How Tesamorelin Works

Tesamorelin is a synthetic analog of GHRH(1-44) with a trans-3-hexenoic acid modification at the N-terminus that enhances stability and potency. It binds to GHRH receptors on anterior pituitary somatotrophs to stimulate GH synthesis and pulsatile release. It specifically targets visceral adipose tissue reduction through GH-mediated lipolysis and has been shown to reduce liver fat, improve lipid profiles, and reduce inflammatory biomarkers in HIV-associated lipodystrophy.

Research Applications

HIV-associated lipodystrophy (FDA-approved)
2
Visceral fat reduction
3
NASH and liver fat reduction
4

Reconstitution Calculator

Add this much bacteriostatic water:
2.0 mL
2 mg Tesamorelin + 2.0 mL BAC water = 1 mg/mL

Inject bacteriostatic water slowly along the vial wall. Gently swirl until dissolved — never shake. Store reconstituted solution at 2-8°C and use within 30 days.

Frequently Asked Questions

Tesamorelin (CAS: 218949-48-5) is a research compound, with a molecular weight of 5135.90 Da in the Growth Hormone / GH Secretagogues category. Tesamorelin is a synthetic analog of GHRH(1-44) with a trans-3-hexenoic acid modification at the N-terminus that enhances stability and potency. It binds to GHRH receptors on anterior pituitary somatotrophs to stimulate GH synthesis and pulsatile release. Researchers commonly investigate Tesamorelin for HIV-associated lipodystrophy (FDA-approved), Visceral fat reduction, NASH and liver fat reduction. Every vial from MiPeptidos includes batch-specific analytical documentation.
Tesamorelin is available in 4 sizes (2mg, 5mg, 10mg, 20mg), so reconstitution volume depends on which vial you have. For the 2mg size, add 1mL of bacteriostatic water; for the 20mg size, use 3-5mL. Always let the vial warm to room temperature first, inject the water slowly along the vial wall, and swirl gently — never shake. Store reconstituted Tesamorelin at 2-8°C and use within 30 days. MiPeptidos carries bacteriostatic water in 3mL and 10mL vials.
Tesamorelin is the largest GHRH analog at 5136 Da — it is the full 44-amino acid GHRH sequence with a trans-3-hexenoic acid modification at the N-terminus that improves stability. Sermorelin uses only the first 29 amino acids (3358 Da). Tesamorelin is FDA-approved for HIV-associated lipodystrophy, giving it unique clinical validation for visceral fat reduction. Its half-life (~26 minutes) exceeds Sermorelin (~10 minutes). MiPeptidos carries both in multiple sizes.
Store lyophilized Tesamorelin at -20°C for maximum long-term stability — properly stored, it remains potent for 24+ months. Once reconstituted with bacteriostatic water, keep it refrigerated at 2-8°C and use within 30 days. In research applications, Tesamorelin has a reported half-life of ~26-38 minutes, which informs dosing frequency and protocol design. Avoid repeated freeze-thaw cycles and protect from direct light. MiPeptidos ships every order with cold-chain packaging to maintain integrity during transit.
Every Tesamorelin order from MiPeptidos includes a batch-specific Certificate of Analysis. Our current batch (HR-TSMR-2600315, tested March 26, 2026) shows 99.6% purity by HPLC, mass spectrometry confirmation at 5135.90 Da, endotoxin levels below 0.1 EU/mg, and passing sterility per USP <71>. This level of documentation ensures you can verify compound identity and purity before beginning your research. MiPeptidos also offers bulk pricing on orders of 50+ vials — contact info@mipeptidos.com.
