1 this is a stupid question because we don't know your maintenance
2 all th awnsers have been horrible so far cause they don't know your maintenance
okay now that that's out of the way do you know how many calories it takes you o maintain your weight (not go up or down). Since you have been cutting you should have a decent estimate of when the fat started to come off and maybe add a few hundred cals to that number.
If you know your maintainance calories eating 500 above will give nice lean gains for
more people depending on genetics. When on SD your body will be so great at converting carbs to glycogen and storing it in your muscles for energy along with a huge increase in it's ability to process protein. Sooooooo you can risk eating more if you want in theory some more muscle gains which will come along with fat. 700-800 cals over is alot extra and can build alot of muscle an store some fat. Some go 1000 cals over when on an all out bulk.
Why do you need thr number? Well let's assume you have a slow metabolism since your a former fat boy, and your maintenance is 2600 calories. If you eat 3100 your be 500 aboveand gain nice and steady. Now I'm an ecto and haven't had fat problems, say my maintenance is around 3200 or so. If I eat 3100 cals I would be losing weight very very slowly and not building. If I est 3600 cals or so I build nicely, 4000 I gain a little more fat than I'd like 4500-5000 I gain way to much fat. So you see how if we switch numbers it would be bad for us?
Perfect example being unreal machine has a relatively slow metabolism. Dispite being about 20lb heavier than me with about 30lb more muse mass than I we have around the same caloric intake requirement. So it's based solely on individual.
Now week one will be filled with glyocgen weight gains. Week two is when thr muscle will start flying on so increase cals more in that week along with week three.
Rum SD first. Even though if will shut you down more the epi will allow your body to get used the the mass and make it easy to maintain after pct.
