Semax, or ACTH (4-7) Pro-Gly-Pro, is a research peptide offering various potential neuroprotective and cognitive benefits.
It is a heptapeptide made of 4 amino acids (Met-Glu-His-Phe) at the N-terminus taken from ACTH(4-7) and a Pro-Gly-Pro fragment at the C-terminus [1].
This unique chemical structure was engineered to let Semax directly cross the blood-brain barrier (BBB) and exert its therapeutic effects [2, 3].
Semax was first developed in the former Soviet Union in the late 1980s. The research peptide is believed to offer potential therapeutic benefits for individuals suffering from dementia, stroke, general cognitive decline, and other cognitive diseases [4].
The latest studies show that Semax likely works by activating dopaminergic and serotonergic brain systems, increasing levels of Brain-Derived Neurotrophic Factor (BDNF) and Nerve Growth Factor (NGF), and protecting neurons against oxidative stress [5, 6, 7, 8, 9].
In addition to its regular form, Semax is also available as an acetylated and amidated formulation, known as N-Acetyl Semax Amidate. These modifications are thought to improve the peptide’s stability and potency [10].
Before buying Semax or N-Acetyl Semax Amidate for research purposes, it’s important to consider this peptide’s benefits, side effects, contraindications, and legal status.
