I spent two decades cycling. I know what supraphysiological testosterone feels like. I know what the come-down feels like. I know what the post-cycle months feel like when you’re dragging yourself out of bed and wondering whether the version of you in the mirror is the floor or just a step on the way down. I have done the full carousel.
What I’m doing now, at 43, isn’t a cycle. It’s not a blast. It’s not a “natural” charade either. I’m on testosterone replacement therapy — microdosed, daily, life-long — and it’s the single best decision I’ve made for my training, my mental health, my libido, and my long-term healthspan since I started chasing this stuff as a teenager. This article is what I’d tell my 38-year-old self if I could go back.
What “Microdosed” Actually Means
The standard TRT protocol most clinics push is 200 mg of testosterone cypionate or enanthate once a week, intramuscular. That’s it. That’s the script.
The pharmacokinetics on that protocol are a disaster. Cypionate has a half-life of about eight days. When you inject 200 mg on Monday, your serum testosterone spikes into the 1200 to 1500 ng/dL range by Wednesday or Thursday — well into supraphysiological territory. By Sunday night your levels have crashed back into the 600 to 800 range, which is where you want to be, but you got there from the wrong direction. Your estrogen has spiked because aromatase is working overtime to convert that excess test. Your hematocrit is rising because high test pulses drive erythropoiesis. Your mood is on a roller coaster.
Microdosed TRT splits that 200 mg into smaller, more frequent injections. My personal protocol is 28 mg of testosterone cypionate, subcutaneous, every other day. That works out to 98 mg per week — slightly less than the standard 200 mg protocol because daily-equivalent stable levels are more efficient and require less drug to achieve the same physiological state.
The result: my serum testosterone is steady in the 850 to 950 ng/dL range across the entire week. Estrogen tracks proportionally and stays where my body wants it. No spike, no crash. I don’t feel the injection. I just feel like me.
Why I Made the Switch
By 41 I was waking up at 4 am with my mind racing about everything and nothing. Sex drive was inconsistent. My morning erections — the honest barometer most men ignore — had become sporadic. I was lifting hard but recovery was longer than it had been at 35. My motivation in business was fine but the edge, the wanting, the drive to crush, was duller.
I got bloodwork. Total testosterone was 412 ng/dL. Free testosterone was below the reference range. SHBG was elevated. I had every clinical justification for replacement and I was watching my body and brain quietly decline because the medical system in most places treats anything above the absolute floor of normal as “fine.”
It’s not fine. The “normal” reference range is a population average that includes 80-year-old men on the bottom end. Telling a 41-year-old his 412 is “in range” is malpractice dressed up as evidence-based medicine.
My Exact Protocol
I’m going to give you the exact numbers because vague advice is useless. This is what I run.
Testosterone cypionate: 28 mg every other day, subcutaneous, abdomen or thigh. I rotate sites. Insulin syringe, 31 gauge, 5/16 inch. The injection is painless.
HCG: 250 IU twice weekly, subcutaneous. This maintains testicular function and intratesticular testosterone. Without HCG on a TRT protocol you will atrophy and your fertility will go. Some men don’t care. I do, and so should you if you’re under 50.
Anastrozole: 0.125 mg twice weekly, oral. Microdose. Most men on microdosed TRT don’t need an aromatase inhibitor at all because the steady levels keep estrogen in check. I’m an aggressive aromatizer — I always have been — so I run a tiny dose to keep my estradiol in the 25 to 35 pg/mL range. If your bloodwork shows your E2 is below 20, drop the AI entirely.
Daily TADALAFIL: 5 mg every morning. Not for ED — I don’t have ED. For vascular health. There’s good data on low-dose tadalafil improving endothelial function long-term. Cheap insurance.
The Bloodwork I Actually Run
You cannot run TRT without bloodwork. If you’re cooking your protocol off how you “feel,” you’re going to wreck yourself.
I get a full panel every twelve weeks. Total testosterone, free testosterone, SHBG, estradiol (sensitive assay — the standard ECLIA is useless for men), CBC with hematocrit, comprehensive metabolic panel, lipid panel, PSA, IGF-1, thyroid panel including reverse T3, ferritin, vitamin D, B12, folate.
Hematocrit is the number that matters most for safety. TRT drives red blood cell production. If you push your hematocrit over 54%, your blood becomes too thick and your cardiovascular risk climbs. My hematocrit on this protocol sits at 48 to 50%. If it climbs over 52, I donate blood at the Red Cross. Cheap, easy, problem solved.
PSA gets checked because I have a family history. Mine is steady at 0.8. TRT does not cause prostate cancer despite the persistent myth — it does not. But if you have an undetected prostate cancer, exogenous testosterone may accelerate its growth. Screen and screen often.
What Changed Within Three Months
Sleep first. The 4 am wake-ups stopped completely inside of three weeks. Whatever the mechanism — and there’s literature on testosterone’s effects on slow-wave sleep — I sleep like a 25-year-old. Eight hours, deep, uninterrupted.
