Nooooob here, but -
Yeah… this is pretty much what I've read GH does when you ramp it hard. I would imagine going quickly to 6 IU is no joke, and it seems like getting there that fast is usually when all these sides shows up. Tingling hands/feet, quick scale weight from water, night sweats, frequent urination, acne — all seem normal GH, not necessarily a sign something is “wrong.”
For what it’s worth, my own experience: I’ve been on GH about a month. I figured I may try it as it could be helpful for healing and while i'm still losing weight. My natural IGF is around 200 with a Z of 0.7, when I got baselines months ago. When I started gh, I began at 2 IU, then played with 3–4 IU in week two. At 3–4 IU I’d get very tired about ~12 hours later, but no other real sides. I backed off, as i'm not in a rush, and I’ll probably experiment again later. I’ve got bloods coming up in a few weeks and I’ll reassess after that. I’ve run tesa/ipa before and that pushed my IGF into the high 300s and a Z of 3.3, so I’m curious where straight GH lands me.
Personally, I wouldn’t try to “push through” 6 IU right now. Dropping back to 2–3 IU, letting things settle, then slowly creeping up may be better. Seems like a lot of people don't really need more than 3–4 IU anyway. But, many more experienced people across this forum, so just my 2c right now.
The way i think about it: GH is slow. It's a boring drug that may pay off over time. I'm already a big and tall dude, and maybe it could have had some interesting effects has I taken it in my teens, but I was miles away from that thought process and I definitely wasn't going to jab myself in those days...shoot I still get nervous pinning anything.
