HOW TO READ
PEPTIDE EVIDENCE.

Not all evidence is equal.

When you read about a peptide online, the writer almost never tells you what the claim is actually based on. “Reduces inflammation” could mean a drug that went through years of human clinical trials before regulators approved it — or it could mean someone gave a single rat a sore knee and watched the swelling go down by 14%.

Both technically “reduce inflammation.” Only one is something you'd bet your health on.

BadgerSkope gives every compound a single letter grade — A through F — so you can see at a glance what level of proof the claim is built on. The next section explains exactly what each letter means.

Five tiers. One scale.

Every compound on BadgerSkope gets a grade from A to F. Tier A comes in two flavors — the “FDA approved” flavor and the “not yet approved, but the human trial data is very strong” flavor — but both earn the same A. Here's what each grade actually means.

Patterns that should make you skeptical.

When you're reading about peptides online, watch out for these. Any one of them is a reason to stop and check the source.

• “Clinically proven” with no link to a study. Proven by whom? In what trial? With how many people? If the claim doesn't link to a specific study, it's marketing copy.
• Online testimonials used as proof. Forum posts and customer reviews are not evidence. The people who didn't get results aren't usually posting; the people who did are loud.
• Studies paid for by the seller. If the company selling the product also funded or ran the study, that's a conflict of interest. It doesn't automatically mean the results are wrong, but it's a reason to look harder for independent research.
• Animal results presented as if they were human results. Roughly 90% of compounds that work in mice don't work in people. A mouse study is a starting point, not proof.
• “The mouse dose converts to X mg in humans.” That math is a rough estimate, not a prescription. Real human dosing only comes from real human trials.
• “No side effects” claims. Anything biologically active in your body has side effects. If a seller claims their compound has zero downsides, they either haven't looked or aren't telling you.
• Mixing approved-drug data with unapproved knock-offs. The FDA approved Ozempic. It did not approve a random vial labeled “1G-SGT” from an unregulated compounder. The active ingredient may be the same; the purity, sterility, and dosing accuracy almost certainly aren't.

Six steps. Ten minutes.

You don't need a science degree to read peptide research with a critical eye. You need ten minutes and a healthy skepticism toward marketing.

1. Check our grade first. If the BadgerSkope file says “Animal Only,” you already know the claim hasn't been tested in humans.
2. Open the linked sources. Do they actually say what's being claimed? Read at least the abstract. You'd be surprised how often a citation doesn't support the claim it's attached to.
3. Look at how the study was designed. How many people? Was there a placebo group? How long did the study run? A 12-person, 4-week study tells you something very different from a 3,000-person, 2-year trial.
4. Check who paid for the study. Industry-funded research isn't automatically wrong, but independent replication carries more weight.
5. Search PubMed yourself. Go to pubmed.ncbi.nlm.nih.gov and type in the compound name. Skim a few abstracts. Takes five minutes.
6. One study is a signal, not proof. Science works by replication. One positive result is interesting; the same result coming from multiple independent labs is evidence. Look for consistency.

What this site is, and isn't.

BadgerSkope is a reference for understanding peptide research. It is not medical advice, prescribing guidance, or an endorsement of any product. Many compounds we cover are not FDA-approved for human use, and the legal status of any specific compound varies by country.

A few specific things worth being clear about:

• The grades are editorial judgments, not a validated instrument. The A–F scale is our reading of the evidence, not a peer-reviewed scoring system. We show our sources so you can disagree with the call — and we re-grade in public when a reader makes the case.
• Some files are thinly sourced. A compound with one citation is graded on one citation. The source list on every file is the honest picture of how much we had to work with — if it looks thin, it is thin, and the grade should be read that way.
• Summaries aren't instructions. When a file mentions a typical dose, a timing pattern, or a cycling protocol, that's a summary of what published studies (or drug labels, or animal research) describe. It is not us telling you what to do.
• “Stacking” notes are observations, not recommendations. When we note that two compounds are sometimes used together, we're describing what shows up in trials, on labels, or in vendor marketing — not suggesting you combine them.
• “Reported benefits” are claims, not promises. Each is tagged with how strong the underlying evidence is. None of them are guarantees of how a compound will work for any one person, especially when bought from a grey-market vendor.
• If you're considering anything as actual treatment, the right next step is a licensed clinician — not the badger. Controlled drugs and prescription-grade peptides legally require medical supervision in most places.

What “not medical advice” actually means.

Every page on BadgerSkope says “not medical advice.” That's not a legal disclaimer printed in small text; it's an honest description of what this site can and can't do.

Translating research into plain language is not the same as prescribing a treatment. A summary can tell you what the studies show. It cannot tell you what you should do given your health, your medications, and your tolerance for risk. That conversation belongs with a licensed professional.
