thinkbig...i know it may seem like everyone is being really hard on you, thats because WE ARE. Seriously, there is a lot at stake here, you have done a really good thing by posting here and being honest, the tough part is that AA/AS have a HORRIABLE name in this world....a horriable skizo name. AA/AS are of the DEVIL himself but at the same time the are the MILK OF GOD for 40 year olds and over that goto their doc and cry, my pee pee isnt working, im depressed, i cant focus, everything is grey...can i have some TESTOSTERONE and the doc says SURE!
If you are going to be a part of this ORDER, KNOW YOUR SHIT or you will just be another prime time special on the evils of AA/AS...and you should start by LISTENING to bro's here. As many have said, you DO NOT KNOW ENOUGH yet, all of the information is on this forum just search.
Syst is a testosterone blend and test is test is test is test. The only difference behind the names is the durration they last in your system. Cyp and Enanth have VERY long esther's attached to them so that a shot will peak in about 48 hrs and taper very slowly for the next 3 weeks. This is great for a base but hard to regulate side's. On the other end of the spectrum theres Prop, it peaks within moments of the shot and is gone in a copule days, makes it easy to regulate sides but is a lot of stickin.
You need to research sides...if you say your 10 -15% your prolly 15 - 20%, the prob with that is simple....the aromitse enzyme has a GREAT relationship with fat...the more fat the more enzyme, that particular enzyme is responsible for converting test to estrogen and depending on your sensitivity to estro it could give you lactatting boobs in no time.
In a nutshell your first cycle should be 500mg of test a week and if you can get your hands on cyp, YOU WILL NEVER regret it. It is painless, shot your shoulders and chest with at 25g 5/8 - 1" pin. BE SURE TO HAVE adex or letro and nolva ready to go from the very beginning for side mgt...if you nips get puffy AND itchy take 40 mgs of nolva and 1mg of adex or equiv letro immediatly. Do this for 7 days then come off the nolva and just stay on the adex or letro. The nolva will block estro from binding to your nips immediatly while the adex will destroy a lot of the enzyme. If you are lucky you wont need any of this but error on the side of caution. Now for post cycle, there is a ton of thinking on this and it has changed in the last 5 years...i never come off so I havent looked at the latest, but to get you started your post cycle should start THE SECOND you detect nut shrinkage, even if its within the first 3 weeks of your cycle. You will need HCG. Take 500mcg of HCG once a week after you notice shrinkage. Then, 2 weeks after your last shot you start a 3 week taper with nolva, i dont know the dosages you will have to look that up. Along with the nolva, you will increase your HCG to something like 500mcg eod for the first week or so. The HCG brings your nuts back to testosterone production size and the nolva helps recover your HPTA (hypothalmic, pituitary, testicular axsis) which will be OUT OF WHACK and it takes a LONG time to get things right again.
You could expect with decent eating and workouts 30 lbs of total weight gain which will be ~15 - 20lbs of water which you will lose within 2 weeks of comming off and you will be lucky to keep 7 - 10 lbs of lean muscle if you do your post cycle therapy (pct) right.
BTW...how old are you?
Now i have given you the "Chapters at a Glance"...its up to you to read it.
