In a cycle you "kick started" with dbol....

[Meso_z]

Will you lose the gains dbol gave you? assuming you continue with your deca/test.

[Rimbaud]

You shouldn't lose too much if anything. If you start with six weeks of dbol by the time you stop you should be cruising on the Test & whatever else you're taking. Remember though whenever you stop a cycle you always lose something.

Also remember some of what you gain from the dbol will be water. This can work to an advantage while ON though as the extra water weight will give you more leverage to move heavier weight which will aid in growth. You will lose the water when the cycle ends.
