The half life is roughly 190hrs of T4 , the serum concentration builds as you take it. Each individual has a different need . I started at 25mcg and have used up to 200mcg depending on how much gh I’m using and my TSH . I like to keep my TSH to stay low. I’ve had so many bloods done over the years that I know how to dose it . Kinda like when your TRT levels need adjusting . After you take it Once daily (I don’t eat for 45-60min) but I’m usually doing cardio anyway and drinking 2 servings of black cold brew coffee diluted with water . It wakes me up and I notified a nice improvement on my gh utilization. I progressively have gained more lean mass each year. If you are going to compete , it’s good to know how to utilize both t4 and t3 as they both work differently : T3 , I only use pre-contest or photoshoots and I taper off slowly .
Now that I am on HRT(test/gh) for life , my HRT dose of T4 is only 50mcg. The higher my mg/IU dose goes up, the more T4 I need to keep me at my comfort level (.44) is where I am at last bloods. My MD years ago said that I have a normal size thyroid but that it was hyper functioning . I don’t have hyperthyroidism at all but, it explained why as a child until now I’ve been able to just eat insane amounts of food without getting fat (even before I started TRT and TRT/Gh) .
Taking one bigger dose of GH worked for my last experiment . I used 10iu mon-wed-Fri and (sermorelin forte plus/ghrp6/ghrp2 ) Tue, Thur, Sat,Sun. . It was highly successful.
I’ll be using it daily starting Monday (hence why I am training late close to my bedtime). Then T4 100-200mcg when I wake .
One other experiment I want to try is taking MK-677(Ibutamoren Mesylate) and GH as I’ve kept coming across multiple BB and research papers that show they work synergistically and not how I imagined years ago. I used to take gh 4 days and MK-677 the other 3 days because I figured - GH is exogenously raising my gh/igf-1
and MK677 causes the body to endogenously produce higher gh & Igf1. It still worked well
….
Next year when I run another bulk blast I want to take them both daily. This will be my protocol (next year): gh spilt dose (am fasted and post workout) and then the 25mg mk-677 before bed. Maybe someone who reads this can run it for me before I get to ?? It should keep a persons Igf-1 higher for longer than any gh protocol alone . (T4 is a given also)
Even guys on TRT or oxandrolone Trt or Nandrolone TRT should get a thyroid panel as testosterone and derivatives can raise tsh enough that it is becoming common for centers to Rx Levo T4 with Testosterone (especially in long time hormone users.
