Identity

What Tesamorelin is

Of everything on this list, tesamorelin comes with the most paperwork. It is a lab-made version of growth hormone-releasing hormone, or GHRH, carrying an extra chemical piece attached to the front that keeps it active longer once given. It is also the active ingredient in an FDA-approved drug, approved for one specific use in a defined group of adults.

Tesamorelin is a synthetic ghrh analog of 44 amino acid residues. SBz Industries sells it for laboratory research.

Research

What the research has looked at

In plain terms, with a link to every study. The most useful thing to notice is what each study was done in.

Tesamorelin has more published human research than most peptides on this list, including the large randomized trial behind its FDA approval and a separate trial that gave cognitive tests to older adults. Both used tesamorelin on its own, not combined with another peptide.

people2010

The large trial behind its FDA approval: 404 adults in a specific patient group, randomized to tesamorelin or a placebo for six months, with a smaller group followed for six more. The team used CT scans to measure fat stored around the internal organs.

Handling

Mixing and storage

Lyophilized: -20C, protected from light. Reconstituted: 2-8C.

Full handling guide
  1. 01

    Let it warm up

    Give the vial twenty minutes on the bench before opening it, so water does not condense onto the powder.

  2. 02

    Add bacteriostatic water

    Slowly, down the inside wall of the vial, never straight onto the powder.

  3. 03

    Let it dissolve

    Leave it alone until it clears. Do not shake it. Shaking damages the peptide.

  4. 04

    Refrigerate and use

    Once mixed, it breaks down much faster than the dry powder. Keep it cold and dark.

Questions

Common questions about Tesamorelin

What is Tesamorelin?

Of everything on this list, tesamorelin comes with the most paperwork. It is a lab-made version of growth hormone-releasing hormone, or GHRH, carrying an extra chemical piece attached to the front that keeps it active longer once given. It is also the active ingredient in an FDA-approved drug, approved for one specific use in a defined group of adults. SBz Industries sells it for laboratory research only.

Is tesamorelin FDA approved?

Yes, as the active ingredient in an approved drug for one specific use. It is not approved for anything else.

What else has tesamorelin been studied for?

One controlled trial gave memory and planning tests to older adults over 20 weeks. It is a single study, and its authors called for longer research.

How is Tesamorelin reconstituted?

Tesamorelin ships as a freeze-dried powder. Mix it with bacteriostatic water, added slowly down the inside wall of the vial, and let it dissolve without shaking. The researcher decides the working concentration, not us, and we publish no protocols.

How should Tesamorelin be stored?

Lyophilized: -20C, protected from light. Reconstituted: 2-8C. Vials ship in plain outer packaging with no product name on the outside.

Is Tesamorelin tested, and can I see the results?

Yes. An independent lab tests every compound: it confirms the compound is what the label says and measures purity by HPLC. The latest certificate is on the product page, and you can read it before you order.

Who is permitted to purchase Tesamorelin?

Researchers and institutions, 21 or over. By ordering you confirm the material is for laboratory research and will not be used in humans or animals.
