Most cycles I see on here all have test as a base. Well, the ones from users I respect for their knowledge anyway. My first cycle was test only and I saw amazing gains and without side effects. My libido was through the roof as was my confidence and sense of well being. I think it just depends on your goals. Now I'm using Sustanon (sust), which is nothing more than Test with combined esters and Anavar. I chose Anavar due to the low sides and it's benefits as a cutting agent. However it does kill my libido and shin pumps when I run are brutal. Just remember good PCT. You don't want to jack your natural test production. I'm 45 and already have low test normally, so i'll be pinning my whole life, albeit at testosterone replacement therapy (TRT) dosages and I still make sure I do proper PCT.
