- This is where confusion compounds. Plasma half-life (how long the peptide stays active in circulation) is not the same as solution stability (how long a reconstituted vial remains potent). Adamax's 30-minute plasma clearance doesn't mean your reconstituted vial degrades in 30 minutes. Peptide stability in bacteriostatic water depends on temperature, pH, and exposure to light and air.
- Reconstituted GHRP-2 stored at 2–8°C (refrigerated) maintains >95% potency for 28 days when prepared with sterile bacteriostatic water containing 0.9% benzyl alcohol. At room temperature (20–25°C), that window drops to 48–72 hours before measurable degradation begins. Freeze-thaw cycles accelerate breakdown. Each cycle can reduce potency by 5–10%, which is why single-use aliquots are standard practice in research settings.
- Unreconstituted lyophilized Adamax powder is far more stable. Stored at −20°C in a sealed vial with minimal air exposure, the dry peptide retains full potency for 24–36 months. This is the form we supply at Real Peptides. Lyophilized in sterile vials, third-party tested for purity and exact amino acid sequencing. Reconstitute only what you'll use within a 28-day research window.
- The practical implication: don't confuse how fast the peptide clears the bloodstream with how long your prepared solution stays viable. They're governed by completely different mechanisms. Enzymatic degradation in plasma versus hydrolytic and oxidative breakdown in solution.
