I too took a regular dose of 2 IU of script HGH for years. Anyone who says it does not change your physique, I would argue strongly. Does it change it drastically like it does with high dose HGH and another compound to control your blood sugar - no.
What is your goal for jumping on the HGH? Growth/bulk, longevity/anti-aging, healing injuries, etc.?
A 2 IU dose is more about longevity, anti-aging, but there is no question it will increase your ability to heal quicker. I could hit weights and then hit the heavy bag or spar for an hour after without fear of overdoing it - ending in an injury or strain.
The stuff was like magic. I used Serostim, some Huma, and Geno's.
For 2 IU, I would dose it based on how it impacts your sleep. For guys like
@3ml, it fucks his sleep up and it really messes up my sleep as well so I took it in the AM hoping this would help. My 'coach' - I don't compete but a top level Canadian bodybuilding friend on the forums and in real life, wanted me to take it at night for the sleep/healing/anti-aging benefits because he knew my goals were not to get massive or compete.
The main point with 2IU's (still monitor your BS to ensure you don't have issues, which you most likely won't) is just get it into you daily or whatever protocol you are going to run such as 5 days on/2 days off or like I did 365 days a year.
I am convinced over time it changed my 'normal weight' if I never lifted weights and did not eat to grow. Best guess I would be 205 if I never touched weights and ate 3 decent meals a day. After taking HGH and TRT for a few years, I noticed it was almost impossible to get below 215. This became the weight I sat at when I was taking months off for personal reasons, injured, etc.
I also found it helped bulk, and it made no difference when I took it - AM or PM. If I was using for a different purpose, I would have taken it multiple times a day with another compound, but I was not willing to go down that road.
Did you get UGL or script HGH?
Even though you may never have a blood sugar issue, please make an effort to keep an eye on it regardless of how low your dose is. I did 1-3 IU at different times and my BS was fine, but everyone is different.
Best of luck.
