I have been ready to begin regularly using gh for some time now but have not felt confident in what to purchase. I see alot of cheaper blue tops and green tops as opposed to brand name like hygetropin or recently eurotropin. My question is, are there significant differences in the results I would acquire from hygetropin or spectrum pharma as compared to simply blue tops or green top gh. I want what will produce best results for least money obviously but donot want to compromise health also. This is my first post so any advice would be greatly appreciated!
