WHY SHOULD I TAKE ON-CYCLE DEFENSE WHILE ON GEAR?

That's exactly why we created it! We know enhanced athletes put their bodies under additional stress, so we developed a formula specifically with you in mind.

Our goal was simple: bring together carefully selected active ingredients to support the major areas of health that can be affected while on cycle, including your liver, heart, kidneys and cardiovascular system. All in one convenient formula!

CAN THIS REPLACE MY CURRENT CYCLE SUPPORT STACK?

That's the idea! Instead of buying and managing multiple supplements, we've combined 15 active ingredients into one convenient formula.

  • Less hassle
  • Fewer bottles
  • A simpler daily routine

Whether it replaces your entire stack depends on what you're currently taking, but we're confident in what we've created and the value it brings to the table!

WILL THIS PROTECT MY LIVER, KIDNEYS AND CHOLESTEROL WHILE ON CYCLE?

We've specifically selected ingredients for their potential to support liver function, antioxidant defence, cardiovascular health and healthy lipid metabolism.

Our goal is to help you take a proactive approach to your health while enhanced. While no supplement can guarantee protection against the effects of anabolic steroids, we've designed our formula with these key areas in mind.

ARE THE INGREDIENTS ACTUALLY EFFECTIVELY DOSED?

Absolutely, we've put serious thought into our formulation!

We've worked with specialist formulators to fit as much targeted nutritional support as practically possible into one convenient capsule, carefully considering ingredient research, dosages and effectiveness.

We didn't want another supplement with a long ingredient list just for show. Our goal was to create one of the most comprehensive and competitive on-cycle support products on the Australian market.

IS ON-CYCLE DEFENSE ONLY FOR BODYBUILDERS OR CAN TRT USERS TAKE IT TOO?

Definitely not just bodybuilders! Whether you're running a cycle, on TRT, training BJJ or simply serious about your long-term health , we designed On-Cycle Defense with enhanced athletes and active individuals in mind.

You don't need to be a competitive bodybuilder to prioritise your health.

IS ON-CYCLE DEFENSE TESTED AND QUALITY ASSURED?

Absolutely! Quality is something we take seriously.

Our products are formulated in Australia using carefully selected ingredients and manufactured with a strong focus on quality and consistency.

Every batch undergoes careful quality checks to help ensure it meets our standards.

The quality on this bottle is nuts for the price. Even just the feel of it makes it premium. The ingredients inside are dosed great and trust me, I've tried a lot of all in one support. I attached a video for you lads to see

Simon here, been on trt for 20 years and on and off cycles. Ordered fulfilled next day as promised and product just came. Really excited to get started

Ordered 4 bottles as I'm doing a pretty hectic cycle. Haven't found much like this online glad some in Aus is doing it !!

This shit actually works. Got my blood work done and literally better than when I was taking all the other supps. This is a product I'll keep using, even if I am not on trt

Started a month ago, easiest process. Solid ingredients and support from the team is elite.

Keegan (Australia)

Used to be the bloke who'd spend a fortune on protein, pre-workout and everything else but wouldn't give cycle support a second thought. Bit older and wiser now. Found these guys through Instagram and liked that they're actually talking to enhanced lifters instead of pretending everyone is natural. Easy to work into my routine and no dramas with the order.

Darby (Australia)

Been on the gear long enough to know you can't just wing it forever 😂 Good concept, fellas.

J
Aus Pro Nutrition
Jarrah (Australia)

Currently midway through a cycle and a mate sent me the link to this. Had a proper look at what's in it before ordering. Normally pretty picky with supplements but liked the idea behind this one. Obviously still getting bloods done and keeping an eye on everything, but it's convenient having a few ingredients together.

K

Kadel (Australia)

If you're spending hundreds on a cycle, spending a bit on general health support makes sense to me. Pretty simple really.

B

Brodie (Australia)

Been running cycles for years and only recently started taking the health side seriously. Wish I'd thought about it a bit earlier tbh.

H

Heath (Australia)

One of the boys at BJJ mentioned this after training. Hadn't heard of it before, so went home and checked it out. I like that they've kept things pretty straightforward without a million different products. Haven't had it long, but first impressions are solid.

Z

Zane (Australia)

Been following the brand on Insta for a bit. Finally pulled the trigger. So far so good 👍

T

Torrenb (Australia)

At 43 I'm looking at training a bit differently than I did in my twenties. Still love lifting heavy, but I'm paying more attention to the stuff outside the gym now. Came across this while researching cycle support and spent a fair bit of time looking at the ingredients before ordering.

D

Declan (Australia)

Was surprised how quickly it arrived. Packaging looks mint too.

R

Rohan (Australia)

Didn't buy it for any fancy promises. Just wanted something straightforward that fits into my routine. That's exactly what appealed to me.

E
Aus Pro Nutrition
Eamonw (Australia)

Not usually one to leave reviews but thought I'd give these guys a mention. Had a couple of questions before ordering and they actually took the time to explain everything instead of just pushing a sale. Haven't been using it long enough to comment on results, but the customer service was spot on. Nice dealing with a local Aussie business for a change.

Nikos (Australia)

Missus reckons I've got enough supplements to open my own chemist 😂 This one's staying though.

C
Aus Pro Nutrition
Calland (Australia)

Been training for nearly 15 years and I'm definitely more conscious of what I'm putting into my body these days. Used to just focus on the gym side of things and not give much thought to anything else. What caught my attention was the ingredient list and the fact it's designed around people like us. Still early days but happy to have it as part of my routine.

Enhanced or natural

No. You don't need to be enhanced to care about your everyday health.Although On-Cycle Defense was developed with enhanced athletes in mind, its ingredients can also appeal to natural lifters and active adults looking for convenient nutritional support. It doesn't prevent or reverse the potential health risks of anabolic steroids or TRT.
