My aching back

Started GH 2 weeks ago. First week 2iu's 5 0n 2 off with no problems. Week 2 increased to 4iu's 5 0n 2 0ff. After 4th day this my lower back is killing me. Should I go back to 2iu's? Will I get used to it and eventually be able to increase to 4iu's? Also feeling very tired . And suggestions or experiences.

Peace

I don't think there is any connection there. Probably timing is coincidental. I am a chiropractor and Hgh user if it helps!
