This was not in my plan. It was a last-minute addition. Best decision I made that month.
I wasted money on marketed products. Packaging does not build muscle.

Optimum Nutrition Micronized Creatine — My daily pick
I have been taking this creatine for four years. One scoop, a glass of water, every day. No cycle, no loading, no complication. My daily pick.
What I like:
- Pure creatine monohydrate
- Mixes easily
- Unflavored — add it to anything
My verdict: If you only take one supplement for muscle, take this one.
Thorne Creatine — When you want maximum purity
I discovered Thorne when I was looking for a creatine without trace contaminants. Their NSF Certified for Sport seal is the best on the market.
What I like:
- NSF Certified for Sport
- Gluten-free and non-GMO
- Tested for banned substances
My verdict: For tested athletes or those who want the highest quality.
Legion Recharge — Recovery included
After an intense leg day, my muscles used to remind me for three days that I had lifted heavy. Recharge cut that time in half.
What I like:
- Creatine + carnitine
- Helps recovery
- Pleasant Fruit Punch flavor
My verdict: If you want creatine plus recovery in one product.
My final verdict
Do not forget: the supplement helps, but you do the work. Not the other way around.
