It's safe to assert when administering high doses of gear, it would be a wise move to get blood work done every 3-4months if you can.
Some have more tolerance to drugs than others, but nonetheless, drugs will affect you.
...on a side note, one thing i learned since i started AAS, it's best to try things out for yourself and arrive at your own conclusions.
Reading forums and asking experienced members is a definite positive, but even then , without personal experience, it's meaningless.
...and personal experience is uniquely individual, that's why you get opposing viewpoints, like in this thread.
I also noticed that a good portion of veteran forum members lie through their teeth.
They would be dishing out insults and giving you advice they themselves heaven't followed in years, if ever.
So take what you read with a gigantic grain of salt.
