only HG peptide boosters that work are injected
repeating: You may be over training, that can trash hormones and you seem weight obsessed on the WWW while trying to grow taller.
To maximize GH feeding response, you need to have some carbs and proteins. The carbs digest, glucose and insulin go up, as glucose is forced into cells and drops, insulin drops, and by that time, you are absorbing amino acids from the gut and serum amino acids are increasing, these factors trigger GH release. Any carb loading at the wrong time can blunt that response. If your glucose levels and insulin are always low, that may interfere with feeding response. If you have the wrong kind of hunger, you will be using amino acids for energy, not growth or GH triggers.
Some trigger GH with amino acids nicely, others not. No way to tell. Glucose/insulin still applies.
Eating every two hours may be time smearing GH feeding response stimuli.
You also need T for long bone growth and you are right in wanting to keep E2 down as that closes the growth plates. Early puberty and rapid early growth typically leads to shorter stature.
Yes some mineral/rock salts contain iodine, but might not be sufficient. Iodine is iodine, it all comes from natural source one way or another unless from a nuke reactor as a fission product.
I would not connect thyroid and glucose levels.
T3 is worrying. Check waking body temps, record and report. Some of the things that you are doing might be interfering with T4–>T3 conversion.
DHEA is low for your age, should be high. We see guys doing things like you who push their cholesterol too low, that messes with steroid hormones. Your DHEA is low and should be high. Eat beef steak, eat eggs, eat cheese, fish oil, nuts and 5-8000iu vit-D3 per day, oil based caps.
Your DHEA and T is low. E2 is somewhere low, but relative to your low T might be some estrogen dominance. T production rates might also be somewhat rate limited by low DHEA levels. Read this:
Your pregnenolone may be low. Test that too.
If you have cholesterol numbers, post them.
I think that your primary focus need to shift to your HPTA and not be height/weight obsessive.
