Free six-part course for beginners
The Beginner’s Guide to Peptides
It picks your starting lesson.
Six short lessons, about twenty minutes, and you will be able to judge a peptide claim yourself.
What peptides actually are. How to tell a real finding from marketing copy. Who they are not for. And how to read a lab report before you spend anything. No doses, no protocols, no compound recommended to you.
What the course covers
The three questions everyone arrives with.
Two of them we answer properly. One of them we refuse, and the refusal is the point.
“Which peptide should I take?”
Covered in lesson 3We will not answer that, and you should distrust any site that does without knowing your history. What we do instead: show what people research for each goal, with the evidence state attached, so the judgement stays yours.
“Does it actually work?”
Covered in lesson 2For most compounds, nobody knows, because it has never been tested in a human being. That is a real answer, not a dodge. Lesson 2 teaches you to tell a finding from a claim in about three minutes.
“Is this for me?”
Covered in lesson 4That turns on your medications, your history and your age far more than on the compound. Lesson 4 names the groups these are not for without hedging, and the drug combinations with documented risk.
What this site will and won’t do.
Grade every claim A to X, and link the study it came from so you can read it yourself.
Say when there is no human data. Silence gets marked Grade D, not left blank.
Show the disagreements. Where trials conflict, you get an X and an explanation.
Do arithmetic on your numbers. The calculator converts what you enter; it never suggests what to enter.
Tell you which compound to take. That is a clinician’s job, with your chart in front of them.
Give you a dose or a protocol. Not in an article, not in a quiz, not in the calculator’s defaults.
Rank or score vendors. We show you how to read a certificate of analysis instead.
Promise anything is risk-free. No compound here is, and the ones with the least data are not the exception.
If you came here for a protocol, this is the wrong site. What you get instead is the ability to read the evidence behind any peptide claim you meet, here or on a forum or in a sales page, and work out how much of it is real.
Six lessons, from what even is a peptide to reading a lab report.
Each lesson stands alone, but they build. Lesson 2 is the one that changes how you read everything else.
1What peptides areShort chains of amino acids. A few are approved medicines; most of what is discussed online is not approved for human use.· The three groups: approved medicines, investigational compounds, and unapproved research material· What research use only actually means, and what it does not· Why what is in the vial varies so much between sellers
2Reading the evidenceMost peptide claims rest on animal studies. Here is the grading system we use, and how to tell data from marketing.· What grades A, B, C, D and X each mean in practice· Why most peptide claims sit at Grade D: animal or lab work only· Four questions that tell you whether a study means anything
3Goals and categoriesWhat people research for common goals, and how much is actually known about each. Categories, not recommendations.· What people research for metabolic, recovery, skin, growth-hormone and longevity goals· Which categories have human trial data behind them, and which have none· Why a category label hides enormous differences in evidence
4Is this for you?Who these compounds are not for, the medications that matter most, and why absence of a documented interaction is not reassurance.· Who these compounds are not for, without hedging· The medication combinations that carry documented risk· Why no known interaction is not the reassurance it sounds like
5Safety basicsSterile technique, storage and handling, injection-site basics, and the adverse-event signs that mean seek care now.· Sterile technique, and which habits actually reduce risk· How storage and degradation quietly change what is in your vial· The adverse-event signs that mean seek care now, not later
6Sourcing and COAsWhat a certificate of analysis shows, what it cannot show, and the red flags worth knowing before you spend anything.· What mass spec and HPLC each actually tell you· The four things a certificate of analysis cannot prove· Red flags on a lab report, and why we publish no vendor scoresThe evidence scale
Every claim on this site carries one of these five grades. Lesson 2 teaches you to apply them yourself, which is the part that transfers off this site.
Two tools, waiting for you.
The peptide library
Every compound, claim by claim, each one graded A to X with the study attached. Including the ones where the honest entry is no human data exists.
