Free deep dives on the compounds longevity circles talk about. What each one does, what the studies actually show, and how people use it, written for someone with no biology degree.
One tile per compound. The bar under each name is the human-evidence meter from that guide: one rung means lab-dish data, three means small human studies, five means an approved medicine. Every guide opens as a PDF in your browser.
How peptides work, how to read a study, how to vet a vendor before you spend a dollar, and the questions to ask before any compound on this page.
Open the Starter GuideSymbols are ours, not chemistry's. The meter reading is taken from each guide's evidence page, which also explains what the rung means for that compound.
The same seven pages in the same order, so once you have read one you know where everything is in the next.
A plain summary, an analogy, and who it is and is not for.
The mechanism in three steps and a comparison table.
Key results, what is known, what is still open, and an honest take.
Starter, standard and full courses with what each one needs.
Do not use, be careful, stop if, and what to check first.
Where I order, or alternatives when it is not stocked.
A printable log for the course.
Most of what is written about peptides is either a sales page or a warning label, and neither helps you decide. These guides try to do what a good clinician does for a friend: explain the mechanism in plain words, say what the studies actually showed, be clear when the human evidence is thin, and still describe what a sensible course looks like if you choose to go ahead.
Nothing here is medical advice. It is the research, translated, with the analogies that make it stick and the numbers that let you check it.
Every guide grades the human evidence on the five-rung meter before it says a word about how much to take.
Analogies carry the mechanism; the actual figures from the studies stay in, so a claim can be checked rather than trusted.
When a vendor does not stock a compound, or the trials missed, the guide says so and shows the alternative.
Limitless Life, the one vendor I have vetted and use myself. Third-party tested; prices show once you create a free account on their site. The site header reads Limitless Biotech, same store.
Affiliate links, at no extra cost to you. Using them keeps these guides free. Educational content about published research, not medical advice; talk to your doctor before any health decision.
