- Amino Acid Sequence
- D-Ala-D-β-Nal-Ala-Trp-D-Phe-Lys-NH2
- Identical. No structural difference
- Receptor Binding Affinity (Ki at GHS-R1a)
- ≈0.7 nM
- Equivalent binding potency
- GH Secretion Amplitude
- Pulsatile release peaking at 30–60 min
- No performance difference
- Lyophilized Powder Stability (12 months at 25°C)
- ≥98% purity retention
- 92–95% purity retention
- Acetate shows slight edge in long-term storage
- Reconstitution Time
- 30–60 seconds
- 1–3 minutes (transient turbidity)
- Acetate dissolves faster, both fully soluble
- Professional Assessment
- Preferred for long-term storage; marginally faster reconstitution
- Functionally identical once dissolved; slightly more prone to humid degradation
- Choose acetate for storage convenience; both perform identically in-protocol
