Sigumir
Sigumir stands as the foundational Cytomax natural bioregulator for total skeletal and articular regeneration. Comprising complex peptide fractions extracted from the pristine cartilage and bone matrix of young animals, it is heavily relied upon by performance athletes and anti-aging physicians alike. It operates to aggressively reverse the brutal progression of osteoarthritis, violently halt osteoporotic bone loss, and dynamically rebuild destroyed joint capsules without the need for synthetic intervention.

Scientific Data
Mechanism of Action
Sigumir (A-4) is a Cytomax natural polypeptide extract from the cartilage and bone tissue of young calves, targeting human chondrocytes, osteoblasts, and synovial cells to restore the gene expression governing collagen matrix synthesis, proteoglycan production, and anti-inflammatory joint signaling. Osteoarthritis affects approximately 250 million people globally and is fundamentally a disease of cartilage degradation: chondrocytes (cartilage cells) progressively lose their ability to synthesize type II collagen and aggrecan (the proteoglycan that gives cartilage its compressive strength), while simultaneously upregulating matrix metalloproteinases (MMP-13, ADAMTS-5) that degrade the extracellular matrix.
Sigumir delivers short peptide signals (<10 kDa) from bovine cartilage and bone tissue. These peptides enter chondrocyte and osteoblast nuclei to reactivate age-silenced genes encoding: type II collagen (COL2A1), aggrecan (ACAN), SOX9 (the master transcription factor for chondrocyte differentiation), and anti-inflammatory cytokines (IL-1Ra, which directly blocks the cartilage-destructive IL-1β signaling). Unlike glucosamine/chondroitin supplementation (which provides building block substrates), Sigumir works at the transcription level — it tells chondrocytes to re-express the genes for building these molecules.
In Khavinson's protocol, Sigumir (A-4, cartilage/bone) is combined with Gotratix (A-18, skeletal muscle) and Bonomarlot (A-20, bone marrow) to create the complete locomotor system protocol addressing cartilage, muscle, and blood cell regeneration simultaneously.
