There are lots of tall claims about gh. People say it melts fat, miraculous gains, etc. It's not that miraculous. But if you can afford it, it's worth it. Over a long term period of use (at least 6+ months solid use) it will lead to a leaner midsection. Especially in older guys. But 3 months of gh is not going to do much for fat, it doesn't melt fat. You're better of with clen and t3 for that.
I'm no GH expert but I've run rips before for long periods and now I've run legit pharma norditropin for 7 months now, 6 days a week. I still think gh's biggest attribute is recovery and connective tissue. The one visible difference you will see is it absolutely does help keep your midsection leaner in a calorie surplus or bulk phase. This may actually be more valuable than using it for a cutting phase because as I said, it doesn't rapidly melt fat like people hype it. That is all I can say definitively from my experience. You can be a little lazier with diet. Over longterm use, it does give the muscle a fuller more vascular look as well. But AAS is still the work horse for raw gains.
This may all change at 6-8 iu of pharma gh but I only go up to 4iu a day. I don't even compete. I see a lot of hype about gh that seems blown out of proportion. It's not going to change your physique overnight. If it breaks your budget and you have a family to feed, don't do it. Clean diet and AAS is all you need.
