For the past 10 years I’ve enjoyed running, however since turning 50 I’ve had more smaller injuries and libido is almost non existent.
I run about 40 miles per week, and up to 70 miles if training for a planned endurance event, Ultramarathon events up to 56 miles and I run one ultramarathon event each year and then have 12 weeks off from running. Most of my running is done wearing a heart rate monitor, training in different hr zones. I have excellent aerobic capacity and vo2 max for my age.
At the moment I am waiting on blood results for low testosterone. I have read that endurance running can suppress testosterone. With trt, then my testosterone would be stable and I would have better recovery from runs and libido would return ?
Not necessarily,
Im a similar athlete/age to you (55), have been on TRT for nearly 5 yrs now…
Cant say as its made any difference to my sports performance and libido is up and down dependant on a myriad of other factors we all experience.
Your regimen is likely killing your Testosterone. You can’t feed both animals and frankly, endurance training puts a strain on your Testosterone production.
You may have to choose between continuing to train or having normal T levels.
TRT may be beneficial. Wait for your bloods and then decide.
If it hasn’t made any difference, why are you continuing with it ? If you discontinued trt then would you be better or worse ?
Did mood, motivation, libido improve when you started, and did your body composition improve. I think diet wise there is a lot that can be done to improve the above said. I rarely drink alcohol and eat a good diet.
You’re right, I know that my training is having a negative impact on my testosterone levels, but age is also a factor.
Still waiting on test results, my suspicion is that the result will be low. With trt, I am not looking to be in the higher range of normal as I don’t really want additional weight gain. Just enough to feel physically and mentally sexually well .
I assume you meant 5’10" and 147 pounds. I know us Murricans are a little wack on the measurements, but that is the only thing that makes sense to me with respect to 5.10 and 10.5 stone.
I guess the big question is what are your goals?
Do you want to keep running Ultras?
Clearly you are in a caloric deficit and should weigh closer to 12.5 stones and this is why your T levels might me low.
I’m 6’1", 190. I can’t run a mile, lol, but look pretty good at sixty.
The higher normal range (Free T) decreases prostate cancer risk and reoccurrence by 53%, risk of dying, heart attacks, strokes and all cause mortality is significantly lower.
Your comment about weight gain with high testosterone is false, it’s the other way around. Too many men believe they are going to look like Dwayne Johnson on TRT, that’s just not reality.
The NHS is a joke to start with, their position is often of ignorance! Medicine doesn’t advance as quickly as it does in a free market without government control.
Can you imagine if the VA controlled all of healthcare in the US?
There is evidence that consistent levels of testosterone above 30 nmols can increase your risk of developing cardiovascular disease i.e heart disease and strokes.
Water weight gain is my main concern, if I was after a rock type physique then would be looking to blast upwards of 200mg - 2000mg per week of testosterone with some HGH, insulin and T3 thyroid, Clenbuterol…
Check your iron/ferritin levels too.
Ive noticed mine are quite low on the last couple blood tests, probably a combination of the endurance exercise and TRT, both of which are known to deplete it.
Many are confused AAS, where testosterone cypionate is used with other compounds (DHT derivatives) used in conjunction with bioidentical hormones that cause organ damage.
To my knowledge, to date there are NO long term controlled studies showing the effects of long term high dosage testosterone cypionate 30> nmol/L in isolation without any of the aforementioned compounds.
I won’t deny that very high testosterone in isolation may cause left ventral hypertrophy.
My initial blood test is for total and free testosterone and sbhg and albumin. But will have a 2nd more detailed test that will check for over 40 bio markers, so will look at that
Testosterone as little as TRT levels over time can increase hematocrit and that can cause stroke, but that’s easy to monitor at home with Fora multi parameter testing device. I know of bodybuilders who used up to 5 grams of test per week and are now approaching 60 years of age and seem healthy.
that weight would be too much to carry and don’t think would be good for my joints. Thanks
