True sust is a blend with a specific ratio of esters. I doubt if most UGL's pay much attention to that. It was developed to try and get peak levels sooner and last longer but that has proven not to be the case. Test levels tend to be more erratic and, as a result, side effects can also become more of an issue. Hence, you will not see a doctor prescribe Sust for TRT.

Ace or Prop can be used but cypionate and ethanate are recommended because you will require less pinning which is easier for someone starting their first cycle. Split your weekly dose in half. Pin on mondays and thursdays for example.

Save the sust for a later cycle.

Get bloodwork done before your cycle to establish a baseline.
Make sure you have everything you need and then some. Includes AAS, PCT, and ancillaries (syringes, needles, swabs, blood pressure monitor, calipers, etc. etc.).
Have a goal and stick to it.
Have a clear calendar.
Have a menu plan and stick to it.
Have a workout schedule and stick to it.
6 weeks in, get blood work done.
near the end of your PCT, get bloodwork done.

You should not be cavalier about what you are about to do. Plan it out with the seriousness of planning a backpack trip for the appalachian trail. Every detail needs to be thought out and planned as if your life depended on it. A little dramatic perhaps but the success of your cycle will be in the details, not the gear.
