Would like to add some mass and some more strength. For me aesthetics are a welcomed side effect to strength.
From your stats your already a pretty big dude so I'm guessing you want to use a stronger compound.
Mostly people get suggested halo or epi or pmag/mechabol as a first cycle because their not as toxic as some of the other compounds on the market.
You are probably looking at more of a DMZ, M-Sten, Celtic Mass(diol PH to superdrol were the only ones on the market with it), or M1A. These are what we consider some of the heavier hitter compounds, would I say jump right off the deep end into a highly toxic M1A probably not. Do some research into these compounds and make a decision on one that you feel would suit your needs.
What ever you end up choosing I'd probably stack it with some Celtic Labs Trestobol.
Reasons being is that when you introduce exogenous hormones into your body that are not test, they don't do all the same things as test. While a lot of people thump run everything with test, not everyone wants to or is even able to pin test. Some of the options in that case are trandermal DHEA but this is a precursor hormone to many hormones in your body so it's direct conversion into test that great, others use Stano(epiandrosterone) which is a 2 step precursor to DHT which is more effective then nothing but not as good as test, next would be 4-dhea which is a direct 2 step precursor to test but dosing needed is high and 2 step conversion isn't the most effective method, lastly we have trestolone(Celtic Labs Trestobol) which is basically 7a methyl nandrolone, but it seems to perform the same basic functions in the body as test, as well as it's more anabolic then test and it's already an active compound no conversion needed and has decent oral bioavailability and being that it is a 19nor it will not 5a reduce into dht so things like hair loss are usually not a concern and it converts to estrogen which is good because if your running something that doesn't aromatize you can suffer from low estrogen side effects but you also have to mediate it's conversion so you don't suffer from high estrogen side effects.
Celtic Labs pretty much has most of the compounds on the market at some of the best prices, plus all our products are tested by PA so you know your getting what you pay for. As well as we have some exclusive compounds like dianodrol, dimethabold, Superdiol(celtic mass mentioned ealier), or compounds that are rare like Trestolone, or Protobol.
We are also constantly expanding and innovating in products we bring to the market not just copying.
