Peptides, explained simply

New to peptides? Start here. In a few minutes you will know what they are, which ones people ask about most, how to read a lab report, and where the FDA fits in.

A real peptide, bead by bead: the 15 amino acids of BPC-157.

The basics

What peptides are

A peptide is a short chain of amino acids, the same small building blocks that make up every protein. Link a few dozen together and you have a peptide. Link hundreds and you have a protein.

  1. Step 1: Amino acids

    Amino acids are small molecules. There are 20 common kinds, and all living things build with the same set.

  2. Step 2: Linked into a chain

    Amino acids join end to end through a peptide bond. The order they sit in is called the sequence, and it is what makes each peptide its own molecule.

  3. Step 3: Peptides and proteins

    Peptides are short chains, usually from 2 to about 50 amino acids. Proteins are far longer, often hundreds, folded into a 3D shape.

  4. Step 4: Made, then freeze-dried

    Research peptides are built by machine one amino acid at a time, purified, then freeze-dried into a fine powder and sealed in a glass vial. That powder is what you see at the bottom of each vial.

Lab reports

How to read a lab report

A lab report is a record of what an independent lab measured in a sample. Six spots on the page tell you almost everything: the task number, the sample, the purity, the amount, the date, and how to check it with the lab yourself.

A real third-party lab report from Janoshik Analytical for a BPC-157 10 mg sample, task number 85186, showing 10.89 mg measured and 99.825% purity, analysis conducted 30 October 2025. The client and manufacturer fields read "Not shown".
Independent lab report Janoshik #85186 (BPC-157 10 mg). Full report on the BPC-157 page.
  1. 1. Task number

    Every report has its own number. This one is #85186. It is how the lab finds the report again.

  2. 2. Sample name and strength

    What was tested: BPC-157 from a 10 mg vial. It should match the product you are looking at.

  3. 3. Purity (HPLC)

    How much of the powder is the peptide itself. HPLC is the lab method that separates and measures it. Here it reads 99.825%.

  4. 4. Measured amount

    How much peptide the lab found in the vial: 10.89 mg, in a vial labelled 10 mg.

  5. 5. Test date

    When the analysis was done, here 30 October 2025. A clear date tells you when the sample was measured.

  6. 6. Check it with the lab

    Go to janoshik.com/verify and enter the unique key printed at the bottom. The lab's own site shows you its copy, so you can see it matches.

Check the lab

Look for a named, independent lab you can verify online. A report with no lab name cannot be checked.

Check the date

A clear test date tells you when the material was measured. Recent is better.

Match the product

The sample name and strength on the report should match the vial you are buying.

FDA approval

Why most peptides aren't FDA approved

Follow the money.

Two paths

  1. Patented drug
  2. Pharma pays for trials
  3. FDA approval
  4. Sold at prescription prices
  1. Most peptides
  2. Not patentable
  3. Nobody pays for trials
  4. No approval

The system isn't built for your health.

  • Pharma won't spend $1B testing something it can't own.
  • The companies being reviewed pay for most of the reviews.
  • Sick customers buy refills every month. Healthy people don't.

That's why we let the lab reports do the talking.

  • Sealed

    Every vial arrives sealed, as it left the maker.

  • Labeled

    The compound name and strength are printed on the vial.

  • Lab-tested

    Third-party lab reports you can check with the lab yourself.

  • Sold for research

    Offered as research compounds, for laboratory research.
