Depends on many factors. Age, experience, quality of the item being used, which item. Are you meaning Hormones or Anabolic Steroids
You see some hormones like Test Propianate for eg is fast acting thus is fast leaving thus need to be injected almost daily, test cypionate longer lasting slower acting, or you get a blended product like in Australia we have SPECTRIOL which is a blend of many testosterones but is weak as piss IMO, so that means you need to stack "this and that" to get the desired effect and then you need to cycle correctly or risk being left with the testosterone level of a 65 yr old woman so you need proper PCT (post cycle treatment) CONFUSED good stay away from drugs, for now anyway "live and learn, not crash and burn"
The quick answer is study, and earn your stripes before you play with Hormones |
