Never heard of any of this? Good — start clean.

Five short steps. No science background needed, nothing for sale at the end, and you can stop after any of them and still leave knowing more than most people who buy this stuff.

01

What these compounds actually are

This site covers 65 substances sold online as “research compounds.” Most are peptides: short chains of the same building blocks your body uses to make proteins, made in a lab. They usually ship as powder in a small glass vial, get mixed with sterile water, and are injected at home.

Two things make them different from anything at a pharmacy. They are not approved medicines, so nobody checked whether they work or are safe in the form being sold. And they are not supplements either — most are sold with a “not for human use” label that everyone involved understands to be a legal fiction. People take them anyway, for recovery, weight, sleep, skin, and aging. This site does not tell you to. It tells you what is actually known.

02

The one thing to understand about the dose numbers

Search any of these compounds and you will find confident dosing guides: “250 to 500 micrograms daily.” Here is the thing this site exists to say plainly: most of those numbers do not come from studies. The BPC-157 dose everyone repeats appears in no published study in any species. It is exactly one twentieth and one tenth of the 5 mg vial it ships in — the easiest marks to read on a syringe. The dose came from the packaging.

We traced this for all 65 compounds. For 26 of them, no published human dose exists to compare against at all. The whole comparison sits in one table, and it is not a protocol — it is the receipts.

03

How to read our pages

Every compound here has a card. Three fields carry the point: what circulates is the dose people actually use, reported because it happens, not because we endorse it. What was studied is what a published trial really gave people, with the source. The gap is the distance between those two, and it is the only judgement we print.

dot above the line: people take more than was ever studied

broken line: there is no studied dose to compare against at all

No stars, no scores, no red or green. A dot above a line is a fact, not a warning label — you bring the judgement.

Five words you'll see a lot

Peptide
A short chain of amino acids, the building blocks the body uses to make proteins. Most compounds covered here are peptides made in a lab.
Vial
The small glass bottle the powder ships in. The number on it (5 mg, 10 mg) is the total amount inside, and it quietly shapes the doses people take.
Reconstitution
Mixing the powder with sterile water so it can be measured and injected. Getting this arithmetic wrong hurts more people than the compounds do.
COA
Certificate of analysis: a lab report saying what is actually in the vial. The only evidence a label is telling the truth.
Half-life
How long a substance lasts in the body before half of it is gone. For many compounds here, nobody has ever measured it in a person.

Where to go from here

If you came about one compound, type its name into search — spelling barely matters — or browse the full reference. Weighing two options? Put them side by side. If you are going to mix a vial regardless of anything written here, use the calculator first, because the arithmetic mistakes are the ones that hurt people fastest. And if you want to know why you should believe any of this, how we read research and the corrections log are the receipts behind the receipts.
