Finished day 3 did shoulders. I took off yesterday but still had half a scoop of nitronox to maintain carnosine saturation levels. Today I took a full scoop felt stronger upped my shoulder press weight 10 lbs and looked pumped up. I feel like a beast in the gym. Once again just kept doing more and more sets. Also looking more cut nice muscle separation and vascularity. Im getting some looks too which is a great boost. Im actually waiting for someone to ask what im taking ill show them my nitronox blender bottle. I am also noticing I get arm pump alot easier. Just last night at work I was helping hold some piping up and my arms felt full and tight. Awesome product is all I can say.
