About Seb
I'm Seb, the author and editor of Male Optimal. This page is here so you understand who's writing this and what actually qualifies me to do it.
Who I Am
I'm mid-40s, UK-based, and I spent most of my career in operations management. That background shapes everything I do here.
Operations, at its core, is about understanding complex systems, sourcing reliable data, making decisions with incomplete information, and then measuring whether those decisions worked. You set KPIs, you monitor them, you adjust based on evidence. You learn to spot the difference between correlation and causation. You develop a healthy scepticism towards claims that can't be backed with numbers.
I've applied that framework to my own health for the past five years with remarkable consistency.
My Health Journey
Around age 40, I decided to get serious about my body and my health in a systematic way. I'd trained irregularly for years — some periods intense, some negligent. My diet was reasonable but not optimised. I had no baseline understanding of my own biology.
So I did what I'd do with a business problem: I got data.
I had bloodwork done. Testosterone, oestrogen, thyroid, lipids, cortisol, inflammatory markers — the full panel. I wanted to know where I actually was before trying to go anywhere.
Testosterone came back "normal" by NHS standards. It was roughly 16 nmol/L, right in the middle of their reference range. But "normal" and "optimal for my goals" aren't the same thing. I wanted the body composition and energy associated with the higher end of that range.
I started researching rigorously. I read papers on PubMed. I looked at what the evidence actually said about testosterone, training, nutrition, and body recomposition. I found out how the UK hormone system works — the NHS model, the private practitioners, what compounds are accessible here and what the legal landscape actually is.
And yes, I experimented. Cautiously. With medical oversight where appropriate. I've taken testosterone. I've taken other compounds I write about. I've tracked my bloodwork before, during, and after. I've lived with the results — the good ones and the side effects.
That experience informs everything here. When I write about testosterone replacement, I'm not writing theory. I'm writing about something I've done, measured, and refined.
What I Actually Know
I'm not a doctor. I don't have the medical training a doctor has. I didn't go through medical school. I can't diagnose conditions or prescribe treatments.
I'm not a registered dietitian. I haven't done a formal nutrition qualification. But I have read hundreds of nutrition papers, understood the evidence hierarchy, and built enough knowledge to discuss nutrition meaningfully.
I'm not a certified personal trainer. I haven't taken formal coaching qualifications. But I've trained seriously for 12+ years, read extensively about training science, and know how to program for hypertrophy and performance.
What I am is a rigorous researcher. I can find primary sources and read them critically. I understand study design and evidence grading. I know the difference between "promising preliminary findings" and "established fact." I'm comfortable saying "we don't know yet" or "the research is mixed."
I've built systems for my own health — training protocols, supplement stacks, dietary approaches — and measured whether they work. I've made mistakes and learned from them. I've changed my mind when evidence warranted it.
My Approach
Everything on Male Optimal reflects this analytical framework:
Primary sources first. If I cite something, you can trace it back to a study, a regulatory body, or an expert source. Not to someone else's blog post about a study.
Evidence grading. Randomised controlled trials in healthy humans tell us something different than a mechanistic study in mice. Both are useful. Both are limited. I try to be clear about which is which.
Honest about uncertainty. If research is preliminary, I say so. If there's genuine disagreement among experts, I present it. If something is my opinion based on experience rather than hard evidence, I'm explicit about that.
No hidden incentives. Yes, Male Optimal uses affiliate links. Yes, I benefit financially if you buy through them. That relationship is disclosed. But it never determines what I write or what I recommend. If anything, the disclosure requirement makes me more cautious — these recommendations have my name on them.
Safety-first framing. We cover some serious content. Anabolic steroids, prescription hormones, compounds that carry real risks. We don't hide from that because hiding doesn't serve anyone. But we always flag risks, always recommend medical oversight, and we're explicit that we're educating, not prescribing.
What I Cover
On Male Optimal, I write about:
- Testosterone: physiology, optimisation, replacement, side effects, legal and ethical considerations
- Oestrogen: why it matters, how it affects men and women, aromatase inhibitors, balance
- Other hormones: thyroid, cortisol, growth hormone, IGF-1, prolactin, and how they interact
- Supplements: which ones have evidence, which ones don't, how they compare to pharmaceutical interventions
- Training: how to programme for hypertrophy, performance, and aesthetics
- Nutrition: protein requirements, micronutrient sufficiency, dietary approaches that actually work
- Bloodwork: how to interpret tests, what markers matter, what the NHS offers vs. what private testing provides
I write for the UK audience specifically. American protocols, legal statuses, and practitioner recommendations often don't apply here.
Corrections and Updates
If I've made a factual error, I'll correct it. If new research emerges that changes my understanding, I'll update the guides. If you've spotted something wrong, you can contact me and I'll investigate.
Health information is not static. My job is to keep pace with the evidence and communicate accurately.
