advice

So I injected 1 cc of sustain 250 and .5 of EQ into my belt to start my first cycle, now my shoulder is swollen and pretty tender... It's been 4 days now. It's not like I need to go to the hospital but any beginner advice would be appreciated... where to go from here? I need to be able to train...

Hey there guys I have just purchased myself some LGD-4033 still waiting for it's arrival. But my question here is if I do a LGD solo (Might pick up some S4 or MK-2866 along the way) will I be able to gain muscle mass whilst dropping body fat? I know this is a weird question and it might not...

I'm thinking about starting to stack s4 ,MK 677 and,gw-501516. Is this a good idea?what should I watch for? My diet is on point. My goal is to get leaner and put on a bit more muscle. Any advice for me?
