Three Clients, Same Bloodwork, Completely Different Root Causes – What I Learned

• Total testosterone is a headline number. It tells you that a problem exists. It does not tell you why the problem exists. Three clients I have worked with over the years came in with testosterone in the 380-430 ng/dL range, within a handful of points of each other, and every single one had a completely different root cause driving the suppression.
• Aaron’s total T was 720 and he felt terrible. Earl’s total T was 360 and his doctor said he was fine. Patrick’s total T was 410 and no standard intervention was going to touch the real problem. The lesson in all three cases is the same: the number is the symptom. The cause requires a different investigation.
• If you are running a protocol based on your total testosterone reading alone, you are optimizing the wrong variable.

The most expensive habit a man can have is treating a testosterone number as a diagnosis rather than a symptom. I see this constantly – a man gets bloodwork, sees 380, decides the answer is a testosterone-raising supplement stack, runs it for 90 days, sees his number go to 420, decides the protocol is working, and continues for another six months while the thing that is actually wrong with him gets worse beneath the surface. I have written about this from the protocol side at PowerandBulk.com across the cornerstone articles. This piece is the case-study version – three men, three root causes, one diagnostic lesson.

Aaron Pell taught me that high total testosterone means nothing if SHBG is stealing it. Earl Lindberg taught me that testosterone is downstream of thyroid, and a man who does everything right will never recover his testosterone until his thyroid is treated. Patrick Sullivan taught me that the HPA axis can suppress testosterone in a way that no lifestyle optimization touches until the nervous system suppression is addressed first. Three entirely different mechanisms. Three entirely different protocols. Three men who would all have failed conventional T-optimization approaches because those approaches start from the number rather than from the cause.

Aaron Pell: The Man With “Good” Testosterone Who Felt Terrible

Aaron came to me at 31. Financial planner in Denver. Married, planning for his first kid. Lean, active, ate well, trained three days per week. He came in because he felt off – low energy, reduced motivation, libido not where it had been, recovery from training slower than expected. His total testosterone when he pulled bloodwork on his own before our first call: 720 ng/dL.

By every standard interpretation, that number was excellent. His GP had told him exactly that. “Your testosterone is great.” Aaron was not satisfied because he felt like someone whose testosterone was not great, regardless of what the number said.

I asked him to run a fuller panel. Free testosterone calculated at 8.4 pg/mL – low. SHBG at 78 nmol/L – very high. Thyroid panel: TSH 3.4, free T3 low-normal. Magnesium intake from his food log: near zero.

This is the case I reference more than almost any other when explaining why the complete hormone panel matters. Aaron’s total T was 720 because his testes were producing testosterone at a reasonable rate. His free T was 8.4 because his SHBG at 78 was binding almost every molecule of testosterone before it could do anything. He had the production but not the delivery. The car was full of gas. The fuel injectors were clogged.

The root cause investigation: his thyroid was mildly suppressed, which elevates SHBG through a mechanism involving hepatic sex hormone binding globulin production. His magnesium was essentially zero, which matters because magnesium competes with testosterone for SHBG binding sites – adequate magnesium keeps more testosterone unbound. And his total SHBG was genetically on the high end, meaning the thyroid suppression and magnesium deficiency were pushing an already-elevated baseline into a range where free T became functionally deficient.

The protocol had nothing to do with raising testosterone. Aaron’s T did not need raising. We worked on thyroid support – selenium 200mcg, iodine from kelp, zinc 25mg, optimizing his T4-to-T3 conversion. Magnesium glycinate 400mg at bedtime. Boron 9mg with breakfast to compete with testosterone at SHBG binding sites. No Tongkat ali, no Fadogia, no testosterone-focused supplement at all.

Marker	Baseline	Month 4	Change
Total testosterone (ng/dL)	720	694	-26
Free testosterone (pg/mL)	8.4	21.2	+12.8
SHBG (nmol/L)	78	48	-30
TSH	3.4	2.1	improvement
Free T3	low-normal	mid-range	improvement

Total testosterone actually dropped slightly – 694 versus 720. That does not matter at all. Free testosterone climbed from 8.4 to 21.2 pg/mL, more than doubling. That is what Aaron felt. He texted me at month 3 to say: “I had no idea this was what feeling normal was supposed to feel like.” His wife was pregnant by month 8. Not directly attributable to the protocol, but he mentioned it and I noted it.

