Creatine vs. Turkesterone: 30 Years of Evidence vs. Hype

Turkesterone became one of the most talked-about supplements in the fitness industry around 2021, driven primarily by social media influencers and supplement companies positioning it as a "natural anabolic." Monthly search volume surged, and products appeared at premium prices ($40 to $70 per month). Creatine, which has been available for three decades at a fraction of the cost, continued to be the most studied and validated supplement in the category. This comparison is not merely about two supplements. It is about the difference between evidence-based supplementation and hype-driven purchasing.

What Turkesterone Is

Turkesterone is an ecdysteroid, a class of steroid hormones found in insects, some plants, and certain fungi. In insects, ecdysteroids regulate molting. The plant source most commonly cited for turkesterone supplements is Ajuga turkestanica, native to Central Asia. Ecdysteroids share structural similarities with androgens, which is the basis for the "natural anabolic" marketing.

The proposed mechanism is that turkesterone activates estrogen receptor beta (ER-beta) rather than androgen receptors, potentially stimulating muscle protein synthesis without the hormonal side effects associated with androgenic compounds. Some in-vitro and animal studies have shown that ecdysteroids can stimulate protein synthesis in cell cultures and increase growth in certain insect and rodent models.

What Creatine Is

Creatine monohydrate is a naturally occurring compound with a well-characterized mechanism: it increases intramuscular phosphocreatine stores, enhancing ATP regeneration during high-intensity exercise. The mechanism has been validated by magnetic resonance spectroscopy, muscle biopsy data, and over 500 randomized controlled trials. It is the most studied and most effective ergogenic nutritional supplement available, as confirmed by the ISSN, ACSM, and EFSA.

Evidence for Turkesterone in Humans

The critical question for any supplement is not whether it does something interesting in a petri dish or a rodent model, but whether it produces measurable benefits in humans at practically achievable doses. For turkesterone specifically, the answer is straightforward: there is essentially no published human evidence demonstrating that turkesterone supplementation improves muscle mass, strength, or exercise performance.

The most relevant human study is Isenmann et al. (2019), which examined the effects of ecdysterone (a related but different ecdysteroid, 20-hydroxyecdysone) supplementation during 10 weeks of resistance training in young men. The study found a significant increase in lean mass in the ecdysterone group compared to placebo. However, several important caveats apply:

• The study tested ecdysterone, not turkesterone. These are different compounds with different pharmacokinetic profiles, and results from one cannot be assumed to apply to the other.
• The study had a small sample size (46 participants across three groups).
• Independent analysis of the supplement used revealed that the actual ecdysterone content was only about 6% of what was declared on the label, raising serious questions about what the participants actually consumed.
• The study has not been independently replicated.

The Bioavailability Problem

Even setting aside the lack of human trials, turkesterone faces a fundamental bioavailability challenge. Ecdysteroids are rapidly metabolized and have poor oral bioavailability in mammals. The doses that produce effects in cell culture and animal studies may not be achievable through oral supplementation at commercially available doses (typically 500 to 1000 mg/day). The actual amount of active compound reaching muscle tissue is unknown because the pharmacokinetics have not been characterized in humans.

The Purity Problem

Third-party testing of turkesterone supplements has repeatedly found that many products contain little to no turkesterone. The Ajuga turkestanica plant material itself contains only trace amounts of turkesterone, making consistent high-dose extraction difficult and expensive. This is a systemic quality control issue in the turkesterone supplement market.

Evidence Comparison

Why Turkesterone Got Popular

Turkesterone's popularity is not an evidence story. It is a marketing story. Several factors contributed:

• Influencer promotion: High-profile fitness influencers, many with affiliate relationships with turkesterone supplement companies, promoted the compound to millions of followers.
• The "natural anabolic" framing: Positioning turkesterone as a steroid-like compound that is natural and legal appeals to a market that wants steroid-like results without steroids.
• Novelty premium: New supplements generate excitement. Creatine has been around for 30 years and does not generate clicks.
• Price anchoring: High price ($40 to $70/month) reinforces the perception that turkesterone is a premium, effective product. Cheap creatine does not carry the same perceived value.

None of these factors have anything to do with evidence.

When Each Makes Sense

Creatine: For Anyone Who Trains

Creatine is appropriate for any individual engaged in resistance training, high-intensity interval training, team sports, or any activity involving repeated bouts of high-intensity effort. It is the single most effective ergogenic supplement available, it costs less than a daily coffee, and its safety has been confirmed across decades of research.

Turkesterone: Not Recommended

Based on currently available evidence, there is no justification for recommending turkesterone supplementation. There are no human studies demonstrating efficacy for the specific compound, the pharmacokinetics are unknown, product purity is unreliable, and the cost is 3 to 5 times that of creatine. If future well-designed human trials demonstrate benefits, this assessment will change. The evidence drives the conclusion, not the marketing.

Verdict

This comparison is perhaps the most asymmetric in supplement science. On one side: three decades of research, hundreds of studies, consensus from every major sports nutrition body, a well-understood mechanism, excellent safety, and a cost of roughly $0.30 per day. On the other: social media popularity, no human trials for the specific compound, unknown bioavailability, documented labeling fraud, no expert endorsement, and a cost of $1.50 to $2.50 per day.

The turkesterone phenomenon is a useful case study in critical thinking about supplement claims. When a supplement is primarily promoted through social media rather than peer-reviewed journals, when the people promoting it profit from its sale, when the price is high and rising, and when the evidence consists of "it's a steroid hormone in insects so it must build muscle in humans," the appropriate response is skepticism. Creatine earned its reputation in the laboratory, not on social media. That distinction matters.
