I'm a strong believer at 'if you don't try it you can't know'. All the theory in the world won't have you ready 100% for a cycle.My advices are:

-Pin every Monday and Thursday (for enanthate)
-When the first sign of gyno arises (if it arises) take aromasin ASAP to lower estrogen.
-Count your calories as well as possible and unless you are an octamorph don't eat TOO MUCH.
-Have a solid pct plan which is not a hard thing to do at all and remember that being on cycle is the easy part,not loosing your gains after it is what's HARD.


Half-life is the difference:
Testosterone Cypionate 12 days
Testosterone Enanthate 10.5 days*
Testosterone Propionate 4.5 days

Enanthate and cypionate need only 2 injections a week to keep the blood level steady.
Propianate needs ED (every day) injections or EOD (every other day) injections to keep the blood level steady.

Steady blood level means less sideffects.
