Marcus R.
From brain fog and burnout to optimized hormones, restored libido, and preserved fertility — at 37.
Total testosterone jumped from 298 to 850 ng/dL on a minimum effective dose — with fertility fully intact and a second child on the way.
The Man Behind the Labs
Marcus is a 37-year-old senior software engineer at a fintech startup — a new father to an 8-month-old, logging 50-hour work weeks, and still making it to the gym four times a week. By every outward measure, he was doing everything right.
For two years, he'd watched his energy, mental sharpness, and libido steadily erode. His primary care physician ran a single total testosterone test, returned 312 ng/dL, and told him he was "fine." He wasn't.
Before coming to FLOA, Marcus had self-directed a full supplement stack — ashwagandha, zinc, vitamin D3, tongkat ali — along with aggressive sleep optimization and complete alcohol elimination. His labs barely moved. He needed a real diagnosis and a real plan.
What He Came In With
- Persistent fatigue that sleep didn't fix — even pre-newborn
- Severe brain fog impacting performance in a high-cognitive-demand role
- Near-zero libido and intermittent erectile dysfunction
- Increasing abdominal fat accumulation despite consistent 4x/week training
- Low motivation and mild depressive mood — not depression, but a sustained flatness
- Free testosterone critically low at 6.2 pg/mL despite "in range" total T
- High SHBG (42 nmol/L) binding and inactivating available testosterone
- Early insulin resistance pattern (HOMA-IR 1.9; fasting insulin 9.5)
- Mild systemic inflammation (hs-CRP 1.8 mg/L)
- Suboptimal thyroid function (free T3 at low end of range)
- Fertility priority: second child planned within 2–3 years — testicular function must be preserved
What FLOA Designed for Marcus
Full hormone panel (total T, free T, SHBG, sensitive E2, LH, FSH, prolactin, DHT), complete thyroid panel including reverse T3 and antibodies, metabolic deep-dive (fasting insulin, HOMA-IR, full lipid panel, HbA1c, hs-CRP), and fertility planning consultation prior to protocol initiation.
120 mg/week, split twice-weekly (Monday/Thursday injections) to maintain stable serum levels and avoid the peaks and troughs of weekly dosing. Dose selected to optimize free T without overshooting E2.
500 IU HCG twice weekly maintained endogenous LH signaling, testicular volume, and sperm production throughout the protocol. Sperm banking was offered as an additional safeguard prior to initiation. Month 3 semen analysis confirmed maintained sperm parameters.
E2 monitored at month 1 and quarterly thereafter. Anastrozole reserved unless E2 climbed above the therapeutic target range. At month 5, E2 was controlled at 26 pg/mL — no AI required.
Protein-first nutrition targeting 180g/day; hypertrophy training periodization layered onto his existing 4x/week schedule; sleep optimization adapted to newborn-related fragmentation; vitamin D3 5000 IU and magnesium glycinate 400mg daily for foundational support.
Phase by Phase
Mood & Motivation Lift First
Total T reached 720 ng/dL on first recheck. E2 at 24 pg/mL — within target range. Marcus noticed a meaningful mood shift and the early return of libido before physical changes were visible.
→ First subjective wins: motivation, mood, early libido return
Sustained Energy & Cognitive Clarity
Energy sustained through full workdays for the first time in two years. Sleep quality noticeably better despite newborn disruption. Gym performance measurably improving. Brain fog clearing — a major quality-of-life shift for a high-output engineering role.
→ Cognitive performance and daily stamina restored
Body Composition Shifts — Fertility Confirmed
Visible reduction in abdominal fat. Lean mass increasing. Libido fully restored, erectile function fully restored. Semen analysis performed: sperm parameters maintained on HCG protocol — a critical milestone for Marcus's family planning goals.
→ Fertility preserved; physical transformation visible
Full Metabolic Optimization
Total T stable at 800–900 ng/dL on trough labs. Free T fully optimized. E2 controlled at 26 pg/mL — no aromatase inhibitor needed. Fasting insulin dropped to 6.8, HOMA-IR to 1.2, hs-CRP to 0.8. Vitamin D corrected to 52 ng/mL.
→ Metabolic markers normalized across the board
Stable, Sustainable, Future-Ready
Protocol confirmed at minimum effective dose. All systems stable. Second-child timing on schedule with continued HCG protocol. Quarterly monitoring cadence established for long-term management.
→ Long-term protocol locked; second child planning on track
"Two years of doing everything right with supplements, sleep, and training — and his free testosterone was 6.2 pg/mL. The problem was never discipline. High SHBG was binding his testosterone into an unusable state. No supplement stack resolves that. Targeted intervention does."
What Changed at 6 Months
Hormonal Optimization
Total T from 298 → 850 ng/dL. Free T from 6.2 → 18.5 pg/mL. E2 stable at 26 pg/mL with no aromatase inhibitor required — all on minimum effective dose.
Body Composition
Approximately 12 lbs of lean muscle gained and 15 lbs of fat lost — a net recomp of 27 lbs, with visible reduction in abdominal fat within 90 days.
Cognitive & Emotional
Brain fog fully cleared by month 2. Sustained energy through demanding 50-hour work weeks. Mood normalized — motivation and drive returned without any psychiatric intervention.
Fertility & Sexual Function
Libido and erectile function fully restored by month 3. Confirmed maintained sperm parameters on HCG protocol. Second child planning on schedule.
Metabolic Markers
HOMA-IR from 1.9 → 1.2. Fasting insulin from 9.5 → 6.8 µIU/mL. hs-CRP from 1.8 → 0.8 mg/L. Vitamin D corrected from 28 → 52 ng/mL.
Training & Recovery
Gym performance measurably improved by month 2. Training periodization layered in for hypertrophy. Sleep quality improved despite ongoing newborn disruption.
| Category | What Changed |
|---|---|
| Energy | Sustained through full workdays — no afternoon crash for the first time in 2 years |
| Mental Performance | Coding capacity, focus, and decision-making restored to pre-decline baseline |
| Libido | Near-zero → fully restored; relationship quality meaningfully improved |
| Sexual Function | Intermittent ED resolved completely by month 3 |
| Mood | Flatness and mild depressive tone lifted without psychiatric medication |
| Gym Performance | Progressive overload resumed; PRs moving again within 60 days |
| Sleep | Improved quality even amid newborn-related fragmentation |
| Parenting | More present and engaged — energy for his 8-month-old after long work days |
"I was doing everything right — lifting four times a week, sleeping as well as a new dad can, no alcohol — and still felt like I was running on empty. Getting told I was 'fine' after two years of this was the most frustrating thing I'd ever experienced. FLOA actually looked at the full picture. Six months later, I feel like myself again — except better."
Clinical Takeaways
Marcus's case is a textbook example of why total testosterone alone is an inadequate diagnostic marker. At 298 ng/dL total T, his number was technically "in range" — yet his free testosterone sat at 6.2 pg/mL, a clinically meaningful deficiency driven by high SHBG binding. No supplement protocol addresses that mechanism. The intervention had to match the actual problem.
The fertility-first approach shaped every protocol decision. By building HCG in from day one — rather than adding it as an afterthought — testicular function was preserved throughout. The month 3 semen analysis wasn't a hope; it was a planned checkpoint. That level of intentionality is what separates a thoughtful protocol from a generic one.
Finally, Marcus's outcomes weren't produced by TRT alone. The coaching team's nutrition programming, training periodization, and sleep support addressed the downstream metabolic dysfunction — early insulin resistance, mild inflammation, suboptimal micronutrients — that compounded his hormonal picture. The protocol treated the whole system, not just the number on a lab report.
