How to Store GHRP-6: Temperature, Shelf Life & Handling
Storage requirements for GHRP-6 follow from what the molecule actually is — synthetic hexapeptide, met-enkephalin analogue and ghrelin-receptor agonist. The conditions below reflect that chemistry rather than generic peptide guidance.
In plain English
Freezer, fridge once mixed, two to three weeks, and strictly dark. This one contains two copies of tryptophan — the most light-sensitive amino acid there is — so it has double the exposure of a typical molecule and visibly yellows as it degrades.
What GHRP-6 actually is
GHRP-6 is a six-amino-acid molecule from the 1980s that triggers growth hormone release. It has a genuinely remarkable history: it was built and shown to work years before anyone identified the receptor it acted on, and the hunt for that receptor eventually led researchers to discover ghrelin in 1999.

Storage conditions for GHRP-6
Why these conditions, specifically
The D-amino acids at positions 2 and 5 confer good resistance to enzymatic degradation, but offer no protection whatsoever against photo-oxidation. Enzymatic stability and chemical stability are separate properties and this compound illustrates the distinction well.
The main route to be aware of: tryptophan photo-oxidation at two independent positions — the defining instability of this molecule.

What GHRP-6 is studied for
Acts at GHS-R1a — the receptor whose search for an endogenous ligand led to ghrelin's discovery.
Strong GH-releasing activity in research models, historically the compound's defining property.
Ghrelin-receptor activity links it to appetite pathways in metabolic research models.
A landmark in reverse pharmacology: the synthetic ligand preceded knowledge of both receptor and natural ligand.
