About
Written by AI.
Sourced from research.
Trusted by design.
Who Made This
This project was prompted by Jack Butcher (Visualize Value) and authored by Claude, Anthropic's AI assistant. Every peptide profile, every mechanism description, every protocol summary — prompted by a human, written by AI, sourced from published research.
We're transparent about this because we believe it's a feature, not a bug. AI can synthesize research across hundreds of papers without the conflicts of interest that plague the peptide space — no inventory to sell, no affiliate commissions to earn, no brand partnerships to protect.
The Problem With Peptide Content
Search for any peptide online and you'll find vendor websites posing as educational resources. Forums full of anecdotal claims. Content farms regurgitating surface-level information with affiliate links attached. Even the "good" content is usually written by someone selling something.
The result: people making health decisions based on marketing copy disguised as science.
How This Works
Every peptide profile on this site follows the same rigorous structure: mechanism of action, published research with real citations, commonly used protocols clearly labeled, safety profiles, and practical information.
All claims are sourced from peer-reviewed journal articles, clinical trial data from PubMed and ClinicalTrials.gov, and established pharmacological references. When evidence is limited or primarily preclinical, we say so explicitly. When community protocols differ from research doses, both are presented and clearly distinguished.
What We Don't Do
- —Sell peptides or any products
- —Use affiliate links
- —Run ads
- —Provide medical advice
- —Hype unproven claims
- —Hide what wrote this
AI Limitations
AI authorship has real limitations and we acknowledge them. Claude's training data has a knowledge cutoff, which means very recent studies may not be reflected. AI can occasionally hallucinate details — we've verified citations and core claims, but errors are possible. This is a living resource that gets updated as we identify issues.
If you spot an error or outdated claim, we want to know. Accuracy matters more than anything else here.
The Standard
We believe AI-authored content held to a rigorous sourcing standard is more trustworthy than human-authored content with hidden commercial incentives. The peptide space needed a resource that prioritizes accuracy over revenue. This is that resource.
Changelog
Built in public.
Peptide Finder quiz, 2 more comparisons, category deep dives
Interactive "What should I use?" quiz that recommends peptides based on your goals. 2 new comparisons: CJC-1295 DAC vs No-DAC, Epitalon vs GHK-Cu. 6 total comparisons now. Every category page now has 200-300 words of substantive overview content. Compare page restructured as an index listing all comparisons.
ELI5 mode
Every peptide page now has a TLDR/ELI5 toggle. TLDR gives you the dense, factual version. ELI5 explains it like you're talking to a smart friend who knows nothing about science. 46 plain-English explanations written.
Comparisons, glossary, stacks guide, search upgrade, 4 more peptides
3 head-to-head comparison pages (BPC-157 vs TB-500, Ipamorelin vs GHRP-6, Semax vs Selank) with FAQ schema. 27-term glossary with DefinedTermSet schema. Peptide Stacking Guide covering 6 popular combinations. Fuzzy search upgrade with Fuse.js. Smooth scroll for TOC navigation. Custom 404 page. PG favicon. New peptides: Melanotan II, Thymulin, GHK (non-copper), SNAP-8. 46 peptides total.
SEO + AI visibility optimization
Ran full GEO (Generative Engine Optimization) audit. Fixed Cloudflare blocking all AI crawlers (GPTBot, ClaudeBot, PerplexityBot) via robots.txt. Submitted sitemap to Google Search Console and Bing Webmaster Tools. Added FAQ schema to comparison page for "People also ask" targeting. Configured llms.txt with complete site index for AI agent discovery. Every page now has MedicalWebPage, FAQPage, or CollectionPage JSON-LD schema.
Comparison page + 5 more peptides
Added Semaglutide vs Tirzepatide vs Retatrutide comparison page — targeting high-volume search queries. New peptides: DSIP, Orforglipron, Suramin, CJC-1295 DAC, Thymalin. Full peptides index page. 42 peptides, 118 pages total.
OG images + TLDRs + Retatrutide
Dynamic OG images for every page — black background, white Helvetica. TLDR summaries added to every peptide page. Added Retatrutide (Eli Lilly's triple agonist).
AI authorship positioning
Leaned into transparent AI authorship. Updated About page, footer, and every peptide page to credit "Prompted by Jack Butcher (Visualize Value) · AI-authored by Claude."
Guides + remaining peptides
Three practical guides: Reconstitution, Dosing 101, Peptide Safety. Added Thymosin Beta-4, Pentosan Polysulfate, Cerebrolysin, CJC-1295/Ipamorelin combo. Design polish pass — unified containers, fixed side effects table alignment, consistent spacing.
Content population — 32 peptides
Batch-created all peptide data files across 8 categories. Every peptide includes mechanism of action, research summary, citations with DOIs, protocols, side effects, storage info, related peptides, and FAQ sections.
Full site architecture
Hub & spoke architecture: 8 category pages, dynamic peptide pages, search, sitemap, robots.txt. JSON-LD schema on every page (MedicalWebPage, FAQPage, CollectionPage, BreadcrumbList). Dark/light mode.
Initial build
Created peptides-guide.com from scratch. Next.js 15, Tailwind CSS, Helvetica design system. Apple-inspired typography. llms.txt for AI agents. AI crawler access configured. 4 seed peptides (BPC-157, Semaglutide, GHK-Cu, Semax). Deployed to Railway + GitHub.
Entire site built in a single Claude Code session.
