GHRP-6 was one of the first ghrelin-receptor hexapeptides to be characterised, and it remains one of the most frequently referenced GHRPs in India's peptide-research community. Here's what it is, where it turns up in the literature, what it costs, and how to source a batch with a real Certificate of Analysis.
- GHRP-6 is a synthetic hexapeptide and ghrelin-receptor (GHS-R) agonist — one of the earliest compounds in the GHRP family.
- At OMNIPOTENT it's HPLC ≥99% pure with a batch COA, from ₹4,699 for the 5 mg vial.
- Larger 10 mg vials and BAC-water bundles are available, up to ₹9,199.
What is GHRP-6?
GHRP-6 (Growth-Hormone-Releasing Peptide-6) is a synthetic hexapeptide — a chain of six amino acids — first developed decades ago as one of the original ghrelin-mimetic research tools. It binds the growth-hormone secretagogue receptor (GHS-R1a), the same receptor that the endogenous hormone ghrelin acts on, which is why the GHRP family is grouped together as "ghrelin-receptor agonists" in the literature. Its small size relative to full-length growth-hormone-releasing hormone analogues is part of what made it attractive to early researchers: a short, synthetically accessible sequence that reliably engaged the target receptor in laboratory assays, which is why it became one of the reference tools for the whole GHRP class that followed it.
Where GHRP-6 appears in the research literature
GHRP-6 shows up most often in growth-hormone secretagogue research and in studies mapping the ghrelin-receptor pathway. Because it was among the first compounds in its class, it's frequently used as a reference ligand in receptor-binding and pharmacology papers — new secretagogues are routinely benchmarked against it. It's also referenced in appetite-signalling literature, since the GHS-R pathway that GHRP-6 engages is tied to orexigenic (appetite-related) circuits in the hypothalamus, making it a useful tool compound for researchers studying that axis specifically, separate from growth-hormone release itself.
Why researchers still reference GHRP-6
Despite being one of the older compounds in the secretagogue family, GHRP-6 hasn't disappeared from the literature — it remains a common positive control in assays that need a well-characterised GHS-R agonist with a long publication history behind it. Because so many papers over the decades have already documented its receptor-binding behaviour, using it as a comparator gives a study something to calibrate against, rather than introducing an unfamiliar variable. That's a big part of why legacy compounds like GHRP-6 continue to sit alongside newer, more selective secretagogues on research-supplier catalogues instead of being phased out.
Storage & stability considerations
Lyophilised GHRP-6 is relatively stable when kept sealed, cold and away from light, which is the standard storage condition researchers use for peptide reference materials before reconstitution. Once reconstituted in bacteriostatic water, the working solution should be refrigerated and used within the handling window typical for short peptides, since repeated freeze-thaw cycles and prolonged room-temperature exposure are the two most common causes of peptide degradation reported in lab settings. Keeping a reconstituted vial's handling log — date of reconstitution, storage temperature, number of draws — is good research practice for any peptide, GHRP-6 included.
GHRP-6 vs newer secretagogues like Ipamorelin
GHRP-6 is a first-generation, broader-spectrum GHS-R agonist. Later compounds such as Ipamorelin were developed specifically to improve on that profile — the literature describes Ipamorelin as more selective at the GHS-R, with less of the secondary receptor activity associated with earlier GHRPs. That contrast is exactly why comparative-pharmacology labs tend to stock both: GHRP-6 as the historical reference compound, Ipamorelin as the selective counterpart. We cover that comparison in more depth in our Ipamorelin research guide, and the classic GHRH + GHRP research pairing in our CJC-1295 + Ipamorelin guide.
GHRP-6 price and sizes in India
GHRP-6 pricing in India varies a fair amount between sellers, largely because of differences in purity testing and whether a real batch-specific COA is actually provided rather than a generic template. At OMNIPOTENT, GHRP-6 is available in four configurations sized for different research scales — a 5 mg vial for smaller pilot work, and a 10 mg vial for labs running larger comparative studies — all HPLC ≥99% with a Certificate of Analysis:
| 5 mg vial | ₹4,699 |
| 5 mg vial + 10ml BAC water | ₹5,699 |
| 10 mg vial | ₹8,199 |
| 10 mg vial + 10ml BAC water | ₹9,199 |
The BAC-water bundles are a convenience option for researchers who don't already keep bacteriostatic water on hand for reconstitution. Which size makes sense depends on the scope of the study: a 5 mg vial is usually enough for a short pilot run or a single comparative assay, while the 10 mg vial suits labs running a longer series of trials where restocking mid-study would be inconvenient. Ordering the BAC-water bundle up front also means there's no delay between the vial arriving and reconstitution being possible, which matters if a protocol is time-sensitive.
Reconstitution & storage
GHRP-6 ships as a lyophilised (freeze-dried) powder. For laboratory handling it's reconstituted with bacteriostatic water and kept refrigerated once in solution, with the lyophilised vial itself stored cold and protected from light before reconstitution. Our step-by-step reconstitution guide walks through the process and shelf-life considerations in detail.
Quality, purity & sourcing in India
Every GHRP-6 batch at OMNIPOTENT is HPLC-tested to ≥99% purity, with the Certificate of Analysis for that specific batch supplied alongside the order. Mass-spec identity confirmation is available on request for researchers who want a second line of verification. If you're new to reading these documents, our COA verification guide explains what each field on the certificate means and what to check before you buy. Sourcing matters more than most first-time buyers expect: two vials labelled identically can differ substantially in actual purity if the supplier isn't running independent HPLC testing on every batch rather than relying on a manufacturer's self-reported certificate. Orders ship pan-India with 3-day delivery, and our coaches are available free of charge to walk through reconstitution, storage and handling after checkout — the same support is available whether you're ordering GHRP-6 for the first time or restocking an ongoing study.
