If I want to grow muscles, is taking creatine a must or can I take whey protein only?

Neither creatine or whey protein are a must but creatine is the most well researched supplement and has clear benefits and not just with muscle building.

First and foremost you need to get in the good workouts and eat a healthy diet with excess calories and plenty of protein. If you have any difficulties with getting in enough protein then taking whey protein or even casein protein can be useful. But if you are able to get in your protein macros through food alone then that would be fine.

What I've noticed from creatine is that it enables me to tense my muscles harder for some reason. I notice the biggest benefits when I deadlift or bench. I'm able to get more tense at the start of the lift and it enables me to hold more weight. Being able to tense more allows me to lift more which allows me to give a bigger stimulus for my muscles to grow.

Hello, I have a question about astral projection. I started to get interested in this a little while after my mum passed in april. I thought I may be able to see her and speak with her if I managed to achieve astral projection. Since this interest, every time i sleep on my back I go into sleep paralysis. However, I cant progress into astral projection because it is very scary for me as I feel like I'm suffocating when this happens. I panic and force myself to wake up. This only ever happened about once a year before this. It sometimes lasts a long time. This has happened about 3 times per week since my mum died, as mentioned on a previous post. I no longer try to go into it anymore(due to the suffocating feeling), but it still happens. I read that sleep paralysis is the pathway to astral projection. Why has this started to happen so frequently since simply taking an interest in it? Is this connected to the afterlife? I am concerned about it as I now cannot seem to stop this happening. Could it be my mum trying to communicate? Im asking due to more knowledge around this in this group.

Creatine has better benefits for the money than any other muscle building supplement. I buy 500 grams of micronized creatine monohydrate for $40 and it lasts for 100 days. Just take 5 grams every day. It doesn't even matter what time of day you take it.

I don't know all the particulars of the research but I've also heard that creatine has cognitive benefits that might actually be greater than the muscle building benefits. Personally I have a history of concussions so I continue to take creatine for that benefit.
