No there is no substitute for injectable GH. All the OTC "gh boosters" are a waste of money. I'd stay far far away from them. If funding a GH cycle is the issue, you can get some results using the research peptide secretagogues, such as GHRP6, GHRP2, CJC and IGF-LR3. Using these in combo can be cheaper than using GH and can give results. Or using them with a lower dose of GH can be beneficial.
