- Before selecting a supplier, compare formulations based on purity verification, concentration flexibility, and reconstitution protocols. The table below contrasts three common approaches to tesamorelin + ipamorelin sourcing.
- Pre-Mixed Blend (Fixed Ratio)
- 1:1 or 2:1 (tesamorelin:ipamorelin)
- Rarely disclosed; typically bulk HPLC on API only
- Limited to 14 days (shortest peptide determines shelf life)
- None—locked into fixed ratio regardless of individual needs
- Convenient but suboptimal. Fixed ratios force either tesamorelin underdosing or ipamorelin waste. No titration possible.
- Separate Vials (Independent Dosing)
- Custom—user controls exact mg per injection
- Batch-specific HPLC provided per vial
- Tesamorelin 14 days, ipamorelin 28 days when stored properly
- Complete—adjust either peptide independently without affecting the other
- Gold standard for therapeutic outcomes. Allows dose titration, eliminates waste, preserves full potency of longer-lasting peptide.
- Compounded Multi-Peptide Stack
- Variable—often includes additional peptides (CJC-1295, GHRP-2)
- Inconsistent; depends on 503B facility SOPs
- 7–14 days; stability decreases with peptide count
- Moderate—can request ratio changes but limited by formulation complexity
- Over-engineered. Adding CJC-1295 (a long-acting GHRH analogue) to tesamorelin creates redundant pathway activation without added benefit. Complexity increases cost and instability.
- Our experience across hundreds of client protocols confirms that separate vials consistently outperform pre-mixed formulations. The ability to hold ipamorelin at 300mcg while titrating tesamorelin from 1mg to 2mg based on IGF-1 response and side effect tolerance is clinically significant—it's the difference between guessing at the right dose and knowing it through iterative adjustment. Pre-mixed blends eliminate this precision.
