Peptides
One hundred compounds at the frontier, each graded on the human evidence that exists.

The foundation
Everything we publish rests on this.
Health is the most personal thing there is, and the search for answers about it tends to create more worry than it settles. The tabs multiply. The voices all seem to want something from you. We built the Ēnel libraries and atlases because we had lived that too many times, and because we came to believe no one should have to.

Where this began
The decision made at the point of exhaustion.
Looking for health answers is unlike shopping in any other category. Nearly every voice, especially the ones that top a search, belongs to someone with something to sell. That holds even for good companies. Some supplement makers test through independent labs and still lack the research to carry the claims on their own bottles. So we search wide, ten or fifteen tabs for one decision, and when we finally choose, we rarely do it because we found a satisfying answer. We do it because we ran out of strength to keep looking.
Almost everything else we buy passes through some kind of scrutiny. An ordinary device meets safety listings and testing. Independent reviewers examine it. Failures get remembered. Health has close to none of this. The trials that exist are small, run on people who do not represent a real cross-section, and their protocols forbid the way people actually live. Someone on antibiotics still has a glass of wine at a wedding, forgets a dose, takes the pill with breakfast when the label said empty stomach. Reality breaks the protocol every day, so the research, even when it is honest, sits at a distance from the lives it should inform.
It should trouble us that no one is protecting us here. We make our most personal decisions worn out, not satisfied. That is the problem these libraries were built to answer.
About the collection
The libraries and the atlases.
One is the ground. The other shows how that ground shifts when it crosses a border.
A library
A library holds what you would find if you spent hundreds of hours searching on your own: the whole internet's worth of looking, with the best of it gathered and sorted, and the wrong and misleading marked for what they are. The libraries cover fasting, circadian biology and sleep, probiotics, children's and mothers' health, women's health, the world's healing traditions, home health devices, supplements and peptides, and the hands-on therapies people have practiced as long as there has been medicine. They are built to be navigated, and they surface considerations you would never have thought to weigh.
An atlas
An atlas shows how the same fact changes shape as it crosses a border. The Regulatory Atlas follows eleven contested substances through ten jurisdictions and records, cited to the regulators themselves, how one molecule can be sold over the counter in one country, need a prescription in a second, and be banned in a third. Nothing about the molecule changes. What changes is the legal philosophy waiting to receive it.
Our standards
How the entries are written.
Sourcing matters more than anything else on the page. Thousands of citations lead to medical bodies, regulators, and the primary literature, rather than to anyone with something to sell. Where the best source was once a commercial page, we replaced it with the regulator or the trial itself. We do not call anyone out by name. But when something widely believed to work does not, we say so without hedging, and we show the evidence.
Grading with honesty
Settled anatomy and physiology carry the highest confidence. Interventions carry whatever confidence the trials have actually earned. When enthusiasm has run ahead of the data, the entry says so plainly.
Preserving the lineage
Practices and substances travel under many names across eras and regions. Every entry records what its subject has been called, because an older name is often the key that unlocks the older evidence.
A fair hearing
A centuries-old practice gets rigorous attention rather than reflexive dismissal. A newly fashionable compound gets scrutiny alongside curiosity. We decline the usual choice between credulity and contempt.

How to read it
Field Notes and the Constellation are views onto this.
The libraries and the atlases are the foundation. Field Notes are evidence-graded summaries of single compounds, drawn straight from that reference layer. The Constellation is a personal health map that plots your questions against the same source. The bedrock does not move. The product is how you look at it.
Field Notes and the Constellation are two views that read from the Libraries and the Regulatory Atlas, the cited reference layer.

A note from the founder
Why I built these.
I built these because I have lived this problem, for years, and in my own family. What I wanted and never found was a single place I could put my faith in. Not a feed, not a store, not another voice with something to sell. A reference that had already done the hundreds of hours of looking, sorted the best of the internet from the worst, and would tell me the truth even when the truth was that nobody really knows yet.
That is what these libraries and atlases are. They exist so you can widen your whole view of your health, whether you are trying to live longer, live better, or find your way back after illness or injury. We built them for you, and for ourselves, and for our families, in equal measure. My hope is a simple one: that these pages bring you comfort instead of worry, and give you, in the first tab you open, the answer you came for.
A single source of truth for your health.
