Peer-style reviews of the peptide research record — mechanisms, safety data, and clinical context. Editorial, not promotional. Cite the originals; we only summarize.
Research peptides are short amino acid chains studied for their biological activity in preclinical research. This guide explains what they are, how they work, how they differ from drugs, and what the regulatory landscape means for researchers.
Read the review →What separates a supplier worth ordering from on purity testing, documentation and handling, and the signals that should stop an order.
What each section of a CoA actually certifies, which numbers matter, and the common ways a document can look reassuring while saying very little.
What a purity percentage does and does not tell you, how the measurement is made, and why two identical-looking figures can mean different things.
Lyophilised and reconstituted stability, temperature exposure in transit, and the handling practices that preserve a compound's integrity.
The practical differences in testing regimes, transit conditions, documentation and recourse between domestic and overseas sourcing.
A checklist for evaluating a supplier: third-party testing, batch documentation, storage and shipping practice, and transparency.
A comprehensive review of Body Protection Compound 157's healing properties, proposed mechanisms, gastrointestinal and musculoskeletal evidence, CNS effects, and the critical open questions regarding human translation.
BPC-157 has one of the largest preclinical evidence bases of any research peptide, but no published human trials. This safety-focused guide reviews what is known about its adverse event profile, toxicity data, and the real risks of unregulated sourcing.
TB-500 and BPC-157 are the two most widely studied healing peptides. They share overlapping outcomes in animal models but operate through entirely different mechanisms. This comparison examines what each does, where they differ, and why researchers often study them together.
GHK-Cu (copper peptide) is one of the few research peptides with a substantial human-relevant evidence base for skin aging. This review covers what the research actually shows: collagen synthesis, wound healing, hair growth, and the limits of current evidence.
An analysis of the two most studied GH-axis peptides: their complementary mechanisms, synergy rationale, what the research shows about physiological effects, and the safety considerations relevant to their use.
Examining the neuropharmacology of two Russian-developed neuropeptides: their distinct mechanisms, clinical approval status in Russia, BDNF upregulation, anxiolytic effects, and the evidence available for Western researchers.
Mitochondria-derived peptides (MDPs) represent a new paradigm in cellular signaling. This review covers the three most studied MDPs, their mechanisms, clinical trial data, and the open questions around aging and metabolic disease research.
Melanotan II is an unlicensed tanning peptide associated with a range of serious adverse events including melanoma cases, priapism, cardiovascular reactions, and deaths. Multiple regulatory agencies worldwide have issued warnings and enforcement actions.
What tesamorelin is, how the stabilised GHRH(1-44) analogue differs from other growth hormone secretagogues, and what the published human trials actually measured.
What a research peptide blend is, why BPC-157, TB-500, GHK-Cu and KPV are combined, and what a certificate of analysis can and cannot tell you about a multi-peptide vial.
How single, dual and triple incretin receptor agonists differ, why lipidation gives them multi-day half-lives, and what the published human trials measured.
What thymosin alpha-1 and thymalin are, how a defined 28-residue peptide differs from an undefined thymic extract, and what separates their evidence bases.
What the short peptide bioregulators are, where the epithalon telomerase claims actually come from, and why the evidence is thinner than its reputation.

The articles below are reviews of the published peptide literature, written for qualified researchers and the technically curious. They describe mechanisms, preclinical data, regulatory status, and safety records — they do not contain dosing protocols, administration instructions, or therapeutic recommendations. Where a compound is sold by Luxpeptide, the article links to the corresponding research-grade reference page; this is not an endorsement of any therapeutic claim and is not medical advice. Statements have not been evaluated by the FDA. Products are not intended to diagnose, treat, cure, or prevent any disease, and are not for human or animal consumption.
