Guides

Background reading to help you make sense of any peptide page. The badge definitions live on the methods page.

• What the badges mean

  The difference between an approved medicine and a good result in mice, and why that gap matters more than how big the result was.

• Why animal results often do not carry over

  A tendon healing in a rat is not the same as a tendon healing in a person. Here is where the jump usually breaks down.

• Trial stages, plainly

  Phase 1 through 4, what each stage can actually tell you, and why a finished phase 2 does not prove something works.

• Lab test results: what they prove

  What an outside lab report covers, what it leaves out, and how to check that the batch number matches the paperwork.

• How long a peptide lasts in the body

  What half-life means, why some versions last much longer, and how not to read too much into the numbers.

• When all the research comes from one lab

  If every study traces back to the same research group, nobody has checked the work yet.
