Tesamorelin is unusual among research peptides: the molecule is widely studied in growth hormone–releasing hormone research, while tesamorelin is also the active ingredient in an FDA-approved prescription product for a specific medical indication.
For laboratories and professional B2B buyers, that makes one distinction especially important:
Research-grade Tesamorelin should never be evaluated by name alone. Identity, purity and batch documentation matter.
What Is Tesamorelin?
Tesamorelin (CAS 218949-48-5), also known as TH9507, is a synthetic analogue of human growth hormone–releasing hormone (GHRH).
It consists of a modified 44-amino-acid peptide sequence and is commonly studied in research involving:
- GHRH receptor signaling;
- growth hormone release pathways;
- GH/IGF-1 axis biology;
- endocrine signaling;
- metabolic research.
These areas have made Tesamorelin research peptide an important reference compound in growth-hormone-related laboratory research.
Research-Grade Tesamorelin Is Not the Same as an Approved Drug Product
Tesamorelin is also the active ingredient in an FDA-approved prescription medicine used for a specific indication in adults with HIV-associated lipodystrophy.
However, that approval applies to the finished, regulated pharmaceutical product — not automatically to third-party research materials containing the same peptide name.
Professional buyers should distinguish between:
FDA-approved pharmaceutical Tesamorelin products
and
Tesamorelin supplied as research-grade raw material or laboratory peptide.
The latter should be evaluated according to its own batch specifications, identity testing and analytical documentation.
What Do Tesamorelin Reviews Say?
Online experiences involving Tesamorelin are highly mixed.
Some users report perceived changes involving abdominal body composition, energy or sleep.
Others report:
- headaches;
- fatigue;
- water retention;
- joint discomfort;
- numbness or tingling;
- nausea;
- no noticeable benefit.
These online reports should not be interpreted as proof of safety or efficacy.
Different product sources, patient populations, other compounds and underlying health conditions can all affect reported experiences.
For laboratories, anecdotal reviews are therefore much less useful than verified analytical data.
Choosing a Tesamorelin Supplier: What Should B2B Buyers Verify?
1. HPLC Purity
A Tesamorelin HPLC purity result can help characterize relative peptide purity and impurity profiles.
A high percentage alone, however, does not prove molecular identity.
2. LC-MS or Other Identity Testing
Where available, Tesamorelin LC-MS identity provides additional evidence that the supplied material corresponds to the expected molecule.
3. Batch-Specific COA
A professional Tesamorelin Certificate of Analysis should correspond to the actual production lot.
Useful documentation may include:
- HPLC purity;
- identity testing;
- lot or batch number;
- molecular information;
- product specifications;
- SDS;
- storage requirements.
4. Content and Traceability
Some professional buyers also review net peptide content and lot traceability, especially when reproducibility between research batches is important.

Tesamorelin FAQ
What is the CAS number of Tesamorelin?
Tesamorelin is commonly listed under CAS 218949-48-5.
What type of peptide is Tesamorelin?
Tesamorelin is a synthetic analogue of growth hormone–releasing hormone (GHRH).
Is research-grade Tesamorelin the same as EGRIFTA WR?
No. EGRIFTA WR is a regulated prescription pharmaceutical product. Research-grade Tesamorelin supplied by third parties should not be represented as equivalent, interchangeable or approved for the same use.
What should buyers request from a Tesamorelin supplier?
Professional buyers may consider reviewing batch-specific COA, HPLC purity, identity data such as LC-MS where applicable, SDS, specifications and lot traceability.
