Hello, in fact, if there would be a cycle that you can run indefinitely and a cycle that would make you feel better that's TRT with HGH.
A lot of people, actually, run TRT + HGH. And they do great!
yes, 2-4 IU would have noticeable effect. you can be sure about that. Running it for 3-4 months is "sad". Definitely won't be useless because you're still going to see results at that dosage used for that period. That's "sad" because you will most likely love how you feel, and you'll need to give up on HGH.
about 4 IU is required to notice lean muscle mass growth. Doses 2-4 IU are great for energy, motivation and overall health! no worries!
just make sure you don't have any cancerous cells before starting HGH.
but then again, generally TRT + HGH is what most people run indefinitely and they receive amazing health benefits. PS: I know methods to get lower priced HGH (because indeed, HGH can be EXTREMELY expensive).
