If you look at bodybuilders from the 1960s–70s and compare them to today’s “superhuman” physiques, you might wonder: are we even talking about the same sport? Many experts point to two hormones that changed the game — HGH and IGF-1. HGH entered athletes’ regimens in the 1980s, and IGF-1 became more widely discussed and used in the 2000s. But what does each actually do, and when does one make more sense than the other?
I published a detailed breakdown that explains, in plain terms:
It’s not just about muscle — the article also covers connective-tissue repair, joint comfort, and recovery. If you want the full picture (mechanisms + usable protocols), check it out:
GH and IGF-1
Curious what others have seen in practice — particularly for tendon/joint recovery while on GH. Thoughts?
I published a detailed breakdown that explains, in plain terms:
- Why HGH is the upstream “master” hormone while IGF-1 is the tissue-level executor
- How exogenous use of each differs—especially for glucose control and insulin sensitivity
- Why HGH alone can worsen insulin resistance, and how IGF-1 can offset that effect
- Clinical evidence showing GH + IGF-1 often produce better protein anabolism and fat oxidation than either alone
- Practical protocols for bodybuilding, recomposition, and long-term HRT/anti-aging