The lesson: in a man with high-normal SHBG, total testosterone tells you almost nothing about his functional androgen status. The panel that mattered for Aaron was free testosterone, SHBG, and thyroid – not total T. The protocol that mattered addressed none of the conventional T-raising targets.

Earl Lindberg: The Man Who Did Everything Right and Felt Wrong

Earl Lindberg came to me at 53, dairy farmer in rural Wisconsin. Married, three adult kids who ran the farm with him. Physically active all day – real work, not structured exercise, but genuine sustained physical labor. He ate his own farm food, which meant grass-fed beef, eggs from his own chickens, raw dairy. He did not drink. He did not smoke. He was in bed by 9pm and up at 4:30am. By every lifestyle heuristic, this man should have had excellent testosterone.

He did not. Total T at 360 ng/dL. He had been to his GP and been told his thyroid panel “looked fine” – TSH was 4.1, which is inside the 0.5 to 5.5 reference range most labs use. His doctor’s interpretation: normal. His body’s interpretation: not.

I suspected thyroid from the first call. The pattern – doing everything right, eating correctly, sleeping well, physically active, no suppressors, and still functionally low T – is the thyroid pattern almost every time in my experience. When everything that should raise testosterone is present and it is not raising, look at the thyroid. Look at the full panel, not just TSH.

Earl’s full thyroid panel: TSH 4.1 (inside reference range but above optimal 1.0-2.5 range). Free T3 low-normal. Reverse T3 elevated (reverse T3 is an inactive form of thyroid hormone that competes with active T3 at cellular receptors – elevated levels mean the body is producing thyroid hormone but blocking its own use of it). TPO antibodies elevated at 84 IU/mL (normal below 35) and TG antibodies slightly elevated. The diagnosis was Hashimoto’s thyroiditis – an autoimmune condition causing low-grade thyroid inflammation and suppression that can persist for years undetected when only TSH is tested.

Earl had been subclinically hypothyroid for an unknown period. His GP had been checking only TSH and declaring him normal. His body had been running with inadequate thyroid hormone for years, which suppresses testosterone through multiple pathways – reduced LH receptor sensitivity at the testes, elevated SHBG from impaired liver function, and general metabolic suppression that reduces steroidogenic enzyme activity.

I referred Earl to a functional medicine physician for thyroid management. This is outside my scope – I do not prescribe medications. The physician added low-dose desiccated thyroid (a natural thyroid medication derived from porcine thyroid that contains both T4 and T3, as opposed to synthetic levothyroxine which contains only T4) and worked with Earl to lower his TPO antibody load through dietary intervention – eliminating gluten for 90 days, which has a meaningful evidence base for Hashimoto’s autoimmune activity reduction.

Marker	Baseline	Month 6	Change
Total testosterone (ng/dL)	360	580	+220
TSH	4.1	1.8	normalized
Free T3	low-normal	mid-range	improved
Reverse T3	elevated	normal	resolved
TPO antibodies (IU/mL)	84	41	-51 (reduced)
SHBG (nmol/L)	46	38	-8

220 ng/dL of testosterone in six months without a single testosterone-specific intervention. Earl had not changed his diet, his sleep, his training, or his lifestyle at all – because there was nothing wrong with those. The only thing that changed was his thyroid being treated. His testosterone recovery was the downstream consequence of finally giving his entire endocrine system the thyroid signal it had been missing.

Earl’s case is the one I use when a man tells me he has “tried everything” and his T is still low. I ask him what his full thyroid panel shows – not just TSH, but free T3, reverse T3, and antibodies. The answer has surprised me enough times now that I never skip it.

Patrick Sullivan: The HPA Axis Problem

Patrick Sullivan came to me at 34, paramedic in Boston. Married, one kid. He worked 24-hour on, 48-hour off rotations. His job involved sustained high-intensity stress exposure followed by poor sleep followed by sustained high-intensity stress exposure. He had been running this schedule for nine years.

His total testosterone at intake was 410 ng/dL. His HRV, when he eventually got a wearable, was 28 ms – very low for a 34-year-old. His morning cortisol was 26 mcg/dL – elevated. His cortisol pattern across the day was dysregulated: high in the morning, elevated through the afternoon (it should fall by mid-afternoon), and still elevated into evening (it should be very low). Permanently sympathetic-dominant, 24 hours a day.

