Your Complete Guide to Every Maxx Labs Research Peptide

Not all peptides are created equal, and not all peptide brands explain what they actually sell. At Maxx Labs, transparency is the foundation. Whether you are a seasoned biohacker or just beginning to explore peptide research, this guide breaks down every product in the Maxx Labs lineup so you know exactly what you are working with.

Each peptide below includes its amino acid origin, what the current body of research suggests about its mechanisms, and why researchers and wellness-focused individuals have taken a close interest in it.

Repair and Recovery Peptides

BPC-157 (Body Protection Compound 157)

BPC-157 is a 15-amino-acid peptide derived from a naturally occurring protein found in gastric juice. Research suggests it may support tissue repair processes, particularly in tendons, ligaments, and gut lining. A 2018 study published in Journal of Applied Physiology indicated that BPC-157 may influence nitric oxide synthesis and angiogenesis pathways, two key drivers of healing response.

Studies in animal models also indicate it may support gastrointestinal integrity. Researchers studying gut health, connective tissue recovery, and inflammatory response have made BPC-157 one of the most widely studied peptides in the field. Bpc 157

TB-500 (Thymosin Beta-4 Synthetic Analog)

TB-500 is a synthetic analog of Thymosin Beta-4, a naturally occurring peptide found in nearly all human and animal cells. It is composed of 43 amino acids. Research suggests TB-500 may play a role in actin regulation, which is fundamental to cell migration and tissue regeneration.

Studies indicate it may support recovery from muscle and soft tissue stress, and animal model research has explored its potential effects on blood vessel formation. It is frequently studied alongside BPC-157 for its complementary mechanism profile. Tb 500

Growth Hormone Secretagogues

CJC-1295 (with DAC)

CJC-1295 is a 30-amino-acid Growth Hormone Releasing Hormone (GHRH) analog. The version with Drug Affinity Complex (DAC) extends its half-life to approximately 6-8 days by binding to albumin in the bloodstream. Research suggests CJC-1295 may stimulate the pituitary gland to increase growth hormone pulse frequency.

Studies published in the Journal of Clinical Endocrinology and Metabolism have noted elevated IGF-1 levels in subjects following administration. Researchers studying body composition, recovery, and sleep quality often pair it with a GHRP for synergistic effect.

Ipamorelin

Ipamorelin is a selective Growth Hormone Releasing Peptide (GHRP) composed of 5 amino acids. Unlike older GHRPs, research suggests Ipamorelin may stimulate GH release with minimal impact on cortisol or prolactin levels, making it a cleaner secretagogue in terms of hormonal selectivity.

It works on ghrelin receptors in the pituitary gland. Studies indicate it may support lean tissue, recovery cycles, and sleep architecture when used in research protocols. It is commonly studied in combination with CJC-1295. Cjc 1295 Ipamorelin

Skin and Cellular Health Peptides

GHK-Cu (Copper Peptide)

GHK-Cu is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. Levels are known to decline significantly with age. Research suggests GHK-Cu may support collagen synthesis, wound repair signaling, and antioxidant activity at the cellular level.

A 2015 review in Biomolecules highlighted GHK-Cu's potential role in gene expression regulation, noting it may influence over 4,000 genes associated with tissue remodeling and anti-inflammatory pathways. Researchers studying skin biology and cellular aging have given it considerable attention. Ghk Cu

Epithalon (Epitalon)

Epithalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) derived from the natural peptide Epithalamin, produced in the pineal gland. Research suggests it may support telomerase activation, the enzyme responsible for maintaining telomere length in chromosomes.

Studies in animal models and cell lines indicate Epithalon may support healthy aging markers and circadian rhythm regulation. It is one of the more actively researched longevity-focused peptides in the current scientific literature.

Immune and Cognitive Peptides

Thymosin Alpha-1 (TA1)

Thymosin Alpha-1 is a 28-amino-acid peptide naturally secreted by the thymus gland. Research suggests it may support T-cell maturation, dendritic cell function, and overall immune system signaling. Studies indicate it may enhance the body's response to immune challenges by modulating cytokine activity.

It has been studied extensively in the context of immune regulation and has been the subject of over 70 published clinical investigations globally. Researchers focused on immune health and inflammatory response consider TA1 a foundational peptide. Thymosin Alpha 1

Semax

Semax is a heptapeptide analog of ACTH (adrenocorticotropic hormone), originally developed in Russia and studied extensively in Eastern European research institutions. Research suggests it may support BDNF (Brain-Derived Neurotrophic Factor) expression, which plays a key role in neuronal health and synaptic plasticity.

Studies indicate Semax may support cognitive performance, focus, and stress resilience in animal models. Researchers studying neuroprotection and cognitive function have made it a subject of growing international interest.

Selank

Selank is a synthetic analog of the immune peptide Tuftsin, consisting of 7 amino acids. Research suggests it may influence serotonin, dopamine, and GABA neurotransmitter systems. Studies indicate it may support anxiolytic-like responses and mood stability without sedative side effects observed in other compounds.

It has been the subject of multiple studies from the Russian Academy of Sciences, where it was originally developed. Researchers interested in stress response and neurochemical balance have explored it as a nootropic peptide candidate.

Why Research Grade Purity Matters

Every Maxx Labs peptide is manufactured to research-grade standards with third-party HPLC (High-Performance Liquid Chromatography) purity testing. Peptide integrity depends on amino acid sequence accuracy, proper lyophilization, and controlled storage conditions. Maxx Labs provides Certificates of Analysis (COAs) for every batch so researchers can verify exactly what they are working with.

Impure or mislabeled peptides compromise research outcomes. Purity is not optional, it is the baseline. Third Party Testing
