No, what I said was that taking steroids and NOT lifting will make you gain more muscle than lifiting without steroids and that is exactly what the study shows.
That taking testosterone and sitting on your ass will make you bigger in terms of lean muscle mass than lifting natural.
Knowing those odds, I think it is fairly dumb to say things like 'steroids won't make you huge, you need hard work too', because actually you don't. You will still get bigger than you would from lifting natural. Of course, lifting AND taking steroids will make you hooge.
It varies greatly from individual to individual, some people are genetic freaks. It's rare, that's why not everybody is a professional body builder or else everybody that did roids would be huge 300 lb. mass monsters overnight but, it's not like that for the majority of people, it all has to do with genetics some people just respond way better to the compounds than others. Some people don't have to work as hard, some people can cheat more etc. unless you're a freak you do have to continue to work hard to see results. Really, it comes down to diet, you have to eat like a horse. The roids just help your body process the nutrition better than you could naturally. If it was easy as you make it sound, then nobody would have failed cycles but, it's not the case. This is not the site to find that type of information but, a lot of people have failed cycles when they first start out especially the ones that don't do the proper research and even then probably 9 out of 10 times these guys with the failed cycles discover that it was their diet, it's the food that makes you grow. You can have the baddest car in the world but, unless you give it fuel (ie: food) it won't go anywhere.
To the OP, you didn't state your goals. These are just tools if you're looking for a "software that does all that" you're not going to get anywhere. They just help you get to where you want to go faster but, you still have to put in the work.
HGH for gaining mass is not the best way, you have to take a lot of it a huge amount that will be very costly. Unlike most of the people here, I'm not an expert and will be upfront about it but, have done my fair share of research but, I might not recall everything accurately. So having said that, I believe to gain mass with HGH you have to be around 8-10iu a day if not more. Most pro's take HGH + slin together and of course other compounds but, nobody really runs HGH just on it's own (not to gain mass anyway).
HGH also doesn't come without it's own side effects, if you're in those huge doses of 10iu a day, again it varies from individual to individual but, many report sides of really bad CTS. You can also bloat up pretty bad, hold water. The cancer thing is true, if you have cancer it will make it worst. It can also make people insulin resistant, like myself I'm pre-diabetic and I had to stop taking GH because of my BG going out of control.
Most bodybuilders (not pros) that do take HGH will take it in the smaller amounts around 2-4iu a day and they aren't going to see increase in muscle mass from it so the effects they can expect are, fat loss and staying lean, better healthier looking skin, faster recovery from injury. Have also heard about it's effects in strengthening tendons (but I don't believe it's been proven) which is important to a lot of juicers because if you're growing too quick, your tendons can't keep up with the fast muscle growth and that's how injuries occur.
The other thing is you have to run GH for a long time to start seeing results. Minimum should be 6 months and preferably up to a year.
If you think you're ok with running 10iu a day for the mass let me give you a break down of what you might be paying. First of all there's lots of fake GH out there, assuming you can get a source for real GH it's going to be chinese underground pricing you could be paying about $200 for a 100iu kit and that's probably on the low end if you have a good hook up. So you'll be running that 6 months to a year. If you want US pharm grade underground pricing you could be paying close to a $1k for a 100iu kit and if you go through an anti-aging clinic probably 2-3x that.
Lastly again the HGH and these compounds are just tools, you're still going to have to train hard and most of all you're going to need to eat like a horse, without food nothing will happen. Also the thing is that you have to continue to eat like that, as was mentioned by somebody else here this happens to a lot of people they run a cycle and put on 20 or 30 lbs. and then they lose it all. It's because they don't keep up with their calories, say they started at 170 lbs. and they end up at 200 lbs. the problem is they are still eating like they are a 170 lbs. calories need to be adjusted and they need to be eating like a 200 lb. person but, they don't so they lose their gains and go back to where they were.
Again I'm no expert, I may not be 100% correct in some of the things I mentioned, but trying to add in what I can to the best of my knowledge at the moment.
