I am a few weeks into a cycle of test prop and tren ace at the moment. My concern is that the tren ace I got from a ugl,the oil inside my vials are not very dark. Every picture I have seen the oil is very dark in colour yet mine is a very light yellow. The other concern is that I am taking 1ml of test prop and 1ml of tren ace and I do not seem to be getting any side effects and I have been on cycle now for 3 weeks. My gains are suttle but this could be down to the prop as that is from a different ugl. What do you think Guys. Thanks.
