Invest in your diet/eat more.
Count your macros like you count your money in your wallet!
You can take creatine at any time you want, doesn't need to be after a workout only.
I highly, highly advise you to invest in your diet plan, no natural supplement will help you gain as your diet.
After you done that (years later), you can consider sarms and aas, then we can talk.
I don't think that he is diminishing the importance of diet at all.
He was simply asking a question about supplements.
As far as the mention of sarm's and aas, he posted his question in the natural bodybuilding section of the forum and also specifically said in his post that he does not want to take sarm's or aas. So I'm not sure where that part came from about 'then we can talk', but he had specifically said that he didn't want to use those.
The better a person's training and diet, the better they allow supplements to help them and work for them; but there are many, many people that because of various factors are never going to be perfect on their diets.
I'll use myself as an example - I haven't been able to train in over a year because I was in a very bad accident. I had really let myself go and lost a lot of muscle and gained a lot of fat for the year after the accident. In February, I started tightening my diet up, but for me, that is eating more like a normal person trying to eat clean than it is a bodybuilding type lifestyle. I started cleaning my diet up on Feb. 14th and started a very intensive fat loss supplement regimen, as of this morning, I've lost exactly 40 lbs. in just a little over 3 months.
That is without any exercise and without tracking macros - literally, I watch what I eat but I do not count calories. The only number I count at all is to make sure I take in enough protein.
Would I have lost weight without supplements? Yes.
Would I have lost more weight if everything with my diet was perfect? Maybe, maybe not; that's personal dependent.
Have I cheated on my diet and it cost me losing a few extra pounds? Yes.
Do I think I would have lost 40 lbs. in 14 weeks without an intensive supplement regimen with zero exercise? Absolutely not.
No one should diminish the importance of proper diet and exercise. But also, no one should diminish how much proper supplementation can help along with it.
