Im working on that. Still reading thru a few things and seeing what the best options are. I know its all a gamble. If something doesnt feel right, ill stop cycle.
At least your asking which is great. But putting the gamble aside, running a compound that has low sides and yields results is recommended for first use.
This will be your stepping stone for future cycles, everyone of them.
If your diet is off and training is just average the results your are expecting will obviously be limited and dismal.
Using less harsh compounds will also allow you to deal with the sides vs just stopping all together.
This will also give your body a chance to react to what you are taking and will allow you to change your diet/training easier.
Don't rush it and fall into the "I'll be on the cover of muscle and fitness in weeks" mentality because that just doesn't happen.
Start slow and learn from there.
