What Is A Peptide Protocol?
A protocol is simply the plan for using a compound. It answers a few practical questions: how much you take, how often you take it, how long you stay on it, and whether you take a break afterwards. Nothing more complicated than that.
Research peptides do not come with a standard label, so the plan has to be written out clearly. A good protocol tells you the vial size you are starting from, how much bacteriostatic water to add, and the low, medium and high amounts people research.
This peptide dosing guide collects that plan for every compound in one place. Pick a peptide above, or use the search box and category chips to narrow the list.
What Is On Every Protocol Page?
- Vial size. The size of the vial the protocol is written for, in milligrams (or international units for a few compounds). It is the starting point for every calculation, because it sets how much compound you have before anything is added.
- Bacteriostatic water. How much water to add to reconstitute the powder so it can be drawn into a syringe. That figure decides your concentration — the amount of compound in every unit — so it is given plainly rather than left to guesswork.
- Low, medium and high dose. A range rather than a single number: a conservative low dose, a common medium dose, and a higher dose seen in research. Showing all three lets you see where a dose sits within what has actually been studied.
- How often and how long. How frequently the dose is repeated — daily, several times a week, or weekly — and how many weeks a typical course runs before it ends.
- Wash-out period. Some compounds are cycled, meaning a break follows a course before it is repeated. Where a wash-out period is part of the plan, the page says so, and how long it usually lasts.
- Strength of the evidence. How strong the underlying research is, with links to the studies behind it, so you can judge for yourself rather than take a number on trust.
These are research compounds, and most are not approved by the FDA for human use. The information here describes what has been studied, not a recommendation to use any compound, and it is not medical advice.
What Do People Ask About This Peptide Dosing Guide?
How do you dose peptides?
You start from the vial size, add a set amount of bacteriostatic water to reconstitute it, then draw the dose on an insulin syringe. Each protocol page here lists the vial size, the water to add and a low, medium and high dose, so you can see the full range at a glance.
Can you use reconstitution solution instead of bacteriostatic water?
Bacteriostatic water is the standard choice because the benzyl alcohol in it limits bacterial growth, so a vial keeps for weeks refrigerated. Sterile or plain water has no preservative and is meant for a single use. Where a protocol calls for bacteriostatic water, that is what the numbers on the page assume.
Is a GLP-1 a peptide?
Yes. GLP-1 receptor agonists such as semaglutide, tirzepatide and retatrutide are peptides, built from short chains of amino acids. They act on the GLP-1 pathway to influence appetite and blood sugar. On this site they sit in the main list alongside every other compound, not in a class of their own.
What is a wash-out period, and do all peptides need one?
A wash-out period is a planned break after a course, giving the body time before the next cycle. Not every peptide calls for one — some are run continuously, others are cycled. Where a wash-out is part of the plan, the protocol page states it and how long it usually lasts.
Why does every protocol show a low, medium and high dose instead of one number?
Because research uses a range, not a single figure. A low dose is conservative, a medium dose is the common middle ground, and a high dose sits at the upper end of what has been studied. Showing all three lets you see where any dose falls within the evidence rather than trusting one number.
How do I know which vial size to buy?
Match the vial size to the dose and frequency in the protocol. A larger vial lasts longer per reconstitution but must be used before it expires. The calculator on this site works out how many doses a given vial and water amount yield, so you can size a purchase to a full cycle.
How strong is the evidence behind these protocols?
It varies by compound. Some are backed by human trials, others only by animal or laboratory work. Each protocol page notes the strength of the evidence and links to the underlying studies, because these are research compounds and most are not approved by the FDA for human use.
Are any of these approved by the FDA?
A few, such as the GLP-1 drugs and teriparatide, are FDA-approved medicines used under prescription. Most compounds listed here are research peptides that are not approved for human use. Each page flags where a compound is approved, so the difference is never left unclear.
