Quick Answer
Tesamorelin 5 mg / 10 mg vials, bulk powder & dual-CAS verification: quick sourcing answer
B2B sourcing noteTesamorelin (TH9507) circulates in B2B trade under two valid registry identifiers: CAS 901758-09-6 for the lyophilized acetate salt (~5,196 Da nominal monoacetate) and CAS 218949-48-5 for the anhydrous 44-AA free base (~5,135.9 Da observed in ESI-MS). Distributors ordering 5 mg or 10 mg unlabeled vials or gram-scale raw powder should confirm both RP-HPLC purity and weight-adjusted net peptide content before comparing quotes.
Naming comparison table

B2B specification review table
| Review item | Buyer check |
|---|---|
| Available B2B formats | Unbranded 5 mg and 10 mg lyophilized 10-vial kits (3 mL Type I neutral borosilicate glass), custom OEM runs, and gram-scale bulk powder. |

Why buyers trust WUMO
Real content, documented — not guesswork
In peptide sourcing, chromatographic purity and delivered quantity require separate evaluation. We keep purity and labeling basis distinct on available documentation, so buyers can review analytical parameters for their quoted batch before ordering.
Purity vs quantity distinction
Purity (%) and reported quantity are distinct analytical parameters. Review purity and reported quantity separately, and confirm the labeling and assay basis for the batch proposed for your order.
Batch-specific documents
Batch documentation reflects the specific lot produced. Ask which batch-specific documents are available for the quoted lot, including COA and supporting HPLC or MS records where applicable.
Documented before commitment
Ingredient identity (INCI / CAS), specification sheet, and SDS are available for technical review. Confirm documentation for the batch proposed for your order before purchase.

Overview
Overview
Tesamorelin Acetate (TH9507) is a synthetic 44-amino-acid GHRH-analog peptide, supplied here as a research-use raw material for qualified B2B buyers. It is available as bulk lyophilized powder (by gram) or in lyophilized vial format, with batch-specific documentation, specification review, and packaging discussion.
Material is acetate form (CAS 901758-09-6; free base 218949-48-5), >99.3% by HPLC, with LC-MS identity confirmed against the target mass (~5135.9 Da free-base equivalent; acetate salt basis ~5196 Da). Research-grade is standard; API-grade is available under a signed quality agreement. Typical lead time is approximately 20 days, subject to batch and order scope.

B2B Review Guide
Tesamorelin Acetate Raw Material & Lyophilized Vial for B2B Research Supply
Tesamorelin Acetate is offered by WUMO Peptide as a research-use raw material — bulk lyophilized powder by gram, or lyophilized vial format — for qualified B2B sourcing projects. It is a synthetic 44-amino-acid analog of growth hormone-releasing hormone (GHRH / GRF(1-44)) and is discussed in laboratory research contexts involving peptide identity, purity, and analytical documentation.
Two CAS numbers appear in the market: 901758-09-6 (acetate, the form supplied here) and 218949-48-5 (free base). The widely quoted ~5135.9 Da is the free-base equivalent; the acetate salt basis is ~5196 Da. Confirm the salt form and the molecular-weight basis on the batch COA so that quotes and LC-MS results reconcile. Purity is >99.3% by HPLC, with peptide content reviewed separately from purity.
For B2B customers, the key review points are batch-specific specification, HPLC purity, LC-MS identity, documentation scope, format (bulk vs vial), packaging, and lead time (approximately 20 days). Available documentation includes COA, SDS/MSDS, specification sheet, HPLC report, and LC-MS report. Research-grade is standard; API-grade is available under a signed quality agreement, and a third-party verification report can be provided where authorized.
Tesamorelin Acetate supplied through this page is intended for laboratory research use only. It is not supplied for clinical use, therapeutic use, compounding, injection, human use, resale to consumers, or any unapproved application.

FAQ
Frequently Asked Questions
What is Tesamorelin Acetate?
Tesamorelin (development code TH9507) is a synthetic 44-amino-acid GHRH / GRF(1-44) analog with an N-terminal trans-3-hexenoyl modification, supplied here as the acetate salt. CAS 901758-09-6 applies to the acetate and 218949-48-5 to the free base.
Is Tesamorelin Acetate supplied for human use?
No. It is supplied as a research-use raw material for laboratory research and B2B sourcing projects. No dosing, administration, reconstitution, or human-use guidance is provided, and WUMO Peptide is not affiliated with any branded tesamorelin drug product.
What documents can be provided with Tesamorelin Acetate?
COA, SDS/MSDS, specification sheet, HPLC report, and LC-MS report, batch-specific. Purity is quoted at greater than 99.3% by HPLC on the batch-specific COA.
Can WUMO Peptide support private label packaging for Tesamorelin Acetate?
Neutral vial, box packaging, or selected private-label options can be discussed for qualified projects. Labeling and market compliance remain buyer-side responsibilities.
What specifications should be confirmed before ordering?
Salt form (acetate or free base), the molecular-weight basis used on the COA (~5135.9 Da free-base equivalent versus ~5196 Da acetate salt basis), purity stated separately from peptide content, format (bulk powder by gram or 2 / 5 / 10 mg vial), and lead time, which runs approximately 20 days subject to batch and order scope.
Do you supply Tesamorelin in 10 mg lyophilized vials as well as 5 mg vials and bulk powder?
Yes. Qualified B2B distributors and private-label brands can request unbranded 10 mg or 5 mg lyophilized vials in Type I neutral borosilicate glass (10-vial white divider kits), scheduled custom-fill runs, or gram-scale lyophilized raw powder.
Why does LC-MS report ~5,135.9 Da when the COA cites Tesamorelin Acetate (CAS 901758-09-6)?
Non-covalent acetate counter-ions dissociate during electrospray ionization, so ESI-MS measures the covalent 44-AA trans-3-hexenoyl free-base peptide (~5,135.9 Da average mass), while acetate salt content is reported separately on the COA.
