Letro lowers your sex drive (libido) for the first 3 months. You'd still fap tho haha. Might even be good for nofap. It's not permanent at all, and I'm still on it and have my original sex drive pre-Letrozole already. Would be healed if I came off and tapered safely off it. No harm, wasn't an issue to be honest.
GH gave me water weight during the time I was using it. I'm talking about 7-10 pounds of water weight, much on your face. It's not really a big deal, especially if you're a skinnier person. If you're normal weight, it's not that bad, sure you'd look better if you didn't have this water weight, but honestly you take and you give if you want to grow. A little bit less comfortably for an inch while I can still grow? No doubt I'll do it.
GH also made me hungry- like crazy hungry that I would need to eat alot. Not a big deal, go less on the carbs though, you'll find yourself hungry often. It did elevate my blood sugar a tad, but when I stopped GH it went back to normal pre-GH levels. I did use a glucometer to check often. Try to avoid binge eating.
I'm still on letro, but stopped GH since January this year. I stopped because I was feeling more confident, and I don't regret stopping either. I'm probably almost done with my growth anyways, I got an inch and that was worth everything.
After stopping GH, I lost like 8 pounds of water weight within 3 days. Felt great to see my face less puffy with water. No side effects.
If your bone age is 17.5, you could probably squeeze in 2cm. It's near the end, but honestly don't worry too much. First of all height neurosis won't kill you. LL is always available, and with Stryde and and the tech coming up, it's becoming less taboo to do LL and honestly just feels like if you got plastic surgery on your face. Not really, but still, I'm hyped on the future progress with LL. Stryde literally is revolutionizing. Let's get to our goal heights, and honestly life still goes on regardless.
