I'm doing test 325 and npp 100 and I've been injecting every 3 days. someone told me I should be injecting every 2 days but I dont know if it's true. If this is true does 1 day really make that much of a difference?
well, if my memory serves, test 325 is basically sustanon, so one would typically inject 2x a week, whereas NPP is typically injected EOD…
Cyco is correct.
