Understand the mechanisms being studied, the evidence available, and the questions that remain open.
NeuroscienceCerebrolysin is a porcine brain-derived preparation containing a mixture of peptides and other components. It is not one defined synthetic peptide. It has been investigated in neurological conditions and used in some jurisdictions, but United States readers need to distinguish that history from FDA approval.
NeuroscienceDihexa is an experimental angiotensin IV-related peptidomimetic studied in nervous-system models. Online accounts often use dramatic potency comparisons to imply exceptional cognitive benefit. A laboratory potency statement is not a measure of improvement in a person’s memory or daily functioning.
NeuroscienceDSIP stands for delta sleep-inducing peptide, also called emideltide. The name suggests a sleep effect but should not be treated as evidence of a reliable insomnia treatment. The human literature is limited and includes small studies with cautious conclusions.
NeuroscienceHumanin is a short peptide associated with mitochondrial signaling and cellular stress responses. It was identified through work investigating protection from selected neuronal-cell insults. It is a research subject rather than a proven consumer treatment for dementia, fatigue, or aging.
NeuroscienceOxytocin is an endogenous peptide hormone with established roles in childbirth and lactation. Regulated oxytocin injections also have specific obstetric uses. Popular descriptions as a love or trust hormone oversimplify the biology and do not establish a general mood or social-wellness treatment.
NeurosciencePinealon is a short synthetic tripeptide studied as a regulatory peptide. It appears in discussions of neuronal stress and aging, but those research themes do not establish an effective treatment for memory loss, insomnia, or general brain health.
NeuroscienceSelank is a synthetic heptapeptide related to the tuftsin sequence and studied for anxiety-related and other nervous-system effects. It is often marketed as a calming nootropic. Such descriptions should be separated from verified clinical evidence and from United States regulatory approval.
NeuroscienceSemax is a synthetic heptapeptide derived from an ACTH-related sequence and studied for nervous-system effects. It is frequently described online as a nootropic. That label is a marketing category, not proof of improved cognition or a reviewed United States medical indication.
