How to Store Tesamorelin: Temperature, Shelf Life & Handling
Storage requirements for Tesamorelin follow from what the molecule actually is — full-length 44-residue ghrh analogue with trans-3-hexenoic acid modification. The conditions below reflect that chemistry rather than generic peptide guidance.
In plain English
Freezer for the powder, fridge once mixed, two to three weeks of use. Do not freeze mixed solution. Long chains have less margin than short ones, so keep time at room temperature to a minimum.
What Tesamorelin actually is
Tesamorelin keeps the body's own growth hormone-releasing signal completely intact — all forty-four amino acids — and adds one small chemical cap to the end. That cap exists for a single reason: an enzyme would otherwise destroy the natural molecule within minutes, and the cap blocks it from reaching its cutting point.

Storage conditions for Tesamorelin
Why these conditions, specifically
Storage requirements for Tesamorelin are set by its degradation chemistry rather than by a general rule for research peptides.
The main route to be aware of: aggregation at air–liquid interfaces from agitation — the practical failure mode for longer chains.
All 4 degradation routes for TesamorelinFreeze–thaw
Do not freeze reconstituted material. At this chain length, interfacial aggregation during freezing is a real risk.
What Tesamorelin is studied for
Full-length GHRH activity with DPP-4 resistance conferred by the N-terminal modification.
The most distinctive endpoint in its research literature.
Studied for effects on endogenous GH secretion patterns rather than direct GH substitution.
Investigated alongside body-composition endpoints in metabolic research.
Summarizes published preclinical literature. Provided for research reference only; not a claim of efficacy or a description of human use.
