Tesamorelin + Ipamorelin Blend (10mg + 5mg)

What is the Tesamorelin / Ipamorelin Blend?

This research blend pairs two mechanistically distinct growth hormone secretagogues. Tesamorelin is a stabilized analogue of endogenous GHRH that stimulates GH release through the GHRH receptor on pituitary somatotrophs. Ipamorelin is a highly selective pentapeptide agonist of the growth hormone secretagogue receptor (GHSR) that stimulates GH release through an entirely separate signaling cascade with minimal effect on cortisol or ACTH.

Research Context

GHRH and ghrelin receptor pathways act synergistically, producing substantially amplified GH pulses when both are activated simultaneously compared to either alone. Tesamorelin's GHRH-receptor engagement is enhanced by Ipamorelin's GHSR stimulation, which sensitizes somatotrophs to GHRH input. Studies have documented elevated IGF-1, improved lean tissue mass retention, and reduced visceral adiposity in preclinical models using this combination.

Research Applications

• Dual-pathway GH secretagogue pharmacology
• GHRH receptor and GHSR co-activation studies
• IGF-1 axis amplitude and sustain research
• Body composition, lean mass, and visceral fat models
• Growth hormone pulsatility studies

For research use only. Not for human or animal consumption.

This compound's precise mechanism continues to be characterized through ongoing preclinical research. Investigators have proposed interactions with growth factor signaling pathways, receptor modulation, and cellular repair cascades. Consult current peer-reviewed literature for the most up-to-date mechanistic hypotheses.

Store lyophilized powder at −20°C for up to 24 months. Once reconstituted with bacteriostatic water, store at 4°C and use within 28 days. Protect from light, moisture, and repeated freeze-thaw cycles. Handle in a clean laboratory environment with appropriate PPE. For research use only, not for human or animal administration.

Use our Peptide Reconstitution Calculator to determine the exact volume of bacteriostatic water to add. Allow the solvent to run down the inside of the vial slowly, do not inject directly onto the lyophilized cake. Swirl gently; do not shake. The solution should appear clear to slightly opalescent.
