Nootropic & Neuropeptides

FPF-1070, Cerebrolysin peptide preparation

A standardized mixture of low-molecular-weight peptides and free amino acids derived from purified porcine brain proteins, marketed by EVER Pharma in some countries as a neurotrophic agent and studied in ischemic stroke, dementia, and traumatic brain injury. It is not FDA- or EMA-approved, and systematic reviews report mixed and disputed evidence.

AEDP, Ala-Glu-Asp-Pro, H-Ala-Glu-Asp-Pro-OH, Cortagen tetrapeptide

A synthetic tetrapeptide (Ala-Glu-Asp-Pro, "AEDP") from Vladimir Khavinson's "short peptide bioregulator" school, derived by directed synthesis from the cerebral-cortex preparation cortexin and marketed as a brain/nervous-system "bioregulator." Evidence is limited, older, and almost entirely from the Khavinson lineage — rodent nerve-regeneration and ex-vivo chromatin studies, with no published human clinical trials. Not approved for human use.

Delta sleep-inducing peptide, Delta EEG-inducing peptide

A naturally occurring nonapeptide isolated in 1977 from the cerebral venous blood of sleeping rabbits. Despite its name, its sleep-promoting effects are inconsistent across studies and its physiological role, biosynthetic origin, and receptor remain unestablished. The evidence base is old, mixed, and largely preclinical.

EDR, EDR peptide, Glu-Asp-Arg, Cortagen-family cytogen

A synthetic tripeptide (Glu-Asp-Arg, "EDR") from Vladimir Khavinson's St. Petersburg school of short peptide bioregulators, marketed with a nootropic/neuroprotective framing. Its chemistry is well defined, but efficacy claims rest on cell, rodent, and limited, older, single-group human data with no independent replication. Not approved by the FDA or EMA for any use.

TP-7

A synthetic heptapeptide analog of the endogenous immunopeptide tuftsin, studied largely in Russian research for anxiolytic, nootropic, and immunomodulatory effects. Not approved by the FDA or EMA.

ACTH(4-10) Pro-Gly-Pro analog, ACTH(4-7)PGP, Met-Glu-His-Phe-Pro-Gly-Pro

A synthetic heptapeptide derived from a fragment of ACTH, developed and registered in Russia and studied for nootropic and neuroprotective effects, with research most often linking it to BDNF signaling. Most evidence is Russian and not replicated in large Western trials.
