Thymosin Beta-4 is a 43-amino-acid peptide that your body naturally produces to orchestrate healing. It promotes blood vessel formation, reduces scarring (fibrosis), and protects tissues from damage. It's particularly valued for heart recovery after injury and reducing inflammation throughout the body. Think of TB-500 as a fragment of this larger, more comprehensive healing molecule.
What it is
Thymulin is a natural hormone produced by your thymus gland that declines with age. It's essential for training and maturing your T-cells - the soldiers of your immune system. By supplementing thymulin, you can help restore youthful immune function, reduce excessive inflammation, and support recovery from illness or chemotherapy. It requires zinc to work properly.
What it is
Thyreogen is a bioregulator peptide extracted from thyroid tissue that helps normalize your thyroid hormone production (T3 and T4). Rather than replacing hormones, it works by restoring the genes and pathways that control thyroid function. This makes it useful for people with sluggish thyroids, metabolic slowdown, or those recovering from thyroid stress.
What it is
Tirzepatide is a breakthrough dual-action peptide that activates both GLP-1 and GIP receptors - two key hormones that control blood sugar and appetite. It's the most effective weight loss medication available, helping people lose 20%+ of their body weight in clinical trials. It also dramatically improves blood sugar control and may protect your heart. FDA-approved as Mounjaro.
What it is
Triptorelin is a powerful GnRH analog used medically to control sex hormone levels. It initially stimulates hormone production but with continued use causes the pituitary to downregulate, dramatically reducing testosterone or estrogen. It's FDA-approved for prostate cancer, endometriosis, precocious puberty, and gender-affirming care.
What it is
VIP is a versatile 28-amino-acid neuropeptide that acts as a master regulator of inflammation throughout your body. It protects the brain, heals the gut, supports lung function, and calms overactive immune responses. It's particularly effective for Chronic Inflammatory Response Syndrome (CIRS), mold illness, and complex multi-system inflammatory conditions.
What it is
Ventfort is a bioregulator peptide derived from blood vessel tissue that helps restore the health of your arteries and veins. It works by enhancing nitric oxide production for better blood flow, promoting arterial elasticity, and reducing vascular inflammation. Ideal for people with cardiovascular risk factors or age-related circulation decline.
What it is
Vesilut is a bioregulator peptide extracted from bladder tissue that helps heal and restore bladder function. It reduces inflammation, repairs the bladder lining, and improves neuromuscular control of the bladder. Particularly helpful for chronic bladder irritation, interstitial cystitis, and age-related urinary issues.
What it is
Vesugen is a synthetic tripeptide (Lys-Glu-Asp) that specifically targets the endothelium - the inner lining of your blood vessels. It reverses age-related declines in vascular elasticity, enhances nitric oxide production, and supports both cardiovascular and cognitive health by improving blood flow throughout the body.
What it is
Vilon is a synthetic dipeptide (lysine-glutamic acid) that enhances immune function while reducing signs of aging. It works by balancing cytokines, promoting tissue repair, and activating longevity genes. Despite its simple structure, it has powerful effects on immune coordination and cellular regeneration.
What it is
Visoluten is a bioregulator peptide derived from eye tissue that supports retinal and optic nerve health. It protects photoreceptors, reduces eye inflammation, and stabilizes the blood-retinal barrier. Ideal for people with age-related vision changes, macular degeneration, or those wanting to protect their eyes from screen strain.
What it is
Vladonix is a bioregulator peptide derived from thymus tissue that restores immune balance during aging. It supports T-cell maturation and differentiation, reduces chronic inflammation, and strengthens your body's defense mechanisms. Particularly valuable for people experiencing immune decline with age.
What it is
Zhenoluten is a bioregulator peptide derived from ovarian tissue that helps restore hormonal balance and ovarian function. It works by enhancing the genes that control follicular development and hormone production. Particularly valuable for women experiencing premature ovarian decline, perimenopause, or fertility challenges.
