But why have you chosen to use hgh over something else? Hgh is really the least bang for the bucks you will find. A $60 vial of test 400mg will probably give you better results than $600 worth of gh. Imo the most pronouced effect of gh is the cts, not a good thing. I don't know where you buying the gh but also a good chance is not actually gh. It's easy to make a combination of peptides that will give you higher HGH serum levels, even elevated igf levels so you will think it's gh. Also the side effects of using gh you didn't mention...intestinal/irregular growth from elevated igf levels, using the t4 can cause thyroid Shut down, possibly permanently. You want better eyesight? Go to an eye doctor. Better sleep? I sleep great to begin even on tren so didn't notice any difference , maybe it's just me. As far as increased energy and libido I've never even heard of those benefits myself and I have not experienced them ,maybe some do I don't know? Go back to the drawing board, do a lot more research, decide what it is you want to get from this
