Full disclaimerAbout Peptide Schedule
Peptide Schedule is the most complete free peptide resource online. 150+ peptides with dosage calculators, a protocol planner and tracker, calendar sync, community protocols, interaction checking, and science-based molecular icons. No paywalls. No sign-up required for most tools.
Good peptide info shouldn't be scattered across Reddit threads, paywalled sites, and sketchy PDFs. Most people starting out just want answers: "How much do I take? How do I mix it? When do I inject?" That's what this was built for.
Why We Exist
The peptide space has a serious information problem. Conflicting dosing advice across forums. Vendors making promises that published research doesn't support. People injecting peptides sourced from grey-market suppliers with no purity testing, some of which have been found to contain heavy metals, bacterial endotoxins, or the wrong compound entirely.
And an entire layer of quick-money operators white-labeling whatever they can source from Chinese manufacturers, slapping a brand on it, and selling it as "pharmaceutical grade" with no third-party testing to back the claim.
The data problem runs deeper. PubMed has almost nothing on most compounds. BPC-157 has 165,000 monthly Google searches but only 3 published human studies. 38% of popular peptides in our database carry a Grade C safety rating, meaning limited human safety data. The real dosing knowledge lives scattered across Reddit threads from years ago, YouTube comments, and Telegram groups nobody can search.
The founder's own experience trying to research BPC-157 made the gap obvious: there was no single place that combined published research with real community experience, verified the dosing numbers, and was honest about what the science does and doesn't support. That's what Peptide Schedule exists to fix.
Published research from PubMed, FDA, and clinical trials on one side. Structured community data from tens of thousands of real users on the other. Every dosing number is cross-referenced against at least two independent sources. Every page labels whether a claim comes from an FDA label, a clinical trial, or community consensus.
The longer-term goal is bigger. If people are already using peptides, give them proper tools to log protocols and track outcomes. Structured, anonymized data from real users could advance the research that formal institutions haven't funded yet.
How We Work
PubMed, FDA labels, clinical trials, and established peptide databases. Published data comes first.
Real-world experience from tens of thousands of user reports, protocol logs, and community discussions fills the gaps clinical data can't.
Every dosing number gets checked against at least 2 independent sources. Conflicts over 2x get flagged for manual review.
Multi-step pipeline: research, cross-referencing, QA validation, final review. Every page shows when it was last verified.

What We Don't Do
- We don't sell peptides. Not a vendor, pharmacy, or marketplace.
- We don't give medical advice. Our tools are references, not prescriptions.
- We don't diagnose or recommend treatments. Talk to your healthcare provider.
- We don't recommend vendors or sourcing. That's your call.
