05Administration Protocol

Parameter
Adipotide
Tesamorelin
1. Route
Intravenous injection (systemic) in preclinical models. No human protocols exist.
Add 2.1 mL sterile water to 2 mg lyophilised vial. Roll gently — do not shake. Solution should be clear.
2. Formulation
Bioconjugate peptide. May also be encapsulated in nanoparticles (prohibitin-targeted nanoparticle formulation, KLA-PTNP, showed superior efficacy vs. free bioconjugate in mice).Hossen 2013
Subcutaneous — abdomen preferred. Rotate sites (avoid same spot within 2 cm). Avoid navel and waistband area.
3. Preclinical dosing
Low-dose systemic injection (exact dosing not specified in available abstract). Frequency and duration not detailed.Hossen 2013
Once daily. Preferred: evening, 2–3 hrs post-meal, before sleep — aligns with natural GH secretion pulse.
4. Storage
Not specified — likely requires peptide-grade lyophilised storage and reconstitution.
Lyophilised: room temp, light-protected. Reconstituted: refrigerate 2–8 °C, use within 21 days.
5. Needle
27–31G, 4–8 mm insulin syringe. Pinch skin, 45° angle for lean individuals.

06Stack Synergy

— no documented stacks
Tesamorelin
+ Ipamorelin
Strong
View Ipamorelin

Tesamorelin (GHRH analogue) and ipamorelin (GHRP / ghrelin mimetic) act on two distinct receptor systems to amplify GH release synergistically — GHRH receptor + ghrelin receptor. This dual-axis stimulation produces a more robust, sustained GH pulse than either alone while maintaining physiological pulsatility. Ipamorelin is highly selective with minimal cortisol or prolactin elevation, making it the preferred GHRP pairing.
