Hahahahaha..... massive thread full of superb advice and the OP never came back... even fkn once!

Man, honestly, you're in way over your head with this one and don't even know it...
.
With your current BF, you're extremely more susceptible to side effects ranging from BP issues to estrogen related. Don't quote me here but there seems to be a correlation between BF% and estrogen activity, as well as with cardiovascular-related disorders.
.
This is realism even with your most basic compound: test. Masteron will yield a completely different, as well as similar set of sides. As will nandrolone.
.
Because you are a beginner, we try to take guys such as yourself thru a process so to speak. Starting with one compound; test, we are able to see how we react to it alone. We are also able to learn how to regulate other related processes like estrogen activity during our cycle. Although a good AI is key here, it's not always that simple. There is so much more to running a productive cycle than sticking that pin in your ass and hoping for the best. It's about educating yourself and listening to your body throughout the process, because what works for me may not work entirely the same for you.
.
Demonstrating proper execution of AI's and pct protocol tells me that the beginner is ready for the next, more complex cycle. Dealing with issues regarding side effects and such without complete correction tells me that the beginner is not ready and should continue working towards perfecting the same cycle. Jumping way too far ahead with conpound choices and still trying to make it work, tells me that my time and advice is not worthy to them.
.
Now I understand why the compound choices. But i still ask: why stick with them? Trust me when I say that you have yet to truly learn how you react to either anavar or test. You may remember the sides you dealt with, but I'm certain you cannot tell me which ones were related to which compound. So, with the addition to masteron and NPP, you will be faced with a set of side effects and no experience or clear understanding of how to manage and/or correct them.
.
Things like profuse sweating, shortness of breath, elevated HR at random, irritability, strong libido but unable to maintain an erection, or loss of libido and complete sexual dysfunction, how about waking up frequently not from sweating (that will prolly happen) but bc you have to pee several times a night. How will you know the cause and what will you do to correct them?
.
You won't know, so you'll hit the boards asking for help. You'll get some mixed information bc some of it will confirm what you suspect - wether accurate or not - and you will overlook the best advice of "drop the cycle and PCT", bc you desperately want to get it right and save your cycle.
.
I say all these things bc I have watched this same thing unfold many times almost the same way. So, you should ask yourself: why keep this cycle? Can I afford to save the gear for another run and go with a test only cycle? Do I really want to set myself up for a broken dick and milking bitch tits?
.
People highly underestimate what test is capable of doing for them, bc too much emphasis is placed on the gear itself. Truth be told, I can pick one cycle (test only or multi-compound stack) and depending on how i train and eat, I can either cut, bulk, or meet somewhere in the middle. Gear only accelerates the recovery processes. The gym stimulates them and the foods dictate the quality of the end result, not the gear.

I think u have some reading to do first dude. Most people can't just grab up a handful of compunds and pin them and get excellent result. Some people r lucky and get away with a jumbled up mess of compound or a dbol only cycle. U such as myself may be gyno sensitive and before u know it have a nice set of tits when u really wanted muscle. Muscles with tits don't look good on a man no matter how u stack. Do some research on long esters, short esters, look up steroid profiles, estrogen, anti estrogen, prolactin, look over other peoples cycle to help get a better idea of what compund r run with one another, bulking compunds, cutting compund, and diet just to name some. Read all u can before that first pin and u will be so much more please with tgo results, and want be as likely to grow those tits I mention earlier. I once thought juicing and getting big was just a matter of sticking a pin in my ass or popping dbol tabs. I WAS WRONG! I am not a pro by any means but I have came a long way and gained a lot of knowledge through it.

I agree with the bulk of the responses..

Get some Test E or Sus 250 with Deca 200.. Long active life.. Pin every 3 days...

I've used Mas.. I wouldn't recommend touching it until you BF is down in the LOW teens..

My big question I have is what is the result you are trying to achieve?

I don't know any Nandrolone Decanoate that is 100mg. You sure this isn't Nandrolone Phenylpropionate?
