Chemical identity

What Tesamorelin is

Tesamorelin (research code TH9507; INN tesamorelin) is a synthetic linear 44-residue peptide amide. Structurally it is human GRF(1-44)-NH2 carrying an N-terminal trans-3-hexenoyl group on Tyr1; the amino-acid sequence itself is unchanged from the parent 44-residue sequence, and all residues are L-amino acids. Molecular formula C221H366N72O67S, molecular weight 5135.86 Da (average), CAS 218949-48-5 for the free peptide (the acetate salt is CAS 804475-66-9), UNII MQG94M5EEO, PubChem CID 16137828. The single sulfur atom corresponds to the Met at position 27. Pepta Labs lists tesamorelin as a lyophilized powder in sealed glass vials at 10 mg per vial, with reported RP-HPLC purity and identity confirmed by mass spectrometry. The salt form is typically acetate or trifluoroacetate. Store at 2-8 C on arrival or -20 C for long-term storage, protected from light and moisture. Offered strictly for laboratory research use.

Questions

Tesamorelin 10mg — common questions

What sizes of tesamorelin does Pepta Labs sell?

Only the 10 mg vial. Pepta Labs does not list a 5 mg, 20 mg or 30 mg tesamorelin vial; larger quantities are ordered as multi-vial packs of this same 10 mg vial, and the live pack options are shown on this page.

What exactly is in a Tesamorelin 10mg vial?

One sealed glass vial of dry, lyophilized tesamorelin powder at a supplier-stated 10 mg. The label identifies the compound, quantity and research-use designation; it carries no lot or batch number. Vial fill-quantity testing is not claimed, and net peptide content is not reported per listing.

Is this tesamorelin acetate?

Not stated. Tesamorelin is typically supplied as the acetate or trifluoroacetate salt, and this listing does not name the counter-ion present in the sourced production run. The identity figures on this page (C221H366N72O67S, 5135.86 Da) describe the free peptide, not the salt.

How do I get the tesamorelin certificate of analysis (COA)?

Request the analytical report on this page or email support@peptalabs.com with the compound name and quantity; it is sent by email, before you order if you want to see it first. It covers the sampled production run, not an individual vial, so it is a production-run report rather than a lot-specific certificate.

What does the tesamorelin report show?

Purity by reversed-phase HPLC, given as the main-peak area as a percentage of total peak area, and identity by mass spectrometry: the observed mass should agree with the calculated 5135.86 Da average mass. Sterility, endotoxin and potency testing are not claimed. The Learn guide How to Read and Verify a Peptide Certificate of Analysis (COA) walks through each section.

How should sealed tesamorelin powder be stored?

Keep the sealed vial at 2-8 C on arrival, or at -20 C for long-term storage, protected from light and moisture. It ships as dry powder at ambient temperature with no cold pack.

What does Tesamorelin 10mg cost?

Tesamorelin 10mg starts at $66.58 per vial. 3-vial packs are 7% off and 5-vial packs are 14% off. US shipping is free with no minimum.

What payment methods are accepted?

Pepta Labs accepts Cash App, Venmo, Zelle, Bitcoin and Ethereum (5% crypto discount). Payment instructions are emailed as soon as you place your order.

Is this for human or animal use?

No. Tesamorelin 10mg is offered solely for laboratory research and is not for human or animal use, consumption, administration, diagnosis or treatment. Buyers certify this at checkout.

How does tesamorelin differ from sermorelin?

Sermorelin is the 29-residue amide GRF(1-29)-NH2 (C149H246N44O42S, 3357.93 Da). Tesamorelin is the full 44-residue amide GRF(1-44)-NH2 with a trans-3-hexenoyl group on the N-terminal tyrosine (C221H366N72O67S, 5135.86 Da). They have different CAS numbers: 218949-48-5 and 86168-78-7.

What is the trans-3-hexenoyl group in tesamorelin?

It is a six-carbon unsaturated acyl group (C6H9O) joined to the N-terminal alpha-amine of Tyr1 as an amide. It adds 96.13 Da relative to the unmodified 44-residue peptide amide and is part of the structure identified by CAS 218949-48-5.

Which CAS number applies to tesamorelin?

CAS 218949-48-5 identifies the free tesamorelin peptide; CAS 804475-66-9 identifies tesamorelin acetate.
