There are particles at the bottom of my reconstituted vial of 100mg GHK-Cu with 3ml bac water. There are still some "stuff" floating around, its probably because of my low bac water right? It was just reconstituted and another vial has the same thing, so it can't be bacteria. Could it be bad purity?

Do different types of grip actually affect the recoil? Like are RK grips better than SAW foregrip? And if yes, which is the best?
