You cant run anavar only. Soon your natty testproduction will be much less and soon the sides from that will overcome the gains you got from anavar.
At least you need a trtdose along with it. I tried the sarm rad140 (the socalled trtrsubstitute) my self and it work well with other supressive sarms, but when i introduced an oral aas, it just didnt cut it. It was superdrol, but even if var is much more weak i doubt rad140 would do the job. But im not sure. I used only 10 mg ed and if you jump it up to 20 mg ed, it migth work.

But if fatloss is you main goal and you dont want to put your health at any risk, you should look into SR9009 and/or Cardarine.
They have no sides and are just as effective as any aas for fatburning.

For your little cycle you dont need nolva, unless you are gynosensitive. 4 weeks clomid 100 50 50 50 should do the trick.

Yeah, you can try austs fat loss protocol added Cardarine or SR9009 or both if your real serious.
