Would you care to return to the time when you experienced height increase?

No. I do not reside in the past.

No, because the methods employed to increase your height during puberty often result in more hazardous long-term side effects than limb lengthening. HGH leads to various changes, including a heightened risk of heart disease, diabetes, and even alters your facial appearance. Research the term “acromegaly,” which arises from supra physiological levels of HGH obtained through large doses during puberty, necessary for any meaningful height increase (3-4 inches).

Another medication associated with height enhancement is AIs, which diminish estrogen conversion, thus slowing the growth plate fusion rate. However, this negatively affects bone density and can lead to greater androgen signaling in the brain, potentially heightening aggression and other male traits, including an increased likelihood of developing dementia later in life.

Were I to have the chance to return to when I was 8-9 years old, the time when puberty began and address my growth disorder, then indeed, I certainly would.

HGH may not work effectively on certain patients (specifically those who are at or below -2SD of the average height; otherwise, sensible doctors would not be willing to inject HGH into your bodies) because of factors like insusceptibility to HGH, pre-existing normal HGH levels, early fusion of growth plates, and other reasons.
However, if it could have an effect on me, someone who would prefer Schizophrenia over being short, then the potential side effects such as heart disease, Acromegaly, or diabetes would feel like a mere walk in the park for me.
