Rhgh/somatropin has been used for several decades to help patients gain height by increasing the bone mineral density and overall bone mass. However, its effects on increasing height can be variable due to the involvement of various factors, such as IGF-1 and its responsive bone-age, timing, dosage, and duration of use. I will prove below that hgh does increase height.
1. How does high hgh aid in increasing height?
Hgh instructs the liver and the growth plate cells locally to produce IGF-1. IGF-1 is the factor responsible for driving the proliferation and hypertrophy of chondrocytes in the growth plates, facilitating longitudinal bone growth (height increase) at the epiphyseal plates, provided that the plates are still open.
For individuals with appropriate GH sensitivity, the stimulation of hgh suffices to raised IGF-1 levels and boost height velocity.
However, this is not true for patients with Laron syndrome (GH insensitivity) as they can possess extremely high levels of growth hormone but their IGF-1 remains low due to an extremely poor response. Such individuals can only gain from direct IGF-1 treatment.
While synthetic direct IGF-1 injections do not have the same limitations as the liver IGF-1 synthesis, they do come with health risks, such as hypoglycemia, cardiac hypertrophy, and other problems. Therefore, hGH injections remain the primary treatment for peripheral and central IGF-1 production.
2. Evidence regarding height improvements
The numerous systematic reviews and meta-analyses conducted in children with ISS (Idiopathic Short Stature, children with normal gh levels that remain short), have shown clear positive results for gh therapy.
hGH therapy increases short-term growth velocity by approximately 2.86 cm/year in comparison to the control group.
Tthe results of long-term hGH treatment shows increases of 4-7 cm (range of 2-9 cm) to the height of the individual when compared to untreated or expected height. There are also improvements in height standard deviation score (SDS) by 0.6-1.4 SD.
GAINS ARE INCREDIBLY DEPENDENT ON DOSE AND TIME ON TREATMENT. AND THE SOONER, THE BETTER!
3. Relevant Details and Frequently Asked Questions
Although rhGH raises IGF-1 and produces rapid initial growth, it may result in a slight acceleration of bone age and maturation. In most studies, however, linear growth velocity outstrips bone age velocity, and most subjects experience net positive gains in predicted and final adult height rather than merely accelerates maturation.
Children of Idiopathic Short Stature (ISS) have been studied in regards to growth hormone (GH) therapy and its effects on growth velocity and bone age. In recent studies, short-acting GH therapy in this population was the only therapy that had a significant increase in growth velocity with no increase in bone age.
It is well documented that chondrocytes have a limited number of divisions and that natural ossification occurs. While it is true that rhGH accelerates growth during the period of maximal growth potential, it does not eliminate the effects of growth diluting genetics. Most protocols aim to utilize as much of the potential growth as possible prior to growth plate closure.
To mitigate the effects of maturation and extend the duration of the growth plate closure, a number of protocols have combined the use of rhGH with low dose aromatase inhibitors of the type of exemestane, anastrozole, and letrozole to achieve a controlled utilization of estrogen. This has been documented in the literature clinically and in the realm of advanced users.
Bone vs. height. rhGH has a documented history of increasing bone strength along with its density, and this is true even after the closure of the growth plates. Height, however, requires the presence of active, open growth plates.
Studies
Paltoglou et al. (2020): Systematic review and meta-analysis confirming rhGH shows short-term improvement in linear growth and adult height in idiopathic short stature, achieving ~5.3 cm height gain in males and ~4.7 cm in females compared to control.
Deodati & Cianfarani (2011): Systematic review of randomized trials; treated children achieved ~0.65 SD (~4 cm) more adult height compared to controls.
Rahmati et al. (2017): Adult height gained more than 1.4 SD (~7.6 cm) after rhGH, adult height shifted from ~5th to ~54th percentile.
Finkelstein et al. (2002): Meta-analysis of controlled and uncontrolled trials; with rhGH treatment in idiopathic short stature, adult height gain of ~4–6 cm (range 2.3–8.7 cm).
Hintz et al. (1999): Long-term study in NEJM; rhGH treatment resulted in increase in adult height SDS from -2.7 to -1.4, with boys and girls achieving +5.0 cm and +5.9 cm above the predicted height respectively.
Yang et al. (2025): Meta-analysis confirming short-acting GH improves growth rate significantly in idiopathic short stature with minimal effect on bone age.
I have seen many threads pop up recently "disproving hgh" so bcuz im on spring break and I don't have a job I figured I would disprove all of the retards. If you could rep me cuz my ratio is horrible right now that would be great.
