42, thinking about starting TRT — looking for advice

I'm 42, 6'1", been lifting since about 17. I always liked the gym but between kids, running businesses and life I got inconsistent and packed on weight. Three months ago I committed again. I started at 258 lbs and my total testosterone was 530. Since then I'm training about five days a week, cleaned up my diet, making sure I hit protein, and taking Reta 3.5mg/week to help with weight loss. I'm down 18 lbs to 240 now. A DEXA put me at 28% body fat. I had a full blood panel last week and my total test rose to 602. A provider has prescribed 200 mg/week of testosterone, but I haven't begun it. My main worry is I still carry a fair amount of fat and I'm concerned about increased aromatization and estrogen-related side effects (my estrogen is in range). I've never used testosterone or other PEDs before, so this would be new. I'm not trying to be a bodybuilder — I want to lose another 25–35 lbs, keep as much muscle as possible, add some size, and feel strong and athletic again. One thing I've noticed since returning to training is recovery isn't what it used to and I don't have the same energy/drive I did when I was younger, which I get is normal. I realize my natural testosterone levels a…

How comprehensive was your last panel? 602 total is great for your age, but it's not the whole story. If everything else checks out, a light TRT regimen could help with fat loss, but 200 mg/week is likely too high if you're already around 600. What was your free T? Definitely keep dropping fat before considering cycles. Test-only could restore some drive. Also get your diet locked in — 18 lbs in 3 months is good, but with your setup I think you could push harder.

I had a full panel and everything else looks fine. My free testosterone is 87. What would you define as a low TRT dose? I understand even a small dose can suppress natural production, so what's a reasonable starting point? I'll be checking labs every ~40 days to watch for any markers drifting out of range. Also, should I have an AI on hand, or wait to see if estrogen rises? I deliberately paced my weight loss to be sustainable, which is why it wasn't faster.

So your free T is a bit low, but not catastrophic. One major question: are you prepared to stay on TRT indefinitely? It will suppress your natural production, so you need to accept long-term use or not start. No rush since you're making progress. I usually recommend 100 mg/week to begin, then labs at 6 weeks. I try to keep total T around 750–800 on TRT, which for me puts free T just under 200. Watch estrogen (E2) and hematocrit closely. If you're a strong responder and your total goes over 1000, you can reduce dose. Daily microdosing can smooth levels and allow smaller overall doses, but for a first-timer stick with twice-weekly injections.

You don't need an AI sitting ready — if you end up needing one, you're effectively running a cycle, not classic TRT. I began at 120 mg/week split twice. After 6–8 weeks I did labs, then went to 160 and rechecked — I was mid-600s so adjusted. Everyone reacts differently. I'm only ~6 months in, but the common advice here is go slow. TRT was one of the best choices I made, but I was in the low 300s and had no libido, which was my main issue.

That's the route I was leaning toward — start low, go slow, monitor bloods and see how I feel. My biggest fear is knocking out my natural production when I'm already around 600 and ending up back where I started. Glad to hear it's worked well for some people though — encouraging.

I'm open to staying on TRT long-term if it gives me better recovery, more muscle, strength and energy. My worry is whether raising total T from ~602 to the 750–800 range would actually feel meaningfully different. Would the gains justify suppressing my natural production? Down the line, once I'm leaner and understand my response and labs, I might run a blast to add size, but I'm not trying to rush. If you were in my position — decent natural T but wanting better recovery and muscle — how would you proceed? Appreciate the input.

In theory your natural levels should improve or at least stay better as you lose more bodyfat. If you could boost free T naturally you might notice changes. What were your SHBG and E2 values?

If I can share my experience: TRT changed things for me at 57. I'm on Test Cyp, 200 mg split into two injections a week — Monday morning and Thursday evening — about.60 ml each shot. My trough on Thursday morning before the shot was around 850 ng/dL and by Saturday I was ~1100 ng/dL. A bit high for some, but it's working for me. I get bloods every 8 weeks to watch LDL and hemoglobin. I donate a pint of blood every 3 months to keep RBC in check and monitor iron. I'd suggest starting low (.25 ml twice weekly) and run it for about 60 days to see how you respond. Go slow and steady to dial in what works. TRT also helped my metabolism and weight loss. Not a doctor, just my experience.

At 530 I'd stay natural. Keep monitoring bloodwork and switch only when you actually need to. 530 is a solid number for a guy your age.

My SHBG is 39 and E2 is 20. I'm hoping dropping another ~20 lbs will nudge my T higher. I'm a bit uncertain which path to take — keep my hormones natural or start TRT to help build muscle. I know I can make progress naturally, but I'm also considering future compounds. Just trying to balance health and my physique goals.

Thanks for the thoughts. I'm fine staying natural for a while, but like others here I want a physique that stands out. I feel like that will be tougher without some assistance down the line.

Honestly, with those numbers I'd stick with natural for a while longer. Lose more bodyfat then re-evaluate. You're in a better hormonal position than many guys in their 40s, which is impressive given you were overweight. I get the feeling of running out of time — I'm 47 — but it's still best to do this right. Keep pushing the fat loss goals.

Quick take: understand TRT and AAS carry weighty commitments, especially long-term commitment. It's a lifestyle with consequences. Unless your plan is to cycle and chase significant mass gains, you're probably better off staying natural given where your numbers are. Keep losing a bit more fat, repeat bloodwork later and reassess. Right now jumping on TRT might be premature. Just my two cents.
