Peptides, explained.
What the peptide research actually shows — and where the gaps are. Evidence-first reads, from first principles to the compounds everyone argues about.
What are peptides?
Short chains of amino acids — the body's own signaling molecules. A clean definition, and what researchers look for.
Peptides vs. proteins vs. amino acids
Related, but not the same. How amino acids, peptides, and proteins differ in size and structure — and why the distinction matters.
How peptides work in the body
They send signals. How peptides bind receptors, the four main mechanisms, and why short half-lives and the blood-brain barrier shape the research.
A beginner's guide to peptide research
What to look for, what questions to ask, and how to think about responsible peptide research — from legal status to sourcing to documentation.
BPC-157: what the research says about tissue repair
One of the most studied peptides in tissue repair — and one of the most misunderstood. What the research actually shows, and what it doesn't.
TB-500 (Thymosin Beta-4) and wound healing
BPC-157's most-debated counterpart. What the wound-healing research shows, where the human data sits, and how the two compounds compare.
CJC-1295 & Ipamorelin: the GH peptide stack
The most commonly studied growth hormone peptide combination. How each works, why they're paired, and what the evidence does and doesn't support.
Peptides and exercise recovery: what science shows
Recovery is one of the most common reasons people look into peptides. Cutting through the hype — what the research supports, and where the gaps are.
The "Wolverine Stack": BPC-157, TB-500 & CJC-1295
Few names in peptide research generate more curiosity — or confusion. What the stack actually is, the rationale, and what we know versus what we don't.
GLP-1 peptides: semaglutide, Ozempic & the research
The most written-about peptide class in the world. What they are, how they work, what the research shows, and where the open questions remain.
AOD-9604: the fat-burning peptide, fact-checked
A growth-hormone fragment with a complicated history and a lot of online misinformation. What the research shows — and what it doesn't.
Peptides and metabolism: what the studies show
Metabolism is one of the most misused words in health and wellness. What it actually is, and which peptides the research connects to it.
Why metabolic health is the foundation of everything
You can train, sleep and supplement wisely — but if your metabolism isn't working, much of that effort doesn't translate.
NAD+ and NMN: the science of cellular energy and aging
No area of longevity research has generated more excitement — or more hype — than NAD+ and its precursors. Here's what the evidence supports.
Epithalon: the telomere research peptide
No peptide carries more longevity folklore than Epithalon. The actual evidence, the actual gaps, and the actual state of the research.
Senolytics vs. peptides: two approaches to aging research
Two approaches dominate longevity research: senolytics that clear aged cells, and peptides that modulate repair. How they compare.
How peptides may support cellular repair and regeneration
The body's capacity for repair is remarkable — until it isn't. Here's what we know about modulating it, and where the evidence actually stands.
