Your Complete Guide to the Maxx Labs Peptide Lineup
Not all peptides are created equal — and knowing exactly what each one does can make all the difference in how you approach your research. Maxx Labs offers a carefully curated range of research-grade peptides, each with its own unique mechanism of action, target pathway, and body of scientific literature behind it.
Below is a complete, plain-language breakdown of every peptide in the Maxx Labs catalog, so you know precisely what you're working with.
BPC-157: The Repair and Recovery Peptide
BPC-157 (Body Protection Compound-157) is a 15-amino-acid peptide derived from a protective protein found in gastric juice. It is among the most researched peptides in the current literature, with a wide range of studied biological activities.
Research suggests BPC-157 may support tissue repair, tendon-to-bone healing, and gut lining integrity. Studies published in Journal of Physiology-Paris and similar journals indicate it may modulate nitric oxide pathways and promote angiogenesis — the formation of new blood vessels — which researchers believe underlies many of its observed effects in animal models.
Key research areas: musculoskeletal recovery, gut health, inflammation modulation.
TB-500 (Thymosin Beta-4): The Cellular Mobility Peptide
TB-500 is a synthetic version of Thymosin Beta-4, a naturally occurring peptide found in virtually all human and animal cells. Its primary mechanism involves actin regulation — actin being the protein responsible for cell structure and movement.
Studies indicate TB-500 may support wound healing, reduce localized inflammation, and promote tissue regeneration. A key distinction from BPC-157 is TB-500's systemic reach: because it regulates actin throughout the body, researchers observe effects across multiple tissue types simultaneously.
Key research areas: wound healing, cardiac tissue, systemic recovery support.
CJC-1295 + Ipamorelin: The Growth Hormone Secretagogue Stack
These two peptides are frequently studied together because they work on complementary pathways. CJC-1295 is a GHRH (Growth Hormone Releasing Hormone) analogue that extends the signal telling the pituitary to produce growth hormone. Ipamorelin is a selective GHRP (Growth Hormone Releasing Peptide) that mimics ghrelin to stimulate GH release without significantly raising cortisol or prolactin levels.
Research suggests this combination may produce a more sustained and physiologically balanced growth hormone pulse compared to either peptide alone. Studies indicate potential support for lean body composition, sleep quality, and recovery-related pathways in research subjects.
Key research areas: GH axis modulation, body composition research, sleep architecture.
GHK-Cu: The Copper Peptide for Skin and Cellular Health
GHK-Cu is a naturally occurring copper-binding tripeptide (Glycine-Histidine-Lysine) found in human plasma, saliva, and urine. Its concentration declines significantly with age, making it a subject of great interest in longevity and dermatological research.
Research suggests GHK-Cu may support collagen synthesis, skin barrier function, and antioxidant gene expression. A 2018 review in Biomolecules highlighted its potential role in resetting gene expression patterns associated with aging. It is one of the few peptides with substantial in-vitro and in-vivo research across both topical and systemic applications.
Key research areas: skin regeneration, collagen production, gene expression, anti-aging biology.
Thymosin Alpha-1 (TA1): The Immune Modulation Peptide
Thymosin Alpha-1 is a 28-amino-acid peptide derived from the thymus gland — the organ most responsible for T-cell maturation and immune education. It has been researched extensively in the context of immune system support and has been studied in clinical settings internationally for decades.
Studies indicate TA1 may support T-cell activity, dendritic cell function, and the body's natural immune surveillance mechanisms. Researchers note particular interest in its potential as an adjunct in immunocompromised research models.
Key research areas: immune modulation, T-cell research, inflammatory response.
Epithalon: The Telomere Research Peptide
Epithalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed from research originating in Russia at the St. Petersburg Institute of Bioregulation. It is most widely studied for its potential to activate telomerase — the enzyme responsible for maintaining telomere length, which is closely associated with cellular aging.
Research suggests Epithalon may support telomere elongation in aged cell lines and may influence pineal gland function and circadian melatonin rhythms. It remains one of the most researched peptides in the longevity science space.
Key research areas: telomere biology, cellular aging, circadian rhythm, pineal regulation.
Semax: The Neuropeptide for Cognitive Research
Semax is a heptapeptide analogue of ACTH (adrenocorticotropic hormone) developed in Russia, where it has been studied extensively in neuroprotection and cognitive function research. It is known to influence BDNF (Brain-Derived Neurotrophic Factor) expression and dopaminergic activity.
Studies indicate Semax may support focus, memory consolidation, and neuroprotective mechanisms. Researchers are particularly interested in its potential role in models of cognitive stress and neuroinflammation.
Key research areas: cognitive function, BDNF modulation, neuroprotection, focus.
DSIP (Delta Sleep-Inducing Peptide): The Sleep Architecture Peptide
DSIP is a nine-amino-acid neuropeptide first isolated from rabbit brain tissue during slow-wave sleep states. As its name suggests, it has been studied primarily in the context of sleep regulation and stress modulation via the hypothalamic-pituitary axis.
Research suggests DSIP may support deeper slow-wave sleep stages, reduce stress-related hormonal dysregulation, and may interact with LH and GH secretion pathways. It represents a unique neuropeptide research area at the intersection of sleep science and neuroendocrinology.
Key research areas: sleep quality research, stress hormone modulation, HPA axis.
Why Peptide Purity and Quality Matter
Every peptide in the Maxx Labs lineup is manufactured to research-grade standards, with purity verified by HPLC (High-Performance Liquid Chromatography) testing. Peptide stability, storage temperature, and reconstitution protocols all affect the integrity of research outcomes — which is why sourcing from a verified supplier matters.
All Maxx Labs peptides come with a Certificate of Analysis (COA) and are intended strictly for in-vitro and preclinical research use.
