What is the Tesamorelin 5mg + Ipamorelin 5mg Research Bundle?

This two-vial research bundle combines Tesamorelin 5mg and Ipamorelin 5mg. Tesamorelin is a modified 44-amino-acid GHRH analog used to study receptor activation and downstream growth-hormone-axis signals. Ipamorelin is a modified five-residue peptide studied as a selective GHS-R1a, or ghrelin-receptor, agonist.

Together, the set supports controlled work across GHRH-receptor and ghrelin-receptor signaling using matched 5mg vial strengths. Each retail product stays in its own lyophilized vial, so the bundle does not create a new formulation or establish a proven combined effect.

How It Works

Tesamorelin models GHRH-receptor signaling: Receptor engagement supports controlled measurement of cAMP-linked pituitary and downstream pathway markers.

Ipamorelin engages GHS-R1a: This ghrelin-receptor route provides a defined growth-hormone-secretagogue signal in experimental models.

Separate vials protect experimental control: Study either retail product independently or compare their distinct signals without treating the bundle as one formulation.

Why Source from 321 Peptides?

Domestic accountability.

All included compounds are synthesized, manufactured, formulated, finished, and packaged in Certified GMP laboratory facilities in California and Arizona—never sourced from overseas or Mexico. That creates direct domestic supply-chain accountability from production through fulfillment.

Verification you can inspect.

Independent third-party HPLC evaluates each compound against its ≥99% purity target, while mass spectrometry confirms molecular identity. For each vial, the results are documented in one combined, batch-specific Certificate of Analysis report.

Protected in transit.

Every included product is freeze-dried to help preserve stability during storage and shipping. Rapid domestic fulfillment reduces unnecessary time and handling.

Frequently Asked Questions

What comes in the Tesamorelin 5mg + Ipamorelin 5mg bundle?

The bundle includes one Tesamorelin 5mg vial and one Ipamorelin 5mg vial. Each product arrives separately in lyophilized form with batch-specific COA documentation.

What research pathways are represented in this bundle?

The bundle spans GHRH-receptor and ghrelin-receptor signaling using matched 5mg vial strengths. Each compound retains a distinct experimental profile, and the bundle does not establish clinical synergy.

Are these FDA-approved prescription products?

No. Some included active ingredients also appear in FDA-approved finished medicines, but the research vials in this bundle are not those approved products or substitutes. Every vial is supplied exclusively for controlled, non-clinical research.
