really, you can keep doing the same cycle until you aren't progressing on a cycle this size. Really you could do it for some time but I would suggest trying something else next like EQ 400mg instead of deca. Sometimes its about switching compounds vs just increasing the dose. You can still do everything else the same. Also, look at the diet. Keep educating yourself and make sure you’re always improving the plan. Remember no diet is static. You need to listen to your body and adjust as needed. If you are really pushing and tapped out in training and nutrition, then you could increase some. Remember this is already going to be a bigger cycle for you. Get the most out of it
