What does the research on GHRP-6 investigate?
GHRP-6 is a hexapeptide and it is the tryptophan content that makes it distinct from its close relatives in this catalogue: the sequence carries two, one of them in the D configuration. Tryptophan is the most readily oxidised of the standard amino acids, so two of them means twice the exposure, and on a purity trace this compound accumulates oxidative products more visibly than the single-tryptophan peptides do. The chain also ends in an amide and includes D-configured residues, which is what makes a six-residue peptide survive long enough to be worth studying. Its length means identity confirmation is unambiguous and the whole mass is small enough that a single modification is a large fractional change - useful when reading a certificate, because an oxidised fraction that would be a rounding error on a kilodalton peptide is clearly visible here. Published in-vitro work uses the sequence in receptor-binding studies. This page describes the material and its documentation only.
Who can buy GHRP-6?
GHRP-6 is supplied strictly as a research chemical for in-vitro laboratory research. Products are sold exclusively to qualified researchers and licensed laboratories.
At checkout the buyer confirms that they are 18 or over, are buying in the course of research, and are responsible for handling, storing and disposing of the material in line with their laboratory's procedures. GHRP-6 is not for human or veterinary use.
We only answer questions about specifications, documentation and orders.
How are identity and quality assured?
Each released lot is tested and the result is published, rather than the material being described as high purity on the strength of a supplier's word. Purity is measured by reversed-phase HPLC at an independent laboratory. The laboratory used for every lot published so far is Janoshik Analytical, in the Czech Republic, and the result is stated alongside the measured content against label so the two can be read together.
The report carries the lot number printed on the vial, which is the part that matters. A certificate showing a result without a lot number cannot be tied to the vial in front of you, and a certificate for a different lot tells you nothing about yours. Matching the printed number on the label to the number on the report is a five second check and it is the whole point of publishing both.
Identity confirmation by mass spectrometry is a separate test and is ordered as an add-on, so the figures published here come from RP-HPLC purity testing unless a report says otherwise. Where no report is published for a listing yet, the documentation held for the lot being shipped can be requested before you order. We would rather send you what exists than let you assume a certificate is available when it is not.
Synthesis and supply
Peptide material is built by solid-phase synthesis, purified by preparative HPLC, then lyophilised. Lyophilisation freezes the solution and removes the solvent under vacuum, which is why the vial arrives holding a cake or powder rather than a liquid and why a solvent has to be added before the material can be worked with. Removing water also removes the main route by which a peptide degrades in storage, which is the reason the format is used.
Sequence length and modification are what make batches differ in difficulty. Every coupling step is an opportunity for a truncated or deleted by-product, and a heavily modified or long chain presents more of them, which is why the purity trace rather than the headline figure is what a certificate is read for. Vials are filled and labelled with the lot number, and the lot number is what the report and the verification lookup resolve against.

Frequently asked questions
What separates GHRP-6 from GHRP-2 structurally?
The first three residues. GHRP-6 opens His-D-Trp-Ala; GHRP-2 opens D-Ala-D-2-Nal-Ala, swapping the D-tryptophan for a synthetic naphthylalanine. Both close D-Phe-Lys-NH₂ and both are amidated hexapeptides, but they are separate compounds, 56 g/mol apart and holding their own registry identities.
Does the histidine affect handling?
Its imidazole side chain has a pKa near neutral, so the net charge on the peptide shifts across the physiological pH range in a way the other secretagogues here do not. That matters for ion-exchange chromatography and for buffer selection during analysis.
Is "growth hormone releasing peptide" a description of a use?
No — it is a historical class name from the pharmacology literature, applied to a family of synthetic secretagogues characterised in cell and animal models. It describes where the compound sits in a research taxonomy. Index Peptides supplies GHRP-6 for laboratory research only and cannot advise on any application beyond that.
Is GHRP-6 supplied for human or veterinary use?
