How can you say comparing Sustanon to Ara is a better example,ara is ethenate where stens contain 25mgs. prop. and 100mgs. cypinate? not to flame but sten contains no ethenate, they are cheap and a very thin oil so it absorbs fast so you need to do 3 or 4 amps a week but for $8. for 2 amps is not a bad choice for me and cypinate and propenate are my two favorite tests...i like it as long as you get it for under 6.00 bucks an amp..its a nice cheap cycle if you can get say some ara to stack with it.
