- Bacteriostatic Water Temp
- 2–8°C (refrigerated)
- 18–25°C (room temp)
- Temperature is the single most controllable variable. Refrigerate water for 2+ hours before use
- Mixing Technique
- Gentle swirling, vial rolled between palms
- Vigorous shaking or direct injection onto powder
- Shaking introduces air-water interface that denatures peptide at molecular level
- Lyophilised Peptide Age
- <6 months from synthesis
- >12 months from synthesis
- Older peptides oxidise slowly even at −20°C, predisposing to aggregation. Request recent batches
- Visual Appearance
- Crystal clear, no particulates
- Uniform cloudiness or fine suspended particles
- Cloudiness = aggregation, not contamination. Sterility unaffected but bioavailability reduced 40–65%
- Bioavailability
- 100% (baseline)
- 35–60% (reduced cellular uptake)
- Aggregates cannot cross cell membranes efficiently. Effective dose drops even if peptide remains chemically intact
