Alternatives to VIP (Vasoactive Intestinal Peptide)

Lactoferricin is an antimicrobial peptide derived from lactoferrin, a protein found in milk and other secretions. It has potent antibacterial, antiviral, and antifungal properties.

Thymalin is a polypeptide preparation derived from calf thymus. Developed in Russia, it has been used for decades to support immune function and has shown potential anti-aging effects in long-term studies.

Mod GRF 1-29 (Modified GRF 1-29, also called CJC-1295 without DAC or Tetrasubstituted GRF 1-29) is a modified growth hormone-releasing hormone analog with improved stability over natural GHRH.

Human Growth Hormone (somatropin) is a 191-amino acid protein identical to naturally produced GH. FDA-approved for growth hormone deficiency, Turner syndrome, and other conditions. Widely used off-label for anti-aging and performance.

Alpha-defensins are small cationic peptides that are key components of the innate immune system. They have broad-spectrum antimicrobial activity against bacteria, fungi, and some viruses.

Thymulin (Facteur Thymique Sérique) is a zinc-dependent nonapeptide hormone produced by thymic epithelial cells. It plays important roles in T-cell differentiation and immune system maturation.

Octreotide (Sandostatin) is a synthetic somatostatin analog FDA-approved for acromegaly, carcinoid tumors, and VIPomas. It inhibits growth hormone and various GI hormones.

Sermorelin is a synthetic analog of GHRH consisting of the first 29 amino acids of the natural hormone. It was previously FDA-approved for GH deficiency diagnosis and treatment in children.

Pinealon is a short synthetic peptide developed from research on the pineal gland. It has shown neuroprotective and cognitive-enhancing properties in animal studies.

Epithalamin is a natural peptide extract from the pineal gland. It is the precursor compound from which the synthetic Epitalon was derived. Known for anti-aging and telomerase-activating properties.

NA-Selank Amidate (N-Acetyl Selank Amidate) is an enhanced version of Selank with improved stability and blood-brain barrier penetration. The modifications increase bioavailability and duration of cognitive and anxiolytic effects.

Oxytocin is a natural hormone produced in the hypothalamus, often called the 'love hormone' or 'bonding hormone.' It plays key roles in social bonding, childbirth, lactation, and stress regulation.

Growth Hormone Releasing Peptide 2 (GHRP-2) is considered one of the most potent GHRPs available. It provides strong GH release with moderate hunger increase compared to GHRP-6.

Semaglutide is a GLP-1 receptor agonist that has revolutionized weight management and diabetes treatment. FDA-approved as Ozempic (diabetes), Wegovy (weight loss), and Rybelsus (oral form), it has become one of the most prescribed peptides worldwide.

Delta Sleep-Inducing Peptide is a neuropeptide that promotes delta wave sleep, the deepest and most restorative phase of the sleep cycle.

CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH) that stimulates the pituitary gland to produce more growth hormone.

Ipamorelin is a selective growth hormone secretagogue that stimulates the release of growth hormone from the pituitary gland without significantly affecting cortisol or prolactin.

KPV is a tripeptide (Lys-Pro-Val) derived from alpha-melanocyte-stimulating hormone (α-MSH). It retains the potent anti-inflammatory properties of the parent hormone without the tanning or other melanocortin effects.

MK-677, also known as Ibutamoren, is an orally active growth hormone secretagogue. Unlike peptides, it can be taken orally and has a long half-life, providing 24-hour GH elevation.

Epitalon (Epithalon) is a synthetic tetrapeptide based on the natural peptide epithalamin, produced by the pineal gland. It is primarily studied for its effects on telomerase activation.
