No. [Tesamorelin](/product/tesamorelin-5mg) is not [ipamorelin](/product/ipamorelin-5mg). They sit in the same broad secretagogue conversation, and that is why requisitions swap them. The sequences, the catalogue lines, and the literature targets are different.
Tesamorelin is a synthetic analog of growth hormone-releasing hormone. The registry number on this catalogue is CAS 218949-48-5. Early papers also use the development designation TH9507. Those two names reconcile to the same CAS. They do not reconcile to ipamorelin. VaultLabs supplies tesamorelin as Tesamorelin 5mg and a 10 mg fill on the same product page. The fills do not share a lot or a certificate. Chemistry is on the tesamorelin monograph. Ordering notes are on tesamorelin in the UAE.
Ipamorelin is a five-residue synthetic peptide: Aib-His-D-2-Nal-D-Phe-Lys-NH2. It includes a non-proteinogenic residue and two D-configured residues, and it is C-terminally amidated. The literature places it at the ghrelin receptor GHS-R1a, which is a different receptor from the GHRH receptor. The standalone SKU is Ipamorelin 5mg. The monograph is ipamorelin, and the UAE page is ipamorelin research peptide UAE.
The third vial people mean by accident
There is also a blend: CJC-1295 (no DAC) 5mg + Ipamorelin 5mg. That vial holds two sequences, 5 mg of each, and it has no single CAS that describes both. Tesamorelin is not one of the two sequences. A 5 mg figure appears on the tesamorelin vial and inside the blend name, which is enough for a wrong receipt if the line only says “5 mg secretagogue.”
CJC-1295 versus tesamorelin already separates tesamorelin from the CJC line. CJC-1295 / ipamorelin blend specifications covers the blend as a blend. This page is the direct tesamorelin-versus-ipamorelin question those two pages leave open.
| Tesamorelin | Ipamorelin | |
|---|---|---|
| Class | GHRH analog | Ghrelin-receptor pentapeptide |
| Sequence on this site | Stated on the lot certificate | Aib-His-D-2-Nal-D-Phe-Lys-NH2 |
| CAS | 218949-48-5 | Not printed as a single substitute for the sequence |
| Literature target | GHRH receptor | GHS-R1a |
| Catalogue | 5 mg and 10 mg vials | 5 mg vial, also 5 mg inside the CJC blend |
What “same family” does not allow
A shared research theme is not a substitution rule. Tesamorelin was characterised as a stabilised GHRH analog. Ipamorelin was characterised as a selective ligand at a different receptor, and its unnatural residues are part of why it is not a routine L-peptide. Publishing both in one review article does not make the vials the same SKU.
Pharmaceutical tesamorelin products exist under specific indications in some markets. Those finished medicines are not this lyophilized research vial. VaultLabs supplies laboratory reference material. The research use policy is the scope.
How to receive the right 5 mg
Write the full name. Then match:
- Tesamorelin, ipamorelin, or CJC-1295 (no DAC) plus ipamorelin, exactly as ordered.
- Nominal mass. Tesamorelin 5 mg is not tesamorelin 10 mg. Ipamorelin 5 mg alone is not the blend’s 5 mg of ipamorelin beside 5 mg of CJC-1295.
- Lot on the vial and lot on the certificate.
- Identity field. For ipamorelin, the pentapeptide sequence when the certificate prints one. For tesamorelin, CAS 218949-48-5 or TH9507 mapped to that CAS. For the blend, both component names, not one purity figure covering both.
Use batch verification on the printed lot. How to read a peptide COA is the next pass. An unpublished lot stays in quarantine under a documentation request.
Sealed vials are stored at 2–8 °C, protected from light, and UAE parcels should go into cold storage at receipt. The peptide calculator converts a mass and a volume after the SKU is already correct. It does not decide between these peptides.
What this page will not decide
It will not say which receptor a method should address. It will not convert a literature description into a preparation instruction. If the protocol names tesamorelin, order the tesamorelin fill and file CAS 218949-48-5. If it names ipamorelin alone, order the standalone 5 mg vial. If it names both CJC-1295 without DAC and ipamorelin in one container, order the blend and file that lot.
