Parabolan is tren - just a particular ester (longer) than you have with tren acetate... Personally, I've tried every flavor and prefer Trenbolone Enanthate 200. It is the longest ester available, but is actually lighter than some of the others, i.e. you get more tren here than you would with Parabolan... I stack it with Test Enanthate 250, and inject 2 times per week (1ml tren + 2ml test), i.e. 400ml tren and 1,000ml test per week. I'll also add oxymetholone 50mg twice a day. Obviously, this is a bulking cycle... The mix of test and tren this way is a powerful combination - strength and bulk with enough water to save the joints.
The sweats suck, though... And drink a LOT of water...
