Well search around the online shops to see what you can see but BPS Androcrine is getting good reviews (transdermal Laxogenin) you can mix that with OL Ep1c Unleashed (oral Epicat)
Follidrone 2.0 is an oral myo inhibitor, among other things, that has received good reviews on here.
Another option is SNS XGels and OL Tr1umph.
All of these are natty options that require no PCT so if you can find a way to get any of the combos to you Down Under you'll be GTG.
Whatever you decide to run try to go 8 weeks with and really keep your diet and training on point for best results because these options are not as powerful as PHs.
Some good options in here.
Follidrone 2.0 is getting very good reviews, and a few people really enjoyed stacking it with AlphaMax XT (a natty test booster that can help with strength, body composition, mood, and libido). Testify is another good natty test booster as well.
OP, if you aren't already taking some daily "staples" like creatine and betaine, you could benefit from using a daily supplement like PowerMax XT, Ergonine, or Triumph. These don't need to be cycled, but are a good natural base.
Of course, don't expect the same level of gains with natural products as with PHs/gear, but you aren't messing with your hormones, and don't need PCT.
