Tesamorelin / Ipamorelin 3 mL Pen

The Science, Simplified: This is a dual-peptide research blend combining Tesamorelin (synthetic 44-amino acid GHRH analog with N-terminal trans-3-hexenoyl modification) and Ipamorelin (selective growth hormone secretagogue / ghrelin mimetic).

Product Specifications – Tesamorelin / Ipamorelin 12 mg / 3 mg 3 mL Pen

  • Total Tesamorelin: 12 mg
  • Total Ipamorelin: 3 mg
  • Volume: 3 mL pre-filled pen
  • Clicks in the pen: 300
  • Volume per click: 0.01 mL
  • Dial range: 1–60 clicks per dispensing (0.01–0.60 mL)
  • Peptide per click: 40 mcg Tesamorelin + 10 mcg Ipamorelin
  • Concentration: ≈4 mg/mL Tesamorelin + ≈1 mg/mL Ipamorelin
  • Purity: Research-grade, third-party tested (COA available)
  • Format: Ready-to-use multi-dose pre-filled pen

Key Research Focus: Growth hormone release research.

Physical Form & Solubility:

  • Appearance: Clear to slightly opalescent liquid
  • Solubility: Already in aqueous solution (acetate salt form for optimal solubility and stability). Highly soluble; no reconstitution required.

Pen Format Details: The 3 mL pre-filled pen is a sterile, multi-dose delivery system designed for precise, consistent dispensing of the research blend. It features a sealed cartridge, dial-a-dose mechanism for accurate volume control, and a fine-gauge needle interface. The pen is ready for immediate laboratory use with no mixing or transfer steps required. Each pen is labeled with total peptide content and lot-specific COA reference.

Stability & Handling Notes:

  • Refrigerated at 2–8°C (36–46°F). Practical shelf life is 4–6 weeks when protected from light and handled with aseptic technique.
  • Do not freeze. Avoid prolonged room-temperature exposure.
  • Discard after 6 weeks or if the solution becomes cloudy, discolored, or shows particulate matter.
  • Protect from light and moisture at all times.
