## Questions & Answers

**Q: How well does this work? I'm a teen with a high matabalizum and I'm looking to build mass and bulk up**
A: I’m nearly 50 years old, but seeing this question I had to comment.  Until I was around 32 or so, I couldn’t gain weight no matter how much I had to eat; or so it seemed.

I remember not caring whether it was fat or ideally muscle, I just didn’t want to be skinny anymore.

Then I hit a point in my life where the metabolism slowed and I couldn’t keep the weight off.  That lasted for nearly 15 years and for some reason my appetite suddenly plummeted and now I’m back looking at weight gainers simply to do nothing more than maintain a healthy weight.

Just try to keep in mind that human physiology typically prohibits putting on large amounts of muscle in a short period of time naturally.  That means that a large portion of quick gains will be fat.  Embrace your high metabolism and shoot for a reasonable goal.

That said, the more calories you intake in a day that exceeds what your body can burn, the quicker you will gain weight.  For the most part, it’s simple math.  Total Intake - Total Burned = Energy Stored Primarily as Fat.  There are about 3500 calories in one pound.  If you were to forge an extra 3500 calories a day, you could theoretically gain 7 pounds a week.  For someone like you, that probably means eating 8,000 calories a day.

Now as far as this product goes, it’s one of the highest calorie per serving gainers I have seen and it’s much quicker to pound a shake than to eat a steak!

Another thing to keep in mind is that supplements that are fortified with vitamins and minerals, have the potential to far exceed recommended safe values for human consumption.  I ran into this when I was your age.  I was drinking over a gallon of milk a day, milk is fortified with vitamin D and that build up led to some freaky painful headaches in me personally.

Too much calcium can also upset your bodies homeostasis and lead to surprising problems.

Being young, your body can handle a lot!  Just wanted you to be aware of the things I wish I knew when I was your age.

If I were young again I would focus on speed, agility and good clean ripped muscle!  Shredded muscle always looks bigger than fat muscle.

Cheers!

**Q: banana**
A: I’m adding my two cents.

Chocolate peanut butter is the truth. Banana was good at first, and then it wasn’t.

**Q: Does it work without work out ?because im so busy all day**
A: First off, I am so sorry that everyone that responded to this question this far hasn't answered your question. I'm seeing you ask if this helps you put on weight without working out. I've seen 3 or 4 people put "no excuses, no short cuts," "no motivation, no nothing" and other meat head answers. I apologize about them =)

Getting to your question. Yes, it does help you gain weight even if you're not working out. I understand you're busy...who's not? Working out and drinking this is without question the best way to gain weight. But, for the last 2 weeks I've been drinking a scoop in the morning, and a scoop at night before bed. And I've gained 3 pounds! Doesn't sound like a lot, but if I don't get 6 eggs every morning, I'll loose 2 pounds. If I don't eat 400 calories everyday, I'll loose 2 pounds. I have such a low fat to muscle ratio that if I type it in, people won't believe me, so ill save it for the haters on YouTube (jk) 😅 

But yeah, this stuff works. Might jist be a pounds a week, but if you're like me, that's great success. This does work without working out as long as you drink it consistently. Best of luck to you my friend.

**Q: will a high intensity sport like basketball plus weight training, 5 days a week  lessen the effectiveness of this product??**
A: The guy who says this causes cancer is lying or is just ignirant. Some other supplements may but even at that mant studies don't say which ones. Powder prorein supplements do not. As do many men, i don't use this product for muscle gain. I use max muscle for that. I use this for belly fat gaining.

*by T***F on February 28, 2012*

Started working out seriously June 2011 & had been using the 20 Gram Protien bars from Costco. Decided to step up to this. Was a little hesitant after reading some of the one star reviews, but had tried the Banana & thought it was ok. So far I'm about 70% through my first bag, using it right after working out & still use the protein bars on off days. The flavor's fine and the powder was fresh when it arrived so no complaints at all. The only possible downside is that I burp a lot after drinking it but that could be from air being incororated into the mix in the blender. As far as mixing, I blend in one scoop at a time to prevent lumps. Also, I only get some occasional muscle soreness after a hard workout ( working 4 sets to muscle failure ) and don't know if it's because the protein in this is absorbed quickly as they claim or not. Could be but who knows. I'm also up about 8 or 9 pounds since June ( a lot for me since I stated around 150 ) so everything together seems to be working. Short version is, yes, I recomend this stuff. March 22, 2012 Update. Had my annual physical. The blood test showed Creatinine High ( above range ) and protein in my urine. Doc said "If you're 18, that's ok, But.. ) since I'm "mature" (retired) that's not a good thing, and to reduce my protein intake, which I did by 1/3. So, just as a comment to all you "mature" people, your kidneys will love you more if you take in less protein than the directions recommend, even if you're working out hard (which I am). April 17th, 2012 update: Received my second bag last week. The flavor is not the same as the first. Not anywhere near as much banana flavor. Tastes a little "flat" Code on the bag is AO88364IJ. I'm guessing that's the lot number. Expiration date is 12/13. We'll see what the next bag is like.
