However, and I only offer my opinion with some tough love: YOU (not me or anyone here) and those who care about you or live with you need a better answer than "to gain some weight and look jacked" for using such powerful drugs in such large amounts that carry risk--in some cases, hefty risk.
If your answer was that you have great genes and/or talent and have some evidence that there is a high chance that you can make it to the IFBB pro or elite athletic ranks or were going to be highly paid from playing the roles of freaks in movies and you work full time with health insurance benefits (to clean up your own mess and not rely on anyone else if one were to occur), then I'd understand. But just to be big for the sake of it, I can't see tampering with one's health to such a degree as are you.
But to each his own. Just remember: you play, you pay.
Anyway, in the case you will continue to juice, wouldn't it make sense to make gains on modest amounts and only graduate to larger amounts when the smaller amounts no longer yield gains? That's what the smarter guys I know did. You also might feel better.
Again, I'm no expert nor do I have the experience with gear. So I guess you can do as you please.
