OK, first piece of advice, please put those products away for a rainy day. There is no way that you are ready for them, based on your question. Not trying to bust your balls, but this is how I feel. If you want mass, these 2 aren't the products that you want. In all honesty, I am not going to offer any advice for these compounds just yet. I will give you some advice on adding mass the best way there is. Throuh proper training and diet, you will build far more muscle mass than just arbitrarily picking things. Keep the workouts to 4 days/week 45-60 minutes long. Chest on day 1, back on day 2, legs on day 3, rest day 4, arms/delts on day 5, rest the next 2 days. Keep the diet high in quality protein, moderate in complex carbs, moderate in fats (flax, fish oil, olive oil, etc). Do this for 8-12 months and then ask me that question.
