my mates dad runs 6 months on and 6 off he been doing it now for 10 years he always uses sust at 250mg shot every 7 days but his supplier has ran out of sust and can only get cyp.
questions.
if he uses the cyp this time would it take longer to kick in then the sust would?
would he notice the difference from using the sust to the cyp? as with sust having prop in it it should kick in quicker but as he his shooting every 7 days will he even be geting much out of the prop?
