Tesamorelin
GHRH · GH / IGF-1
Tesamorelin is a stabilised GHRH analogue that stimulates pituitary GH release. Evidence and approval are indication-specific for HIV-associated lipodystrophy and do not support general weight-loss or anti-ageing use.

01 · Overview
What is Tesamorelin?
Tesamorelin is a stabilised GHRH analogue that stimulates pituitary GH release. Evidence and approval are indication-specific for HIV-associated lipodystrophy and do not support general weight-loss or anti-ageing use.
Research route, formulation and population determine what a result actually means.
02
GH / IGF-1
An increase in pituitary GH can raise downstream IGF-1 production; this is not direct IGF-1-receptor activation.

How to reconstitute Tesamorelin for laboratory research
A visual workflow for controlled laboratory reconstitution. Always follow the product label, COA and a validated protocol.
Clean
Disinfect the rubber closures of both vials and allow them to dry.
Measure diluent
Withdraw only the diluent validated for the specific compound.
Add slowly
Let the liquid run slowly down the inside wall of the vial.
Swirl gently
Do not shake; rotate gently until the material has dissolved.
Store per protocol
Follow the product label, COA and validated stability data.
Important checks before and after reconstitution
Check the product
First confirm that the product is a lyophilised vial. Prefilled pens and ready-to-use solutions do not require reconstitution. Check the label, COA and specified diluent.
Use clean, sterile technique
Wash your hands, clean the work surface and use new sterile equipment for every procedure. Clean both rubber closures with separate alcohol swabs and let them dry completely.
Concentration, not total amount
The volume of liquid added changes the concentration in mg per mL, but not the total amount of research compound in the vial. Use the calculator to check this in advance.
Inspect and label
Check for unexpected discoloration, cloudiness or visible particles. Record the compound, concentration and reconstitution date. Storage time and temperature are product-specific; a fixed 28-day rule does not apply to every compound.
General reconstitution volumes listed by the source
General examples, not a product-specific protocol. The chosen volume determines concentration; always check the label, COA and calculator.
| Vial strength | Commonly listed volume |

| 2 mg | 1–2 mL |
| 5 mg | 2–3 mL |
| 6 mg | 2–3 mL |
| 10 mg | 2–4 mL |

05 · Safety and limitations
Safety and limitations
Research route, formulation and population determine what a result actually means.
What is known
- Visible research claims use primary or official sources.
- The calculator is arithmetic and does not turn a study amount into medical advice.
- A registered medicine and a research vial are not automatically equivalent.
What remains uncertain
- Many products lack long-term safety data and independent replication.
- Animal and cell findings do not predict a safe human dose.
- Stability depends on formulation, pH, sterility, light, temperature and packaging.
