With a higher dose I've found it harder to bulk (seem to need more calories), harder to sleep and my skin gets more oily (more spots) also more suppressed, cycle obviously becomes more expensive, and no noticeable increase in results... therefore in future I'll be ruNning low/moderate dosages of test stacked with other compounds....that said everyone is different, no one can tell you what the difference in dosages will do for YOU, you may find there's more gains and no more side effects, or more side effects and no more gains.... there's only one way to find that out....
