They all seem to lose the effects if you don't cycle.
My fav test boosters ingredients are high dosed Fenugreek, DAA, 3,4Divanil, LCLT, L-Dopa and Androst-3,5-dien-7,17-dione.
You can find these ingredients in,
TitaniumXL
Formula-X
Division 1
Erase
HGHUP, Powerfull or Endosurge.
I also like to get on topical dhea once or twice a year for 6-8 weeks, Transderm or Dermacrine work wonders for me, it's in the pro hormone class, but I consider it semi natty lol
