What Is the Tesamorelin Ipamorelin Blend?
The tesamorelin ipamorelin blend is a pre-mixed research vial containing two growth hormone secretagogues lyophilized together: 13mg of tesamorelin and 3mg of ipamorelin. It is sold as a tesamorelin/ipamorelin blend, a tesamorelin and ipamorelin stack, or simply tesamorelin plus ipamorelin; all describe the same pairing.
Tesamorelin is a synthetic analogue of growth hormone releasing hormone (GHRH) that keeps the full 44 amino acid human sequence, capped to protect it from breakdown. Ipamorelin is a five amino acid peptide that activates the ghrelin receptor, first described as the first selective growth hormone secretagogue because it releases GH with little effect on cortisol.
Tesamorelin and Ipamorelin Together: Why Stack Them?
Can you stack tesamorelin and ipamorelin? In research, that is exactly why they are paired. The pituitary's somatotroph cells have two separate receptors that trigger growth hormone release: the GHRH receptor, which tesamorelin activates, and the ghrelin receptor (GHS-R1a), which ipamorelin activates. Research on combining a GHRH analogue with a ghrelin agonist has long reported a larger GH release than either pathway alone.
So tesamorelin and ipamorelin are not alternatives to each other so much as two halves of one mechanism. For a straight comparison of the two compounds on their own, see our ipamorelin page.
The 13mg + 3mg Ratio
Most GH secretagogue blends split their peptides evenly. This one does not. With 13mg of tesamorelin to 3mg of ipamorelin, roughly 81% of the vial is tesamorelin, which makes it a tesamorelin-led blend with ipamorelin in a supporting role. It suits protocols built around tesamorelin's clinical literature that add a smaller ghrelin receptor signal, rather than protocols that treat both pathways equally.
If your study needs the two in equal amounts, or a ratio of your own, buy the tesamorelin 10mg vial and the ipamorelin 10mg vial separately.
Tesamorelin Ipamorelin vs CJC-1295 Ipamorelin
Both of our ipamorelin blends pair it with a GHRH analogue. The difference is which analogue, and in what proportion.
| Tesamorelin + Ipamorelin | CJC-1295 + Ipamorelin | |
|---|---|---|
| GHRH analogue | Tesamorelin, full GHRH (1-44) | CJC-1295 No DAC, GHRH (1-29) |
| Ratio | 13mg + 3mg, tesamorelin-led | 5mg + 5mg, equal |
| Total fill | 16mg | 10mg |
| Clinical background | Tesamorelin has an FDA approval (Egrifta) | Research compounds |
| Chainwell blend | This vial | CJC-1295 and Ipamorelin Blend |
Our recommendation: choose the CJC-1295 ipamorelin blend for an equal-parts pulsatile protocol, a widely used pairing in GH secretagogue research. Choose tesamorelin ipamorelin when your work is anchored in tesamorelin's literature and you want ipamorelin as a secondary signal.
CJC-1295, Ipamorelin and Tesamorelin Together
Some suppliers sell a three-way tesamorelin, CJC-1295 No DAC and ipamorelin blend; we do not stock one. Worth knowing before you buy one elsewhere: tesamorelin and CJC-1295 are both GHRH analogues acting on the same receptor, so combining them doubles up one pathway rather than adding a new one. Our view is that a study is easier to interpret with one GHRH analogue plus ipamorelin. If your protocol does call for all three, buy tesamorelin, CJC-1295 No DAC and ipamorelin as separate vials so each can be measured and adjusted.
Reconstituting the Tesamorelin Ipamorelin Blend
Let the vial reach room temperature, wipe the stopper with an alcohol swab, and add bacteriostatic water slowly down the inside wall with a U-100 insulin syringe. Swirl gently until clear; do not shake. As a worked example, 2 mL of water gives 6.5mg of tesamorelin and 1.5mg of ipamorelin per mL. Keep the reconstituted vial at 2 to 8 °C, protected from light, and use it within 28 days. Our reconstitution guide and calculator covers other volumes.
Lab-Tested Tesamorelin and Ipamorelin With a COA
A blend has to be verified for both peptides, and a 13 to 3 ratio makes the smaller component easy to overlook. Every Chainwell Peptide tesamorelin ipamorelin lot is sent to an independent laboratory before release and tested for identity and purity, and a lot that does not meet specification is not sold. The lot number on your vial links it to its report on our COA lookup page.

Tesamorelin and Ipamorelin Blend FAQ
What is the tesamorelin ipamorelin blend?
+
It is a research vial containing 13mg of tesamorelin, a full-length GHRH analogue, and 3mg of ipamorelin, a selective ghrelin receptor agonist, lyophilized together. The two act on separate pituitary receptors that both trigger growth hormone release. Chainwell Peptide supplies it with a lot-matched certificate.
Can you stack tesamorelin and ipamorelin?
+
In research they are paired precisely because they act on different receptors: tesamorelin on the GHRH receptor and ipamorelin on the ghrelin receptor. Studies combining the two pathways report a larger growth hormone release than either alone. The blend holds both in one vial.
Is tesamorelin ipamorelin better than CJC-1295 ipamorelin?
+
Neither is better in general; they suit different protocols. The CJC-1295 ipamorelin blend is an equal 5mg + 5mg split for pulsatile research. The tesamorelin ipamorelin blend is 13mg + 3mg, tesamorelin-led, for work built on tesamorelin literature.
Can you take CJC-1295, ipamorelin and tesamorelin together?
+
Chainwell Peptide does not stock a three-way blend. Note that tesamorelin and CJC-1295 act on the same GHRH receptor, so combining them duplicates one pathway. If your research protocol calls for all three, buy them as separate vials so each can be measured and adjusted.
How do you reconstitute the tesamorelin ipamorelin blend?
+
Add bacteriostatic water slowly down the inside wall and swirl gently until clear, without shaking. 2 mL gives 6.5mg tesamorelin and 1.5mg ipamorelin per mL. Store the reconstituted vial at 2 to 8 °C, protected from light, and use it within 28 days.
Where can I buy tesamorelin and ipamorelin in Australia?
+
You can buy the tesamorelin ipamorelin blend in Australia from Chainwell Peptide, or each peptide as a separate 10mg vial. Every lot carries a lot number matched to an independent certificate of analysis, and orders paid before 3pm on a business day ship the same day.
