From your other thread: “I’m a 14 year old male, 5’5” and 122.5-125 lbs depending on the day"
You need precisely none of those supplements. None. Not the creatine, not the fish oil, not the BCAAs. None of the supplements you listed with do jack-all until you dial in your training and nutrition. From your other thread, it’s clear both of those still need work, so it’s a waste of time, energy, and money to consider supplements like these.
You don’t need to be thinking about “nutrient partitioning” or “keeping MPS elevated”. You need to be thinking about consistency (eating at least 3 meals a day, 7 days a week; training 3-5 days a week for the next 24 weeks) and thinking about the basics (basic lifting and a basic approach to nutrition). 3-hour workouts and looking to gain 1 pound a month will not get you where you want to go.
The fact that you’ve updated your training log once in the last 4 days is a small indicator that you’re not focused on the right things. You may have trained since then, but one reason for keeping a training log is to keep a training log. Consistency.
