Reading a dose protocol without misreading it
Where the numbers on a compound page come from, what a range is telling you, and the unit slips that turn a protocol into a tenfold error.
Every dose on this site carries a label saying where it came from: a trial protocol, a review, or documented community practice. Those are three very different kinds of number, and the label is the most important thing on the row.
This is about reading them safely, not about choosing one. We describe what sources report and we do not recommend doses. The calculator only ever works on numbers you type in yourself.
What the source label means
A trial protocol is a dose given to selected participants under supervision. It was usually reached by titration, and it is usually reported as the maintenance dose, not the starting one. This is the strongest kind of number on the site, and it still describes a population rather than a person.
A review reports what a body of literature describes, which may quietly average protocols that had little in common.
Community practice is what people report doing. We include it because leaving it out does not stop anyone doing it. We label it because setting it next to a trial figure unlabelled would give it a standing it has not earned.
Reading the numbers
Check the unit before anything else
Micrograms and milligrams are a thousand apart, and both appear here because both appear in the sources. IU is not a unit of mass at all, and there is no general conversion to one.
Read a range as a range
Where a source gives a range, we print the range instead of picking a number out of it. The midpoint is not a recommendation. Neither is the top.
Separate dose from frequency
Two milligrams weekly and two milligrams daily are not the same protocol. Copying a dose without its frequency is one of the easiest bad mistakes to make here.
Check whether it is a starting or maintenance dose
For anything titrated, the number being quoted is usually where the protocol ended up months later.
Do the arithmetic against your own vial
A protocol is written in milligrams. A syringe is marked in units, a different quantity entirely. What you draw depends on how much water went into your vial, and that was your decision, not the protocol's.
The mistakes that cost the most
Carrying a dose between compounds
Dose scales here differ by orders of magnitude. BPC-157 is dosed in micrograms, TB-500 in milligrams, and the two are commonly run in the same week.
Reading IU as milligrams
There is no general conversion between them. Growth hormone is dosed in IU; almost nothing else on this site is.
Treating a blend like a single compound
One vial, a fixed ratio: dose by one component and you have set the dose of everything else in it.
Checking the result against the syringe in your hand
If the answer does not land on a printed line of the barrel in your hand, the water volume was the wrong pick.
