Mans not hot with liquid creatine. Just go with the powder form is my opinion.
Anyway this is what I've experienced when I tried it.
With micronized creatine you can pretty much feel when you putting muscle mass/energy wise. Liquid creatine for me personally it took me way longer to even start feeling anything, however it has better side of holding less water, in terms of strong wise, liquid is a bit weaker. Plus on top of that it's expensive as fuck, for the price of 1 liquid creatine that will last you for 30 days you can buy 1 year worth of micronized creatine for whole year.
Still totally up to you. There's not much lab work on liquid creatine, however the powder form there's tons of studies out there that you can check.
