It's individual brother. 200mg is a HRT replacement dosage for some people due to how their bodies metabolise the hormone or if they have higher bodyweights (pro bbers).
Its not worth shutting down your natural production to use 200mg. I would stick with 500mg per week to see how you tolerate it, and have anti estrogen meds on hand in case you are a high aromatiser.
- 12-16 week cycle
- Full blood tests before you start
- Full bloods again about 6 weeks in (on the day you're due to inject, but before you dose your testosterone) to get a trough level
- Bloods at the end of your cycle to see how your health markers are (liver, kidney, cholesterol etc).
- Anti estrogen meds on hand BEFORE you start, instead of scrambling to order them if you get symptoms
- You need to decide if you want to PCT after, or just drop down to a cruise dose if you plan to do more cycles
I'm assuming your nutrition, training and recovery are all dialled in?
