Trenbolone Acetate is the most common and it is not parabolan. Parabolan is Trenbolone Cyclohexylmethylcarbonate (which has been found to be kidney toxic). A better selection would be the Enanthate version which would allow for fewer injects, without the toxicity.
Boldenone also has several esters that can be attached. Undeclynate is the most common (EQ), but there is Propionate and Acetate versions of the compound.
I run most cycles short regardless of the ester. If you run 400-600 of deca for 4-6 weeks, it is still going to be with you for 7-9 weeks anyway. I like to hit cycles fast and hard, get out recover and repeat. I usually follow a 4-5 week on 10-12 week off pattern. Granted, I will never be as big as Ronnie... but I have a perfect lipid profile, low blood pressure and a fair amount of muscle for my frame. This works for me. I weigh 230-235 at 5' 10" and have about 9-10% BF. In the summer I cut to about 220. Although, each year that number climbs 5-10 pounds. 2 years ago, 210 was my cut weight, this year will be 220-225. I have learned to be patient... and my body has thanked me for letting it be healthy.
