23 isn't dangerously too young for a short course of var... I find var starts to suppress my natural test around 3 weeks into the cycle, and therefore, when taken without test, it produces the best results for the first 3 weeks of a cycle... And after 3 weeks I start feeling like a shitty little girl.
If I had to do anything at your age, and believe me, I did var at your age, I would consider 2 short cycles rather than 1 longer one, taken 2 months apart. For the record though, my natural test levels were borderline deficient through my 20's, YMMV. Doing a "PCT" without a cycle (hcg, hcgenerate, clomid) did more for my gains than taking the var did due to my issues with endogenous test.
40 or 50mg split into 2 doses per day, taken sublingually, provides the best results... Especially when loaded with creatine monohydrate (10g for the first week, 5g for the next 3) using an OTC PCT like any of the need2 products or simply formestane.
But if you're just trying to cut, I'd consider a drastic diet before AAS... Save your first cycle for a clean bulk AFTER you cut or something. Count your calories, consider an ECA stack as others have said, look into keto (did wonders for cutting) and keep lifting heavy... You'll be surprised what you can do. That way, in around a year when you're cut as you'd like to be, start pinning some test, use your var, and you'll get much better results.
