it will raise a lot for weeks, Maineguy...I would think you would know this being on TRT yourself (from what I gather on your comments?).
Have you ever checked your BW doing testosterone enanthate 500mg/week. It keeps climbing for WEEKS.
For me testosterone enanthate levels kept raising until about 3 months on and finally leveled
This means your level after week 1's dose =250mg inside body, however by week 12 you will have a LOT more tren than 250mg!!!!
After 8 weeks of tren e I could no longer handle the side effects and had to stop.
Sometimes reading this forum just makes me cringe. Maineguy, as a curiosity, in 6 more weeks of being on I'd like to hear what you think if 400mg of tren enanthate is "no big deal" or if you have suffered from psychological/physiological damage.
Be careful guys. You only have one run through with this - no "start overs" with your endocrine system.
