Heavy cream is the best IF you can stand the taste

Its always I want to gain fast.
Gaining weight is not fast.

Thanks but you go ahead and enjoy

My ex was one of those guys that liked to shave all over but he learned that in the military.
He was an Army Ranger and far from a beta male.
I would have preferred he let his chest and arm hair grow but it was his body so who was I to tell him what he can and cannot do?

I'm not hairy at all but I do keep the cooter trimmed.

Milkshakes are a great way to gain some weight.

Like I said everyone is different so there is no one right answer.
Your questions are basically un answerable.
You will never get the right answer for you until you actually do it.
When I first started it was really hard for me to gain because I was really thin to start with.
Once my metabolism slowed down is when I started to see gains come and the weight staying on.
That took a good 6 to 8 months to happen.
Seems some young people these days expect things to happen right now and they don't want to work for anything.

If you don't have time to put into it then you really don't want to gain and its a fantasy you are having.
Gaining takes time sometimes months even years plus dedication and effort on your part.
If you are not willing to put forth the effort then don't expect results.
10 days time you might gain 5 lbs at the most but when you stop you will lose it rapidly.
Heavy cream did the delay thing to me when I stopped drinking it.
It will put weight on you and IMO its the best product to get you to gain quickly.
Just don't expect 10 to 15 lbs in 10 days.

I never said those people aren't for real.
You missed where I said everybody is different so there is no set in stone kind of answer I can give you.
You won't know until you try it but all I am saying is don't expect much of a weight gain in ten days.
Try for 30 or or 60 days then you should see a difference.
You admitted to being new to all this right?
You are asking because you don't know.
I first started in approx 2006 so its been 14 years of experience for me so I do know something about weight gain.

First off yep that is a newbie way of thinking.
10 days is not near enough days to see any results.
Just because you take in X number of calories does not mean you will gain Y number of pounds.
Too many factors involved like your metabolic rate and how long it takes your body to adjust to the increased calorie intake.
How long it takes your body to process that increase .
No two people are the same so if you try to get all scientific about it then you are wasting your time.
When I first decided to gain it took 3 months of overeating and many days feeling absolutely ill from over consuming to see my weight go up and actually have the weight stick and not lose it .
There is way more to gaining than you realize and its not all that easy.
