Marcus Reid is a functional medicine researcher, data analyst, and peptide specialist, and one of the people who built MyPeptidePal. The platform exists in part because of the years he spent immersed in clinical literature, real-world protocols, and the kind of hands-on experimentation that most textbooks skip entirely. He is not a physician and does not pretend to be. What he is, is someone who has done the work to understand how these compounds actually function at a biological level, what the research actually says versus what the forums claim, and how to explain it in a way that makes sense to anyone willing to learn. At MPP, Marcus contributed to building the knowledge base, the protocol frameworks, and the research systems that power the platform. His work covers tissue repair, metabolic health, hormonal optimization, longevity, cognitive function, and cosmetic applications. When the science gets complicated, his job is to make it click.

6 Best Peptides for Liver Fibrosis

People researching peptides for liver fibrosis are looking at a wider field than most guides acknowledge, ranging from semaglutide, which became the first FDA-approved peptide for liver scarring in August 2025, to research-only compounds like BPC-157 and TB-500 that carry decades of animal data, all the way to peptide bioregulators rooted in Eastern European research traditions. This guide covers six compounds people are genuinely using or actively discussing for liver fibrosis, explaining what each one is, how it is used for this goal, and where its evidence honestly stands. The entries are ordered by how prominently each compound appears in research and real-world use, not as a ranking of one being better than another for any individual person.

7 Best Peptides for Cirrhosis

Cirrhosis sits at the severe end of liver disease, and no peptide has been proven to reverse established scarring in humans. That reality does not stop people from researching, discussing, and using peptides in this space, and the field of compounds actually in circulation is wider than most lists acknowledge. This guide covers seven peptides people genuinely reach for when facing cirrhosis or advanced liver fibrosis, from GLP-1 receptor agonists with real phase 3 trial data to research peptides like BPC-157 with meaningful animal evidence, to liver-specific bioregulators like Ovagen and Svetinorm whose evidence is almost entirely experiential. The entries are ordered by how prominently each compound appears in research and in real-world use, not as a ranking of one option over another, and the personalized decision belongs with a qualified clinician and the MyPeptidePal app.

6 Best Peptides for Sleep Apnea

Sleep apnea is one of the few health goals where the peptide field sorts itself into unmistakably clear tiers: one compound carries FDA approval and Phase 3 randomized controlled trial data specifically for obstructive sleep apnea, a second GLP-1 agent has moderate off-label supporting evidence, and several others sit at the level of theoretical interest or isolated anecdote with no clinical trial data for this condition. This guide covers the six peptides people actually use or discuss for sleep apnea, ordered by how prominently each appears in research and documented real-world use, not as a ranking of one being better than another for any individual. Tirzepatide leads because its clinical evidence for this goal is in a different category from everything else on the list, but the right compound for any person depends on their situation, their health history, and what a qualified provider helps them build.

6 Best Peptides for Pulmonary Fibrosis

Six peptides show up consistently in the pulmonary fibrosis research pipeline, community protocols, or both: one is in active Phase 2 clinical trials, two have solid preclinical animal and human tissue data, and three belong to a research tradition with theoretical lung or immune targeting. No peptide is FDA-approved for this condition and none has cleared a randomized controlled trial in IPF patients, so the evidence picture varies sharply from one compound to the next. The entries below are ordered by how prominently each appears across published research and documented real-world use, not as a recommendation of one compound over another. What to do with that information is a personalized question the MyPeptidePal app is built to help answer.

6 Best Peptides for Thrombosis & Blood Clots

When people search for peptides related to thrombosis and blood clots, the landscape is more complicated than most listicles let on. No peptide is currently approved to treat or prevent blood clots, and the two most commonly discussed compounds in community protocols, BPC-157 and TB-500, have no published evidence specifically demonstrating anti-thrombotic efficacy. What does exist is a set of six peptides that appear in research or real-world discussion in the context of vascular health, blood vessel repair, inflammation, and the coagulation cascade itself. This guide covers each one honestly, from research-pipeline compounds like FXII900 that target clot formation directly to the recovery-focused peptides that appear in community forums. The entries are ordered by how prominently each shows up in research and real-world discussion, not as a recommendation of one over another, and standard anticoagulant therapy remains the only proven treatment for active thrombosis.