Libido was back inside of two weeks. Morning erections every morning. The kind of consistent, unprompted, default-state arousal that any man knows means his hormones are working.
Body composition shifted slowly but predictably. I dropped 6 pounds of fat across the first 12 weeks and gained about 4 pounds of lean mass without changing my training or diet meaningfully. The slow shift is the point — this isn’t a cycle, this is your body returning to its set point.
Cognitive sharpness — and this is the one most men underrate — came back hard. The flat affect, the procrastination, the lack of give-a-damn for projects I’d been excited about a year before. All gone within four weeks.
The Mistakes Most Clinics Make
Going too high too fast. The clinic that prescribes 200 mg/week on day one is dosing you like a bodybuilder, not a patient. Start at 100 to 120 mg/week total, split into daily or every-other-day microdoses, and adjust at 8-week intervals based on bloodwork and how you feel.
Skipping HCG. A doctor who tells you HCG “isn’t necessary” and lets you atrophy is either ignorant or lazy. HCG protects testicular function and supports fertility, mood, and the psychological piece of feeling like a man instead of a man on a script.
Slamming the AI. I have seen clinics put men on 1 mg of anastrozole twice weekly off the bat. That’ll crash your estrogen to single digits, destroy your libido, ruin your bone density, and make you feel like garbage. Estrogen is essential for men. The goal is to manage it, not crush it.
Not measuring estradiol with a sensitive assay. The standard E2 test cross-reacts with other steroids and overstates your number, leading to overaggressive AI dosing. Insist on the sensitive (LC-MS) assay.
The Cost of Doing It Right
A telehealth TRT clinic in the US will charge you $150 to $250 per month for testosterone, HCG, anastrozole, and clinical oversight. That’s $1,800 to $3,000 per year. Quarterly bloodwork through a service like Marek or directly through Quest is another $200 to $400 per year.
For roughly $3,000 a year — less than most men spend on streaming subscriptions, gym memberships they don’t use, and online gambling — you get the testosterone profile of a healthy 28-year-old, indefinitely. The math is laughable.
Pairing TRT With the Rest of My Stack
TRT is the foundation. Everything else stacks on top.
I run BPC-157 and TB-500 twice a year as a maintenance protocol for joint and tendon health. I run CJC-1295 and Ipamorelin at night for growth hormone optimization. I take rapamycin once weekly for autophagy and longevity. I cycle metformin off-and-on for insulin sensitivity. I run a full anti-aging supplement stack daily.
None of this works as well without optimized testosterone underneath. That’s the lesson. The foundation has to be right or the additions are noise.
The Honest Downside
Once you’re on, you’re on. The HPTA shuts down with exogenous testosterone over months. Restarting natural production takes 6 to 18 months of careful PCT with clomid or enclomiphene, and many men never fully return to baseline. I made peace with this. If you’re 30, healthy, and want kids — think hard before you start. If you’re 45 and your body is already running on fumes, the trade is obvious.
Long-term cardiovascular safety data on TRT is good but not unlimited. The TRAVERSE trial put a lot of fears to rest, but we don’t have 40-year prospective data because the modern microdosed protocols haven’t existed that long. I am betting on the mechanism, the consistent bloodwork, and the symptomatic improvement. So far, every marker I track is better than it was at 41.
Final Word
If you’re over 40 and your testosterone is below 500 and you’re feeling the things I described — the sleep, the libido, the motivation, the recovery — get on TRT. Find a clinic that runs microdosed protocols, daily or every-other-day injections, real bloodwork with sensitive assays, HCG support, and conservative AI dosing.
The version of yourself you’ve been settling for is not the version you’re stuck with. The medical system in most countries is conservative to a fault. You are the only person who’s going to advocate for your hormones. Do it.

Frequently Asked Questions
What is microdosed TRT and how does it differ from steroid cycling?
Microdosed TRT uses low, consistent testosterone replacement within physiological ranges (typically 50-100mg weekly) rather than supraphysiological blasts. Unlike cycling, which involves high doses followed by crashes, microdosed TRT maintains stable hormone levels, avoiding the post-cycle depression, mood swings, and performance drops experienced by traditional users.
Is microdosed TRT safer than traditional testosterone cycling?
Microdosed TRT carries fewer extreme risks than high-dose cycling. It minimizes cardiovascular stress, hormonal crashes, and androgenic side effects from peak levels. However, it's not without risks—long-term suppression of natural production, potential prostate effects, and dependency remain considerations. Medical supervision is essential.
Can you build muscle on microdosed TRT after cycling for years?
Yes. Microdosed TRT maintains testosterone at levels sufficient for muscle preservation and modest gains, especially in experienced lifters with training history. While gains are slower than supraphysiological doses, the stable hormone environment supports consistent progress without the metabolic crashes that follow traditional cycles.
