JING is SuperFeast's most revered formula, a blend of the most time-honoured Jing-building herbs in the Taoist tradition, with a cult following that has built steadily since we launched it. It's the formula for people dealing with deep depletion, fatigue, hormonal dysregulation, and the kind of structural and constitutional exhaustion that takes years to build and years to genuinely address.

It's also, increasingly, a formula that competitive athletes are working with, people whose relationship with their supplements carries a layer of accountability that most consumers don't have to think about. A positive test for a prohibited substance can end a career, regardless of whether the contamination was intentional.

That's why we got our JING blend HASTA certified. The only independent certification for WADA banned substance testing available in Australia. And the story behind that decision says something about how we approach quality that's worth telling properly.

What Is HASTA Certification?

HASTA, Human and Supplement Testing Australia, is the Australian sports supplement drug testing specialist, a division of Racing Analytical Services Limited, Australia's largest independent sports drug testing laboratory. 

HASTA is the only laboratory in Australia able to provide independent certification of sports supplements by testing for WADA prohibited substances. WADA, the World Anti-Doping Agency, publishes a list of prohibited substances and methods annually. HASTA's comprehensive sports supplement screening test covers over 250 WADA prohibited substances, using the NATA accredited testing method and developed specifically for the Australian market. 

For competitive athletes, from weekend warriors to elite professionals, a positive test for a banned substance can mean a suspension of up to four years, regardless of whether the contamination was intentional. The supplement industry's contamination problem is not theoretical. 

In 2022, Sport Integrity Australia commissioned HASTA to purchase and analyse 200 sports supplement products available online in Australia. Of the 200 products tested, 35%, around one in three, were found to contain one or more WADA prohibited substances. In 57% of those tainted products, the banned substances did not appear anywhere on the packaging or product website. 

One in three supplements. Contaminated. No disclosure. Athletic careers at risk. 

The Difference Between Batch Testing and HASTA Certification

This distinction is important. Batch testing means a specific batch of product has been sent for independent third-party testing. It is a meaningful step beyond no testing at all. But it is not certification.

HASTA certified means every batch is tested for WADA banned substances. But certifying a product involves not just testing, it also requires verification of the manufacturing quality controls that are in place. HASTA certified requires significant additional commitment from the supplier, including verification testing of multiple samples from different batches. 

Certification is ongoing accountability, not a one-time check. Every batch of HASTA certified JING (powder and capsules) is independently tested before it is released for sale. The batch has been tested, by an independent laboratory, against over 250 prohibited substances, before you purchased it. All batch testing is shown on the official HASTA website and we also provide the laboratory testing certificates if you would also like to view it (email us to request team@superfeast.com.au). 

Why JING Specifically

The decision to pursue HASTA certification for JING wasn’t an arbitrary decision. It reflects where the product sits in our range and who is working with it.

JING is a deep Jing tonic, a formula for the constitutional layer of the body, for the reserves that govern structural integrity, hormonal function, reproductive capacity, and the fundamental vitality that sustains everything else. It contains cordyceps mushroom (CS-4), eucommia bark, cistanche stem, goji berry, rehmannia root, asparagus root. In the Taoist framework, Jing is the root. When it is depleted, every other system is compromised. When it is nourished and built, the body's capacity improves.

This is precisely the terrain that athletes should address. The demands of sustained high performance, the training loads, the competition stress, the chronic physical demand on the body's structural resources, deplete Jing. The herbs in JING were selected specifically for their capacity to address this kind of deep constitutional depletion: eucommia for structural integrity and Kidney Yang, rehmannia for Kidney Yin and Jing restoration, cistanche for the deeper Yang reserves that sustain physical vitality across a demanding life.

Athletes and coaches who understand tonic herbalism are increasingly working with JING for exactly this reason, not just for acute performance enhancement that the sports supplement industry typically markets but for the longer-term constitutional support that genuine resilience requires. These are people who need to know that what they are taking is clean. HASTA certification gives them that assurance in the most rigorous form available in Australia.

What It Says About Our Standards More Broadly

HASTA certification for JING is not an isolated quality decision. It is an expression of a broader commitment that runs through everything we do.

The Di Dao sourcing that traces every herb in our range to its authentic native growing region. The HPTLC testing that verifies botanical identity and plant part on every batch. The TGA listing that confirms our products meet Australia's therapeutic goods manufacturing standards. HASTA certification sits within this framework, another layer of analytical accountability that goes considerably beyond what the supplement market typically provides.

No product testing can ever guarantee that a batch is completely free from contamination. We are clear-eyed about this. Certification is not a guarantee of perfection. It is a commitment to a standard of independent verification that we are investing in. 

The athletes, coaches, and practitioners who work with JING deserve to know that the formula they are trusting with their performance, their career, and their health has been independently verified by the most rigorous testing available in Australia. It is a straightforward obligation, and it is why every batch of JING powder and capsules carries the HASTA certification.

The Data and the Bigger Picture

The supplement contamination data is something to think about. One in three products tested by Sport Integrity Australia contained banned substances. More than half of those did not disclose it. These were not obscure black-market products, they were the kind of supplements available from mainstream Australian retailers.

In this context, HASTA certification is not a luxury or a competitive differentiator. It is the minimum standard athletes require. 

JING is a formula for the long game. For the deep constitutional work that takes months and years to produce its full expression. The people who commit to that kind of practice deserve a product that has been held to the same standard of rigour, tested, verified, accountable, and worthy of the trust they are placing in it.

Frequently Asked Questions

Q: What is HASTA certification?

A: HASTA, Human and Supplement Testing Australia, is the only laboratory in Australia that provides independent certification of sports supplements by testing for WADA prohibited substances. HASTA certification means every batch of a product has been independently tested against over 250 prohibited substances before it's released for sale, and that the manufacturing quality controls have been verified. It's the most rigorous supplement safety certification available in Australia.

Q: Why does HASTA certification matter for athletes?

A: A positive test for a WADA prohibited substance can mean a suspension of up to four years, regardless of whether the contamination was intentional. In 2022, Sport Integrity Australia found that one in three supplements available from mainstream Australian retailers contained WADA banned substances, and more than half didn't disclose it anywhere on the packaging. HASTA certification means the product has been independently verified as free from prohibited substances before it reaches the athlete.

Q: What's the difference between batch testing and HASTA certification?

A: Batch testing means a specific batch has been sent for third-party testing — meaningful, but not the same as certification. HASTA certification requires every batch to be tested before release, verification of manufacturing quality controls, and testing of multiple samples from different batches. It's ongoing accountability rather than a one-time check.

Q: Is JING only for athletes?

A: No. JING is a deep constitutional tonic designed for anyone dealing with depletion, fatigue, hormonal dysregulation, or the accumulated stress of a demanding life, athlete or not. HASTA certification is relevant beyond the athletic context too, it means the product has been independently verified for purity to a standard that the mainstream supplement market rarely meets. 

Q: Can I see the HASTA testing results for JING?

A: Yes. All batch testing is publicly listed on the official HASTA website. SuperFeast also provides laboratory testing certificates on request; email team@superfeast.com.au.
