How should sculptra look when diluted in the syringes?

An injector I’m going to use says sculptra will look crystal clear, like water or saline in her syringes, as the sculptra fully dissolves and it will look like clear water after 24 hours. However, with other injectors I’ve used it never looks crystal clear, it looks cloudy or there’s some particles/ powder swimming about in the solution as it’s just diluted and not dissolved like she says. She also says it’s 4ml Solution she administers, but I thought it was 5 -8ml per vial? Please advise !
