I don’t know how long Kad was running for and how much he was running but 4 months isn’t long enough to really notice any significant physiological changes. I don’t care if it’s Pharma grade, hgh takes more time than that. Unless you’re running like 6 to 10iu a day then you might start seeing something around that time but otherwise its superficial stuff like better sleep, better skin, better nails, maybe some belly fat loss but nothing otherwise