The mechanism behind Patrick’s suppressed testosterone was the HPA axis (the hypothalamic-pituitary-adrenal axis – the communication chain that controls cortisol production – which competes with the HPT axis controlling testosterone when chronically activated). Chronic HPA axis activation, through sustained cortisol output, downregulates LH pulsatility at the hypothalamus. Less LH means less signal to the Leydig cells. Less Leydig signal means less testosterone. The body, reading a state of permanent emergency, suppresses reproduction. This is pregnenolone steal at the functional level – the adrenal gland is consuming the steroidogenic substrate that would otherwise become testosterone and redirecting it toward cortisol.

Any conventional testosterone protocol would have failed Patrick at this point. You cannot raise testosterone in a man whose HPA axis is commanding the Leydig cells to produce cortisol precursors instead of testosterone. The upstream driver has to be addressed before the downstream target will respond.

I treated Patrick’s case as a nervous system recovery case before a hormonal one. The protocol for the first four months: daily breathwork for five minutes morning and evening (nasal breathing at a 5-second inhale, 5-second exhale cadence – simple, effective parasympathetic activation). Cold exposure introduced slowly – 60-second cold shower finishes progressing over six weeks to brief cold plunge sessions. Magnesium glycinate 400mg at bedtime. Phosphatidylserine 300mg post-training to blunt the post-exercise cortisol spike. No training heavier than moderate until HRV had recovered to at least 45 ms.

I also worked with Patrick on his understanding that his job was the root cause of the problem in a way that no supplement would fix. He could not change his schedule. He could change how he managed recovery within it. We built an explicit off-shift recovery protocol – the 48-hour window between shifts became a structured parasympathetic recovery period, not just downtime.

Marker	Baseline	Month 3	Month 6	Total Change
Total testosterone (ng/dL)	410	452	580	+170
Cortisol AM (mcg/dL)	26	20	16	-10
HRV 7-day avg (ms)	28	38	48	+20
SHBG (nmol/L)	28	32	36	+8
Estradiol (pg/mL)	32	27	23	-9
DHEA-S (ug/dL)	182	218	264	+82

The testosterone move in Patrick’s case lagged the cortisol and HRV improvement by about six weeks at each checkpoint. This is the pattern I expect in HPA axis-driven suppression – the nervous system recovers first, then the HPT axis recalibrates, then testosterone climbs. Trying to shortcut by adding testosterone-raising supplements before the HRV had climbed would have produced nothing. The upstream driver was still engaged. I started strength training at month three when HRV was reliably above 40, and the DHEA-S improvement tracked the training addition closely.

Patrick’s full story is more complex than one article can hold. The trauma exposure of nine years as a paramedic is a load that does not resolve from breathwork and magnesium. He is working with a therapist alongside the protocol, which I consider non-optional for first responders with the kind of sustained exposure his job involves. I treat him with appropriate respect and do not use his case as a simple “fix your cortisol” narrative. The hormonal picture improved. The underlying situation that created it is more complicated.

The Diagnostic Framework I Use With Every New Client

Three clients, three near-identical total testosterone readings, three completely different root causes. Here is the panel I pull on every new client before I write a single protocol note:

• Total and free testosterone – the headline and the actual signal
• SHBG – how much of the total is being bound
• Estradiol – aromatase load
• LH and FSH – whether the problem is primary (testes) or secondary (brain signal)
• Full thyroid panel – TSH, free T3, free T4, reverse T3, TPO and TG antibodies
• Cortisol AM – is the HPA axis in the picture
• DHEA-S – adrenal reserve
• Fasting insulin and HbA1c – metabolic status affecting SHBG and aromatase
• Vitamin D, ferritin, zinc, magnesium – deficiencies that suppress the whole system

This is the hormone panel decoder approach. Not every client needs every one of those markers at every draw – but at baseline, before I know what I am looking at, I want all of them. The total testosterone is the last thing I optimize around. The root cause is the first thing I try to find.

The reason most testosterone optimization protocols underperform is not that the interventions are wrong. It is that they are applied to the wrong root cause. Boron and zinc will help Aaron and do nothing for Earl. Thyroid treatment will transform Earl and do nothing for Patrick. Nervous system recovery will help Patrick and is irrelevant to Aaron. The intervention has to match the mechanism. The mechanism requires more than one blood test to find.

The complete hormone panel framework that drives this diagnostic approach is laid out in the full hormone panel piece. The reference range versus optimal range framing – which matters because Aaron would have been dismissed at every standard threshold – is in the reference range article. Before you run another protocol, find out which version of this problem you actually have.
