A reconstituted peptide vial is usually normal when the powder has fully dissolved after gentle swirling, the liquid is clear, and there are no visible particles floating in it. A small amount of foam right after mixing that settles on its own is fine, and copper peptides can show a blue tint when that color is expected for the compound. What should make you stop and look closer is cloudiness that does not clear, floating strings or particles, a cracked vial or damaged seal, or an unexpected color shift, plus any symptoms after use that suggest a reaction. When something looks off, the safe move is not to talk yourself into using it because the math worked out. Inspect it, compare it against what that specific compound is supposed to look like, and set it aside if it does not match.

Do not troubleshoot by injecting
If the vial looks wrong, do not use your body as the test. Check storage, label, COA, and vendor documentation first.
