indeed it is..with these compounds at question here, in most cases any given individual will use one or the other for a completely different goal in mind..or because one was more cost effective or readily available at the moment..one is not going to be better than the other when asking a personal preference.. different goals,different level in fitness, so many variables in the equation here..
Look wise if thats all your taking about here....I looked blocky and big on deca a very wet look. Tren gave me in my opinion a better quality look. I used tren to bulk. I prefer tren but im giving deca another shot next blast and will be taking better note of diet. I can look back on past pics and tell exactly which was taken when I had 10+ weeks of deca in me.
