With hgh you are better off using a low dose for a long period than a big dose for a short period IMO. For most of us that are not rich, we are looking for bang for the buck! IMO the best way to get that with hgh is to use it in conjunction with harsh aas. For example test, tren, dbol, hgh and slin are a favorite cycle of mine.
Obviously if you are asking which is better if the time frame is the same, the higher dose is!
I hope that answers your question.
