Optimized Trader Bundle

In one study of 17 male London derivatives traders, morning testosterone predicted profitability for the rest of the trading day. Most traders have never measured theirs.

Kim Ann Curtin has spent over 20 years coaching institutional traders, hedge funds, and senior executives, including clients affiliated with GIC, Morgan Stanley, Bank of America, King Street Capital, BC Partners, and Blackstone. Somewhere along the way, she noticed a pattern psychology alone couldn’t always explain: clients doing the mindset work, following their rules, and journaling their trades who still weren’t moving the needle. The missing piece wasn’t necessarily more discipline. Biology could be part of the picture.

Research out of Cambridge points to this connection. In a field study of 17 male London derivatives traders, higher morning testosterone significantly predicted greater profitability during the remainder of that trading day, while cortisol tracked the variance of traders’ returns and market volatility rather than losses alone. Researchers have proposed that winning streaks may raise testosterone, increasing confidence and appetite for risk, sometimes past the point where it is still working in a trader’s favor. Read the full research breakdown here.

The Optimized Trader Bundle is Kim’s answer to that gap: real lab data on your own biology, interpreted by a specialist, paired with a coaching session that connects what your numbers say to how you actually trade.

Investment

This is not medical advice or disease treatment. It’s about using your own health data to support your trading performance. If you suspect you’re ill, seek medical advice from a licensed provider. Kim does not prescribe or diagnose; any treatment planning happens directly with Marek Health’s licensed partnered clinicians.

How It Works

Testimonials describe individual client experiences. Coaching does not guarantee trading performance or financial results. Trading involves risk, including the possible loss of principal.

Frequently Asked Questions

Is this a testosterone replacement therapy clinic?

No. Marek Health is a diagnostic and optimization service, not a prescription-first telehealth clinic. The point is data and interpretation first. Some traders’ results may identify treatment options worth discussing with a licensed clinician; many may not need treatment at all. The process begins with data and interpretation, and treatment is considered only when clinically appropriate.

Do I need to already be coaching with Kim to buy this?

No. The one-hour coaching session is included in the bundle and isn’t sold as a standalone otherwise, so this works as a starting point even if you’ve never worked with Kim before.

How long does the whole process take?

Plan on 3 to 4 weeks from ordering to your coaching session: a few days to get your requisition, a blood draw, 7 to 14 days for lab results, then your two calls.

What if I’ve already had bloodwork done recently?

Bring it up on your health coach call. Routine bloodwork often does not include a comprehensive thyroid or sex-hormone panel. When thyroid screening is performed, TSH is generally the primary screening test, with additional thyroid tests ordered when appropriate. The Marek panel may therefore provide meaningfully more information even when you have had recent bloodwork.

Is the lab panel available in every state?

Yes, in all 50 states. For residents of New York, New Jersey, and Rhode Island, the lab requisition is handled through Quest, and Quest bills you directly after testing rather than the cost being included upfront. In the other 47 states, everything is covered upfront with no additional billing.
