Yes, but the benefits are proportional to how low you were. So may not be the change that others see. Your IGF-1 response is really up to your liver and that varies from one to the other.
1.5 units would get me to IGF-1=330, I have a plot of my dose=response from a few years ago, very linear. Based on that chart, my pre HGH IGF-1 level shows that I was making .4iu/day on my own. If you were to respond the same, your current production would be 0.81iu/day. So you can see how your taking 1iu/day would be only .2iu of increased benefit. So you have to go to quite high IGF-1 levels to get any relative benefit. Can you get Rx for 1.5iu/day, 0.5mg/day?
