified)

P21 with Adamantane

P21 with Adamantane is an adamantane-modified form of the P21 peptide. The modification is designed for research into altered physicochemical properties and CNS-related delivery characteristics.

COA Verified

Purity: ≥98% (HPLC verified)

P21 (without Adamantane)

P21 is a nootropic peptide derived from ciliary neurotrophic factor (CNTF) that enhances neurogenesis and cognitive function. This product is the unmodified form of P21 and does not contain an adamantane moiety.

COA Verified

Purity: ≥98% (HPLC verified)

PE 22-28

Synthetic heptapeptide derived from Spadin positions 22-28, functioning as potent TREK-1 antagonist with enhanced selectivity and duration versus parent compound. Primary research focus on rapid antidepressant effects.

COA Verified

Purity: ≥98% (HPLC verified)

Pinealon

Developed in Russia, Pinealon demonstrates unique DNA-interaction for neuroprotection and cognitive enhancement. Benefits traumatic brain injury recovery and age-related cognitive decline with excellent safety profile.

COA Verified

Purity: ≥98% (HPLC verified)

Selank

Selank is a synthetic heptapeptide analog of the naturally occurring immune peptide tuftsin, developed by the Russian Academy of Sciences. It provides anxiolytic effects comparable to benzodiazepines but without sedation, amnesia, tolerance, or withdrawal.

COA Verified

Purity: ≥98% (HPLC verified)

Semax 10mg + Selank 10mg Blend

Research blend combining Semax and Selank peptides. RaysunPeptide manufactures and supplies Semax 10mg + Selank 10mg Blend for qualified research, laboratory, and B2B applications.

COA Verified

Purity: ≥98% (HPLC verified)

Semax

Semax is a synthetic heptapeptide derived from adrenocorticotropic hormone (ACTH) fragment 4-10, originally developed in Russia for stroke recovery. It achieves enhanced CNS penetration through direct transport via olfactory epithelium and trigeminal nerves, bypassing the blood-brain barrier.

COA Verified

Purity: ≥98% (HPLC verified)
