Well honestly I would look at these taking 250-300mg of test e a week and this sarm called gw-501516. That actually converts your fast twitch muscles into slow twitch endurance muscles! That also does not affect your cardio etc or lung capacity or blood pressure HOWEVER it is extremely dangerous! It is possibly the most dangerous thing to take BECAUSE IT CAN CAUSE CANCER IN 1 CYCLE ALONE. It is a strong beta receptor agonist. So strong it causes cancer lol. Fear not however as you can still stay completely safe on it! You will just need to take a strong beta blocker and believe it or notnbut the best one you can take is........ tribulus testris! It blocks 99% believe it or not which is even better than resveritol can say. And its commonlymbought really anywhere that sells supplements. The tribulus testris I mean. But you can expect crazy crazy crazy ammounts of endurance from it while gaining maybe 5 pounds of raw lean muscle on that cycle. Another interesting thing it does is actuqlly changes your bodies recomposition to take carbohydrates in first at lower levels of exercise rather than fat effectively making you ripped lol. Im not saying youll be 3% bf or anything but expect to go down to about 8 if youre at 10 or 11 jow. Also youll have to eat more because of that effect. You can get that sarm from a certain peptide supplier thats very fishy lol. Just check the names.also I would look at another great supplementcalled blox by bpi or bmi cant remember. That will increase your endurance dramatically in a week. Like lets saymyou do 60 push upsin a minute right? You canexpect 70 next time you try it without even training for it. I know because im in the air force too and I use it lol. Enjoy lackland!
