What is GHRP-6?

What the compound is

GHRP-6 is a short synthetic peptide grouped under the label growth hormone secretagogue. That label describes the class a compound is sorted into, not a demonstrated effect in any particular person. This page does not assess whether GHRP-6 does anything useful, and it has no medical review behind it.

It is supplied as a lyophilized powder, freeze dried into a solid cake or film inside a sealed vial. Powder has no concentration. It has only a mass, printed on the label as 5 mg or 10 mg. A concentration exists once you add liquid, and it is entirely a consequence of how much liquid you add.

That is why a page like this exists. The mass is fixed by the seller. The volume is chosen by whoever reconstitutes the vial. Two people holding identical 10 mg vials can end up with solutions differing by a factor of three, purely from that choice.

Regulatory status

GHRP-6 is not approved by any regulator for human use. There is no approved label, no approved indication, and no regulator-reviewed document stating what amount is appropriate, for whom, or under what monitoring.

The consequence is that nothing about how the material is sold carries official meaning. Vial sizes of 5 mg and 10 mg are packaging conventions from suppliers, not dose recommendations. The amounts of 0.1 mg, 0.2 mg, and 0.3 mg that appear in listings are figures repeated by sellers. Their presence in the market is not evidence that they are correct or safe.

We cannot tell you what to take, what to expect, or whether any of this is safe. Those are clinical questions and this site does not answer them.

Reading the concentration table

The table shows what each vial size becomes at each of the three water volumes commonly used. Three things in it are worth pulling out.

First, the relationship is purely inverse. Hold the vial constant and double the water, and the concentration halves. A 5 mg vial goes from 5 mg/mL in 1 mL to 2.5 mg/mL in 2 mL. Nothing about the peptide changes. The same total mass is spread through more liquid.

Second, two different setups can land on the same number. A 5 mg vial in 1 mL and a 10 mg vial in 2 mL both give 5 mg/mL. The solutions measure identically, but the larger vial holds twice the total mass, so it contains twice as many equally sized withdrawals. Concentration and total contents are separate facts and are easy to confuse.

Third, the 3 mL rows give values that are not round: 1.67 mg/mL and 3.33 mg/mL. Awkward concentrations are not wrong, but they make every later volume calculation less clean and more prone to slips. Choosing a water volume that divides evenly into the vial mass is the easiest way to reduce measuring error.

What is not known, and what the listings do not tell you

We hold no reliable human pharmacokinetic data for GHRP-6. This site makes no claim about its half life, how quickly it clears, whether it accumulates with repeated use, or how long anything lasts. Timing, frequency, and spacing all depend on pharmacokinetic data, and without it there is no arithmetic to perform. Side effects, interactions, and contraindications are outside what this page covers, for the same reason.

Everything here is concentration and volume, which are properties of the vial and the water, not of the body. Listings quote amounts in milligrams. A syringe measures volume. Converting between the two requires the concentration you set when you chose the water volume, so the same quoted milligram figure corresponds to a different volume in every row of the table.

The error this produces is predictable. Someone reads a volume another person used, applies it to a vial reconstituted differently, and is off by whatever ratio separates the two concentrations. Work from your own vial mass and your own water volume, and write both on the vial. After the water goes in, there is no way to look at the liquid and tell what it is.

What we do not know

We hold no reliable human pharmacokinetic data for GHRP-6, so this site makes no claims about its half life, how long it takes to clear, or how it accumulates. The arithmetic below concerns concentration and volume only.

This page answers arithmetic and handling questions. It does not tell you what dose to take, what to expect, or whether anything is appropriate for you, and there is no medical review behind it.

Common questions

How much bacteriostatic water should I add to a GHRP-6 vial?

There is no correct answer, because the volume is a handling choice rather than a property of the compound. Volumes of 1 mL, 2 mL, and 3 mL are all in common use. The table shows what each choice produces, and picking one that divides evenly into the vial mass keeps later arithmetic simple.

Is a 10 mg vial twice as strong as a 5 mg vial?

Not necessarily. Strength means concentration, and concentration depends on the water. A 10 mg vial in 2 mL gives 5 mg/mL, the same as a 5 mg vial in 1 mL. The larger vial holds twice the total mass, so it lasts longer at a given withdrawal size, but the solution itself is identical.

What is the half life of GHRP-6?

We do not publish one. There is no reliable human pharmacokinetic data for this compound that we are willing to stand behind, so we make no claim about half life, clearance, or accumulation. Figures you find elsewhere may exist, but we cannot verify them.

Is GHRP-6 legal or approved?

It is not approved by any regulator for human use. Legality of possession and sale varies by jurisdiction and is a separate question from approval. Material sold for research use carries no regulator-reviewed dosing information.

What dose of GHRP-6 should I use?

This page cannot answer that. It has no medical review and does not give dosing advice. The amounts of 0.1 mg, 0.2 mg, and 0.3 mg listed here are figures observed in supplier listings, recorded because they affect the arithmetic, not because they are recommended.
