Bronchogen

Bronchogen is a Khavinson bioregulator tetrapeptide (AEDL) with primary effects on the bronchopulmonary system. Developed at Russia's St. Petersburg Institute of Bioregulation and Gerontology by Professor Vladimir Khavinson, it targets bronchial tissue and supports respiratory function. Like other Khavinson peptides, Bronchogen penetrates cell nuclei to influence gene expression related to respiratory tissue maintenance and repair.

COA Verified

Purity: ≥98% (HPLC verified)

Chonluten

Chonluten is a Khavinson bioregulator tripeptide (EDG) derived from respiratory lung tissue. Developed at Russia's St. Petersburg Institute of Bioregulation and Gerontology, it targets the bronchopulmonary system with secondary activity in the GI tract. Research shows it regulates genes related to inflammation, antioxidant activity, and proliferation responses. Chonluten inhibits TNF production in monocytes and has been studied as a potential geroprotective agent that may support lung function in conditions like COPD.

Crystagen

Crystagen is a Khavinson bioregulator tripeptide (EDP) identified in thymalin with selective action on thymus tissues. Developed at Russia's St. Petersburg Institute of Bioregulation and Gerontology, it enhances immune function by stimulating normal lymphocyte proliferation while inhibiting tumor cell growth. Research shows effectiveness in normalizing immunity in 82% of elderly patients (vs 56% control) and reducing respiratory infections in athletes by doubling HSP gene expression.

COA Verified

Purity: ≥98% (HPLC verified)

KPV

KPV is a potent anti-inflammatory tripeptide derived from the C-terminal of alpha-MSH. It exhibits remarkable anti-inflammatory and antimicrobial properties without the pigmentation effects of full α-MSH, making it ideal for inflammation management.

COA Verified

Purity: ≥98% (HPLC verified)

LL-37

LL-37 is the only human cathelicidin antimicrobial peptide, a 37-amino acid cationic peptide derived from hCAP18 that exhibits broad-spectrum antimicrobial activity against bacteria, viruses, and fungi while modulating immune responses.

COA Verified

Purity: ≥98% (HPLC verified)

Thymalin

Natural peptide bioregulator derived from calf thymus gland, developed in the Soviet Union in the 1970s. Contains a mixture of thymic peptides that support immune restoration, anti-aging, and tissue regeneration.

COA Verified

Purity: ≥98% (HPLC verified)

Thymosin Alpha-1 (Tα1)

Synthetic 28-amino acid peptide identical to naturally occurring thymic hormone, studied in 11,000+ patients across 30+ clinical trials with less than 1% serious adverse events. Approved in 35+ countries for immune modulation.

COA Verified

Purity: ≥98% (HPLC verified)

Vilon

Khavinson bioregulator dipeptide (KE) consisting of lysine and glutamic acid, originally isolated from thymus gland extracts. Acts as a molecular signaling compound that restores normal gene expression and protein synthesis in immune and epithelial cells.

COA Verified

Purity: ≥98% (HPLC verified)

VIP (Vasoactive Intestinal Peptide)

28-amino acid neuropeptide belonging to the glucagon/secretin superfamily. Produced in many tissues including the gut, pancreas, and brain. Has potent vasodilatory, anti-inflammatory, and immunomodulatory effects.

COA Verified

Purity: ≥98% (HPLC verified)
