Four rules, in this order

  1. 1

    Match the goal

    Every peptide record lists the goals it has been studied for, most relevant first. The finder keeps the ones that match your goal, including those where it is a side interest.

  2. 2

    Apply your evidence bar

    "Approved only" keeps molecules sold as an approved medicine somewhere. "Human evidence" adds anything tested in people. "Include animal-only" adds the rest.

  3. 3

    Put approved medicines first

    Approved products always rank above unapproved ones, even when the unapproved one has a bigger trial. An approved product has passed manufacturing inspection and has a label with known side effects.

  4. 4

    Then rank on evidence

    Within each group, stronger evidence grade comes first, then peptides where your goal is the main research focus, then the number of human studies.

Frequently asked questions
What is the best peptide for weight loss?
The peptides with the largest human trials for weight loss are the approved GLP-1 drugs: semaglutide (Wegovy) and tirzepatide (Zepbound). In their main trials, average weight loss was about 15% of body weight on semaglutide over 68 weeks and about 21% on the highest tirzepatide dose over 72 weeks. Retatrutide has larger losses in trials but is not approved. A clinician can tell you whether any of them suits you.
Why does the finder put approved drugs first even when they are not approved for my goal?
Because an approved product is made to a known standard and its side effects are documented on a label. That is a different level of certainty than a research chemical of unknown purity. Each result says what the approval is for, so you can see when it is a different condition.
What does "research chemical" mean?
It means the peptide is sold labeled "for research use only, not for human consumption". It has not been approved for human use anywhere, and nothing checks that the vial contains what the label says. Many of the most discussed peptides, including BPC-157 and TB-500, are only available this way in the US.
Is a peptide with animal data only worth anything?
It shows a mechanism worth testing. It does not show that the peptide works or is safe in people. Most results in rodents fail to repeat in human trials, which is why the finder hides animal-only peptides unless you ask for them.
Does the finder recommend a peptide or a dose?
No. It sorts the published research so you can see what has been tested and how well. It never suggests a dose. Treatment decisions belong with a clinician who knows your history.
