Subjective Outcome
6 compoundsin Regimen’s catalog are configured to track focus via Rate Today. Each one shows the dose range, listed benefits, and every outcome it’s set up to monitor. Tap through to plan a dose with the free reconstitution calculator.
Peptides marketed for focus and cognition (semax, selank, dihexa, cerebrolysin) have an evidence base concentrated in Russian and Eastern European literature. Western placebo-controlled trials are limited. Semax (a fragment of ACTH 4–10) has been studied for stroke recovery and anxiety with positive but small-sample results; selank (a tuftsin analog) has anxiolytic data in similar contexts.
Outside the dedicated nootropic peptide class, focus improvements are often downstream of other inputs: TRT in hypogonadal men can improve cognitive function modestly; GH secretagogues improve sleep which improves next-day cognition; and addressing thyroid deficiency produces large focus gains.
Anyone considering nootropic peptides should understand that the evidence is thin, formulation quality varies widely, and there is no FDA-approved peptide in this category. Tracking focus subjectively over a protocol cycle is the most pragmatic way to evaluate whether a given compound is working for you.

Intranasal Social-Bonding Neuropeptide
A nine-amino-acid neuropeptide explored in research as an intranasal spray for social cognition, anxiety, and bonding effects. This entry reflects research-protocol intranasal microdosing only — distinct from obstetric IV oxytocin used during labor.
Tracks
Khavinson Pineal-Derived Tripeptide
A synthetic tripeptide (Glu-Asp-Arg) from Khavinson's bioregulator program at the St. Petersburg Institute of Bioregulation. Animal studies report reduced ROS in cerebellar granule and PC12 cells, plus improved cognitive outcomes in prenatal hyperhomocysteinemia and Alzheimer's mouse models.
Tracks
Angiotensin IV-Derived c-Met Activator
An orally bioavailable, blood-brain-barrier-penetrant hexanoyl-modified analog of angiotensin IV that potentiates the hepatocyte growth factor (HGF) / c-Met system. Preclinical work reports synaptogenesis at picomolar concentrations and reversal of scopolamine-induced cognitive deficits in rodents.
Tracks
28-aa Anti-Inflammatory Neuropeptide
A 28-amino-acid neuropeptide signaling through VPAC1/VPAC2 receptors. Established anti-inflammatory and immunomodulatory effects across innate and adaptive immunity. Used clinically off-label as an intranasal preparation in chronic inflammatory response syndrome (CIRS) protocols.

There is no peptide with Western RCT evidence as strong as the data for, say, modafinil or methylphenidate. Semax and selank have positive small-sample evidence from non-Western trials. Dihexa has compelling preclinical data but no human trials. For most users, the largest cognitive gains come from fixing sleep, hormone deficiencies, and metabolic health — not from a dedicated nootropic peptide.
Subjective scoring across a cycle is the most practical approach. Regimen’s Rate Today logs focus on a 1–5 scale daily, and the 30-day sparkline shows trajectory next to your dose log. Pair that with one objective task — a chess.com rating, a Lumosity score, a typing speed test — to triangulate.
The safety profile of most nootropic peptides is poorly characterized in long-term human use. Many are sold as research chemicals rather than pharmaceuticals, formulation quality varies, and contamination is a real risk. If you proceed, source matters more than dose, and a prescriber-supervised protocol with periodic bloodwork is the safer path.
