Question about Sermorelin reconstitution

The original vials stayed cloudy after mixing with 2 ml or 3 ml of refrigerated BAC water and after warming to room temperature. The same water worked fine on another peptide. Switching to a different brand of BAC water produced the same cloudy result with undissolved powder. One reply suggested the peptide may be sensitive to pH or water quality and advised testing a higher-grade BAC water before discarding anything; another proposed adding acetic acid to clear it.

• Cloudiness persisted across two different volumes of BAC water and after temperature adjustment.
• The same BAC water produced clear results with a different peptide.
• A second brand of BAC water also left the mixture cloudy with visible undissolved powder.
• Some peptides are noted as more delicate and may require attention to pH or water brand.
• Viscous or aggregated appearance was flagged as a reason to discard reconstituted vials.
• Adding acetic acid was suggested as a possible way to clear the solution.

Whether the cloudiness is caused by the peptide batch itself or by some other factor that was never tested.

Nothing here is advice.
