Totally get what you mean, the little crystals can be annoying. Hot water method is standard, no extra step needed.

I’ve had the same thing, just heat it up, swirl, and inject. The recrystallizing overnight isn’t really a problem.

Just be careful not to overheat. The hot water trick works, then use it before it sits too long. That’s what I do.

Some compounds are just like that. Don’t stress too much, heating and swirling right before use is usually fine.

If it clears up after heating, you’re good. Crystals forming later doesn’t affect it if you use it immediately.

You could try a slightly higher water temp, but honestly, the way you’re doing it is fine. Just use it after it clears.

I’ve had that happen before - if it goes clear with heat it’s usually fine to use right away, just annoying that it keeps crashing

Some batches just don’t like room temp tbh. Keeping the vial somewhere a bit warmer helped mine stay stable longer

As long as there’s no particles floating after heating you’re probably good, but yeah reheating every time gets old fast

Could be high concentration or solvent ratio causing it. Not really something you did wrong

I’d just warm it before pinning and use it while it’s clear - a lot of people do that with crash‑prone gear
