i agree dbol only cycle is fine.
I would go 4 weeks or just slightly less .. do not exceed that unless you want to run a heavier PCT.
20mg per day, if you can handle the sides go 30mg. keep AI on hand if/when you bloat like a fish though. and run liver support of course
if you keep the cycle under 4 weeks then unleashed/post cycle taken for 1 month would be enough.
if you go longer though you will need to get stronger PCT so keep it 4 weeks
