No lah. It's not as a weight gainer. You're not reading properly.
The micronutrients is there to support & promote growth. Vitamins, minerals and other micronutrients are involved in many bodily functions, metabolisms, energy utilisation and immune system.
If tak cukup micronutrient, how to enhance your growth?
It's also to maintain your health. I don't suppose you are able to gain weight/mass when you're falling sick or aching everywhere all the time?!

You're not thinking straight, m8.

Due to the fact that you are building muscles and strength, whatever micronutrient you get from food may not be enough. And consider how nutritious our local food are... I don't think it's enough. It's enough for normal people who are not bodybuilding.

Besides, as your body weight & mass increase, don't you think you'll need more nutrients to support your increased weight/mass?

You body doesn't know the time...

BUT,
it is still able approximate the time. I can't be sure of the mechanism, but it's something related to the exposure to light and how it affects our biological clock.

It's not the exact time of 11pm-3am that matters. It's the time of non-exposure to intense light, and how long you are into the sleep that can affect your sleep and its cycle.

(This worked well, before the creation of electricity & light bulb, during the stone age =).

As for this idea: the first half of the sleep is for repairing, and the next half is for regaining energy.<-- I have no idea if it's correct or not.

True, if you take the steroid route.

'lbs' is a weight unit. It's called pounds.

1kg = 2.2 lbs. 5 lbs tub has 2.27kg of 'abc' inside it.
('abc' = whey, creatine, mass gainers, soy protein, milk powder, sand, salt, pepper, water, oil, gold coins, pixie dust, magic potion, elixir of life, etc.)

You don't need me to embarass you like this.
You could've searched it using Google first.
