Khavinson-class tetrapeptide bioregulator (Ala-Glu-Asp-Arg) studied for cardiomyocyte gene regulation, anti-apoptosis, and cardiac tissue support in Russian bioregulator literature.

GHRH analog that stimulates natural growth-hormone pulses; used with GHRPs for body composition and recovery goals.

The default growth-hormone peptide stack in biohacking: GHRH analog + selective GHRP for physiologic pulses.

Long-acting GHRH analogue form of CJC-1295 using Drug Affinity Complex for multi-day GH/IGF-1 elevation research framing.

Khavinson tetrapeptide bioregulator (Ala-Glu-Asp-Pro) developed as a cerebral-cortex-targeted short peptide for neuroprotection and cortical gene regulation research.

Khavinson immune/thymus-focused short peptide bioregulator commonly cited as Glu-Asp-Pro (EDP), positioned as a synthetic counterpart within the thymic bioregulator family alongside Thymalin.

Synthetic tetrapeptide from Russian bioregulator research, claimed to influence telomerase and circadian rhythms.

Synthetic D-retro-inverso peptide designed to disrupt FOXO4–p53 interaction, studied as a senolytic that selectively clears senescent cells in preclinical models.

Naturally occurring copper-binding tripeptide popular for skin remodeling, hair, and regenerative aesthetics.

Tripeptide antioxidant (Glu-Cys-Gly) central to cellular redox defense; used IV in clinics and discussed for skin brightening and detox narratives.

Mitochondrial-derived peptide studied for cytoprotection, metabolism, and neuroprotection.

Mitochondria-encoded peptide linked to exercise-mimetic metabolic regulation in research.

Not a peptide, but central to biohacking stacks often combined with mitochondrial peptides and clinic IVs.

Orally bioavailable CNTF-derived tetrapeptide (adamantylated) that enhances BDNF signaling, neurogenesis, and reduces tau/Aβ pathology in Alzheimer's mouse models.

Short bioregulator peptide from the Khavinson group aimed at brain and pineal support.

Chimeric peptide combining a p53 HDM-2-binding segment with a membrane-penetration motif; studied for selective cancer cell membrane disruption in preclinical oncology research.

GHRH (1-29) analog historically used diagnostically and therapeutically to stimulate endogenous GH.

Mitochondria-targeting tetrapeptide (elamipretide) studied for bioenergetic and rare disease indications.

Thymic peptide preparation (and related thymulin nonapeptide) from the Khavinson/Russian thymic medicine tradition used for immunosenescence and immune reconstitution research.

Immune-modulating peptide used clinically in some countries for hepatitis and as an immune adjuvant.
