How we build each peptide's range

Two kinds of numbers, kept apart: what people commonly use, and what studies gave. Here is where each comes from.

1. Common use ranges

For each peptide we look for the amounts people actually use, in this order:

  • The drug label, where the peptide is an approved medicine somewhere, or the dose steps from its main trials.
  • Published clinic and pharmacy protocols.
  • Widely used guides, only where several agree.

Every tier names its sources. If no source gives a number, the tier is left out. We do not fill gaps with a guess. Each page also says how well the sources agree, and when most of them come from businesses that sell the peptide.

2. Syringe units and vial math

Units assume a standard U-100 insulin syringe, where 100 units is 1 mL. Each page states the vial size and the amount of water the units are based on. A different vial or water amount changes every unit number. "Vial lasts" is the vial size divided by the amount used, and does not count waste.

3. Half-life

Half-life is how long it takes for half of a dose to leave the blood. We take it from the drug label first, then human studies, then animal studies, and say which. Where no study has measured it, the page says so.

4. The science

Under every range sit the published studies. Each amount is read from the study's own abstract, or its open full text, and kept in the units the study used. If the study does not state an amount, the row says Not stated in the abstract. Human and animal results are kept apart and never blended.

Most common-use amounts have never been tested in a study. The study section shows exactly how much research sits behind each peptide, and the proof grade sums it up.
