What this is
A stabilized synthetic analog of growth-hormone-releasing hormone (GHRH).
Growth-hormone-releasing hormone is a hypothalamic peptide that acts one level up the chain from growth hormone itself — it signals the pituitary, and the pituitary does the releasing. Native GHRH is short-lived in circulation, which makes it awkward to work with. The word "stabilized" in that first sentence is the whole engineering story: the molecule has been modified to resist the enzymatic breakdown that clears the native hormone quickly.
That puts Tesamorelin in the same functional family as two other compounds in this catalog, and knowing which is which saves a lot of confusion:
- Sermorelin — the first 29 amino acids of GHRH, the active fragment, unmodified.
- CJC-1295 W/DAC — a GHRH analog bound to a Drug Affinity Complex that extends its activity in circulation.
- Tesamorelin — a stabilized GHRH analog, this page.
All three act at the GHRH receptor. They differ in how long they persist and in how they were engineered to get there.
Research profile
Studied in growth-hormone-axis and metabolic research as a model for GHRH-receptor signaling and GH secretion.
The "axis" framing matters. Research using GHRH analogs is generally not about the analog — it is about the hypothalamic-pituitary signalling chain, using the analog as an upstream input to see what happens downstream. That is a different kind of question from research using growth hormone directly, which bypasses the pituitary entirely.
Because Tesamorelin persists longer than native GHRH, the published work also tends to touch sustained-signalling questions rather than acute-pulse ones. Research suggests that distinction — pulsatile versus sustained receptor engagement — is one of the more active open questions in the area.
Nothing here is a claim about outcomes. These are the questions the literature asks.

Lab testing and this lot's certificate
Every lot we sell goes to Vanguard Laboratory, an independent A2LA-accredited lab (A2LA certificate #6377.01.01) in Olympia, Washington, for chromatographic purity by HPLC-UV/VIS, quantity by assay, and endotoxin by LAL.
For lot VR06015260110 the certificate is not yet published. It is available on request — contact support and we will send what exists for this lot.
We are telling you this on the product page rather than burying it, because a supplier who only mentions certificates when they are flattering is not really running a certificate program. Our published certificates are all on the lab tests page, and the batch lookup there will tell you the status of any lot in seconds.

Handling and storage
Lyophilized. Reconstitute with bacteriostatic water; store at minus 20C.
Sealed powder at −20°C. Ambient shipping is fine for lyophilized material. Reconstituted solution is a working preparation, not long-term stock.
The reconstitution reference on this page converts diluent volume into resulting concentration. It is a reference for in-vitro laboratory handling only. Its outputs describe the physical properties of the reconstituted vial — concentration and mass drawn — and are not dosing guidance, administration instructions, or medical advice.
Bacteriostatic water sold separately.
Questions
Is there a published certificate for this lot?
Not currently. It is available on request. Published certificates live on the lab tests page.
How is Tesamorelin different from Sermorelin?
Sermorelin is the unmodified active fragment of GHRH — the first 29 amino acids. Tesamorelin is a stabilized analog engineered to resist the enzymatic breakdown that clears native GHRH quickly.
How is it different from CJC-1295 W/DAC?
Both are GHRH analogs with extended activity, but they get there differently: CJC-1295 W/DAC is bound to a Drug Affinity Complex, Tesamorelin is stabilized in the sequence itself.
Why is there no purity number on this page?
Because there is no certified number for this lot yet, and we will not print one we cannot document. When the certificate lands, the number goes on the page.
What is the difference between the 10mg and 20mg vials?
Mass. Same compound, same handling, separate lots.
