Longevity

AHK-Cu

Human-limited

Copper peptide for skin regeneration and repair

AHK-Cu is a copper-binding tripeptide (Ala-His-Lys) complexed with copper(II) ions, closely related to the well-studied GHK-Cu peptide. It stimulates collagen and glycosaminoglycan synthesis in skin fibroblasts while exerting antioxidant and anti-inflammatory activity. Primarily researched in the context of skin regeneration, wound healing, and hair follicle stimulation.

Cardiogen

Human-limited

Cardiac peptide bioregulator for heart longevity

Cardiogen is a short synthetic tetrapeptide (Ala-Glu-Asp-Arg) originally developed by the St. Petersburg Institute of Bioregulation and Gerontology in Russia, designed to support cardiac tissue health and function. It acts as a cytoprotective bioregulator targeting cardiomyocytes, promoting cellular repair and reducing age-related deterioration in heart muscle tissue. Research, primarily from Russian preclinical and limited clinical studies, suggests it may help maintain cardiac contractility, reduce fibrosis, and support overall cardiovascular resilience.

Thymalin/Thymulin

Human-limited

Thymic peptide restoring immune vitality with age

Thymalin is a thymic peptide preparation derived from calf thymus glands, while Thymulin (FTS) is a naturally occurring nonapeptide produced by thymic epithelial cells that requires zinc as a cofactor for biological activity. Together they represent thymic-origin immunomodulatory compounds that restore and regulate T-lymphocyte differentiation, maturation, and function. They are used primarily to support immune system integrity, combat immunosenescence, and may have applications in anti-aging and recovery protocols.

Cortagen

Animal

Pineal-derived peptide for brain and immunity

Cortagen is a synthetic tetrapeptide (Ala-Glu-Asp-Pro) derived from the pineal gland and developed within the Russian peptide bioregulator program. It is primarily studied for its neuroprotective and immunomodulatory properties, with research suggesting it may support cortical function, slow age-related neurological decline, and modulate immune responses. Most of its evidence base comes from Russian preclinical and limited clinical studies conducted in the 1980s–2000s.

FOXO4-DRI

Animal

Senolytic peptide targeting cellular senescence

FOXO4-DRI is a D-amino acid retro-inverso peptide designed to selectively induce apoptosis in senescent cells by disrupting the interaction between FOXO4 and p53. It belongs to a class of experimental senolytic compounds—agents that clear aged, dysfunctional 'zombie' cells from tissues. Research has been conducted primarily in mouse models, where it demonstrated improvements in fitness, fur density, kidney function, and lifespan metrics.
