If you decide to cycle, 250mg of tesosterone per week will be a good starting point. When doing a low dose cycle the following things are important:
1. Use either Cypionate or Enanthate (long lasting esters of testosterone), stay away from sustanon for low dose cycles.
2. This is your first cycle--if you do not eat well, then don't blame your lack of growth on your gear or the dose. Too many newbies (and some on their 2nd or 3rd cycles) don't gain as much as they hoped on their first cycle, then they blame gear or dose. Don't fall into this trap.
3. Make sure you are disciplined consistent in your nutrition, sleep and workout intensity. Don't think you're magically going to start doing everything right once you start your cycle. Don't start your cycle until you have gotten through at least 2 months of diciplined balanced nutrition, rest and workout intensity.
4. Perfect your diet before you start your cycle.
5. Perfect your diet before you start your cycle.
6. Perfect your diet before you start your cycle.
(Did you get the point?)
If you have all your ducks in a row, you can gain 10-15 lbs on a low dose cycle.
Make sure you take note of how your body reacts to the testosterone (i.e. when it starts to take effect in YOUR body, how it affects YOUR gains, how it affects YOUR mood, etc.) Many people have stories about how AS (Anabolic Steroids) work, but AS affects everyone differently. So, the only way to know how you will be affected is to use it and take note of the effects.
If you haven't already, do a search on this board using the phrase "low dose," and you'll find a ton information. You can also search by my screen name BASK8KACE--I've written several posts on low doses. The search key is in the far upper right corner of this page.
Lift hard, eat well, rest reasonably and grow.
Best of luck to you.