No. GHRP-6 is supplied as a lyophilised powder in a sealed vial and is supplied strictly as a research chemical for in-vitro laboratory research. Products are sold exclusively to qualified researchers and licensed laboratories, and buyers confirm they are 18 or over and purchasing in the course of research. We only answer questions about specifications, documentation and orders.
How is the purity figure measured, and what does it actually tell me?
Purity is measured by reversed-phase HPLC at an independent laboratory, and the result is published with the method conditions rather than as a bare percentage. The figure is the proportion of the UV-absorbing material in the chromatogram that elutes as the target peak. It describes the sample as analysed; it is not a statement about what the material is for. A high figure alongside a clean chromatogram is the useful combination, which is why the report is worth reading rather than the headline number alone.
What documentation comes with a batch?
Each released lot carries a number printed on the vial label and a report stating purity by RP-HPLC, measured content against label, and the testing laboratory. Reports published so far are listed on this page and collected on the certificate hub, and each carries a lot number that can be checked against the vial in front of you. Where a report is not yet published for a listing, ask before ordering and we will send the documentation that exists for the lot being shipped.
How should GHRP-6 be stored?
In the form supplied, as a lyophilised powder, the material is stable kept cold, dry and dark. For powder, that means a freezer at around minus 20 degrees Celsius, desiccated, with the vial sealed and shielded from light, which is how it should stay until you are ready to work with it. Bringing a vial to room temperature before opening avoids condensation on the contents. Once in solution the material is less stable than the powder and should be kept cold and used within a short working window. Choosing a solvent and storage conditions for your own work is your call, not ours.
Do I need bacteriostatic water to prepare it?
A lyophilised powder needs a solvent added before it can be worked with. Bacteriostatic water, which is water with 0.9% benzyl alcohol, is the common choice because the preservative extends the working life of the solution once the vial has been opened, and we supply it in 3ml and 10ml vials. It is not the only option: where a method cannot tolerate benzyl alcohol, use the solvent the method specifies. The choice affects the sample, so it belongs to the researcher.
How and when is an order shipped?
Orders are dispatched from the United Kingdom. An order placed before 4pm on a working day is collected the same day; weekends and bank holidays roll forward to the next working day. Delivery is tracked, and shipping is free on UK orders over 30 pounds, with tracked 48 hour service at 3.65 pounds below that. Tracking is sent when the parcel is collected, so the first scan is usually visible the same evening.
Why does GHRP-6 oxidise more readily than similar peptides?
It contains two tryptophan residues, and tryptophan oxidises more readily than any other standard amino acid. Two susceptible sites rather than one means more opportunities for the reaction, and it is the most likely change to show up when a sample has been stored or handled poorly. Oxidation adds sixteen daltons per residue affected, so the products are close in mass to the parent and appear as neighbouring peaks rather than as a distant impurity.
How does GHRP-6 differ from GHRP-2?
They are different sequences with different residue compositions and different masses, 873.0 g/mol against 818.0 g/mol, and they are not interchangeable analytically. GHRP-6 carries two tryptophans while GHRP-2 carries a 2-naphthylalanine, which means their oxidation behaviour, their hydrophobicity and their retention on a column all differ. Sharing a research area in the literature is not the same as being the same molecule.
What is the significance of the C-terminal amide?
It removes the free acid terminus that enzymes would otherwise attack, which is part of why a chain this short is stable enough to work with. It also changes the molecule's charge, since the amide carries no negative charge where a free acid would, and that shifts retention on a reversed-phase method. A batch lacking the amide is chemically a different compound with a measurably different mass.
What should be checked on a certificate for this peptide?
The purity trace, read with the tryptophan in mind - look for closely spaced peaks that would indicate oxidation rather than assuming any second peak is unreacted starting material. Confirm the measured content against label, and match the lot number to the vial. At this molecular weight the mass figure alone is a strong identity check, since there is little room for a hidden structural difference.
