My question
I planned on doing a var only cycle this time around because I don't want to gain too much weight, and I don't care if my dick doesn't work for 8 weeks. so please don't bombard me with "Test Base BRO" or the like.
Now that that is out of the way,

1 )I was thinking should I start this cycle with 50mg for weeks 1-2 then for weeks 3-8 use 75mg, or should I use 75mg or 50 mg throughout the entirety?
----What dosage and time would you do? I've read conflicting reports saying 7 weeks is the sweet spot, but then I've also read that 75mg is the sweet spot.
2) Should I cycle my calories? For example I was planning on doing +500 for the first 2 weeks, then bump it up to +1000 then finish it off during weeks 7-8 with 2100 to really cut the fat off.
---- Or should i just go big in the beginning and hit +1000 or +500 for the entirety?
3) Does that diet make any sense?
---- I just dont understand how people are eating at maintenance yet gaining muscle and losing fat, I've been natural up to this point so this idea is confusing to me. Any info would be greatly appreciated.
4) I have slightly high BP currently (120/85) And have been prescirbed Lisinopril 2.5mg, I have enough to cover me throughout the cycle at a dose of 5-7.5mg ED. Would that be a good idea? That is the only reason I wanted to start with 50mg instead of 75mg, to get a feel for the var.
5) I also have finesteride 1mg but dont use it at all (Ive come to terms with my hairloss) But I have also read that anavar doesnt affect hairline at all, so this will just be backup i guess
6) I have slight slight slight gyno ( I think, self diagnosed) Anavar isnt supposed to do anything regsarding that right?

Thanks
