Tons of test
I think that honestly you might be taking too much test. If your last cycle was 700mg of test, why double it? You are taking double the dosage and in reality, you won't gain anything more than if you increased it moderately to say 900mg per week. The only thing you are increasing witha dosage like that is the chance for increased side effects. I am like 5'6" at 220 and fairly lean and I don't take over 100mg a day.
usually people that have trouble getting over a certain weight should focus in on their diet (most important), training, and sleep patterns. If you wanna shoot me a message with that info I would be happy to look them over and talk with you about anything that might stand out.
just be careful with your dosages bro.....getting big is never worth causing long term damage.
