    Yes, a man in his 80s can still have good muscle mass

    It’s a very interesting phenomenon, imo, where if people see certain things become common, they think of it as “the norm”. Even if throughout our entire existence, it’s absolutely the opposite of “the norm”. So many examples I could refer to, but one that’s relevant here, is that we’re used to...

    Yes, a man in his 80s can still have good muscle mass

    It is a very interesting process, I agree. I can definitely relate. When I was younger, I don’t think I ever thought older women were unattractive, but just wasn’t my thing. But as I got a bit older, specifically around maybe 28-30, for some reason I became very attracted to older women. I just...

    FINALLY an anti-inflammatory drug protecting against heart attacks and strokes

    Wow, ur way more on top of things, diet/ health wise, than I originally assumed. So I apologize for that lol. Sounds like ur on a diet very close to what I’d probably recommend, for someone in ur position. Can u make a quick list of foods ur regularly consuming? Now I’m curious what someone with...

    FINALLY an anti-inflammatory drug protecting against heart attacks and strokes

    When u refer to being concerned about the milk proteins, are u referring to casein, or whey as well? Good job with the kefir tho. Raw kefir from grass fed cows is the least insulting way to consume dairy, as far as I know. Would be surprised if this was an issue for u, but everyone’s...

    Yes, a man in his 80s can still have good muscle mass

    Was actually just watching a comedy special where the comedian talks about this. He was basically saying how it’s wild that he’s fckn a 57 year old. Referring to his wife haha. But like u, and Einstein said, it’s all relative lol. Go to 6 mins and 30 seconds to see the part that I’m referring to

    FINALLY an anti-inflammatory drug protecting against heart attacks and strokes

    what’s ur diet look like on a daily or semi-daily basis? Guarantee there’s a bunch of foods ur still consuming that could be causing chronic inflammation/ gut issues/ auto-immune reactions. I know people seem to be harping on diet, and it’s probably annoying lol, but the reason me, and others...

    Testosterone Cypionate and Nandrolone Decanoate

    What did u end up doing after experiencing those sides? Did u figure out how to make nandrolone work for u, or did u give up on it all together?

    Injectable Progesterone SC may not be the best route of administration

    I can only speak for myself, but when I had very low free T, prior to trt, I never experienced any hot flashes. Only time I ever experienced them, and boy did I experience them, is when I took too much Arimidex, and crashed my E2. Legit hot flashes are the most insane thing ever. I empathize...

    Yes, a man in his 80s can still have good muscle mass

    Oh my bad, I didn’t realize that’s what u were referring to in ur reply. I absolutely agree tho. Carbs, as a general micronutrient, are definitely not the main issue, when it comes to diabetes. That’s not even debatable, imo. There’s plenty of fruitarians out there that don’t have diabetes. And...

    Injectable Progesterone SC may not be the best route of administration

    In which ways do u feel it? How is it compared to injectable prog, good or bad?

    Yes, a man in his 80s can still have good muscle mass

    Jc, how is resolving the root cause of the diabetes “avoiding the problem” and not curing it? From my understanding, if u remove the foods that are causing the diabetes, and u no longer have it, that’s basically “curing it” and the opposite of avoiding the problem

    Yes, a man in his 80s can still have good muscle mass

    Well obv preaching to the choir. I’m probably the biggest proponent of the importance of diet on this whole forum lol But ya I’ve heard that u basically have to take it for life. And if u stop taking it, after losing all that muscle, ur ability to use/ dispose of glucose is going to be greatly...

    Yes, a man in his 80s can still have good muscle mass

    Now that fitness and going to the gym and eating healthy are such popular things, it’s going to be really fascinating to see what elderly people start to look like, compared to previous generations, where in old movies a guy that’s 40 looks like he’s 65. People are gonna be shocked at what...

    Yes, a man in his 80s can still have good muscle mass

    Damn, that’s sucks that he started that stuff. Can’t blame him. I know 3 people in my very immediate family circle that are on it. I’m sure there’s many other people I’m close with that are also on it that just haven’t shared that info with me I think I’ve heard that ozempic can help with...

    Testosterone Cypionate and Nandrolone Decanoate

    So prior to the 200 test and 100 deca, and 0.5mg of Arimidex 3x/ week (1.5mg total per week) and 5mg of cialis/ day, u were on 80mg of test per week, and 5mg of cialis/ day? That’s a pretty big jump in androgens. Not judging at all, jc if it was ur urologist NP’s idea to jump up test to 200mg...

    Testosterone Cypionate and Nandrolone Decanoate

    Sounds like no changes are perfect in ur situation! Glad to hear it! . Hopefully things continue this way. Hopefully u notice no changes to all things above, and continue to get a bit more joint relief in the upcoming weeks Did u start test c and cialis at the same time? I’m curious how much...

    High SHBG/Low oestriadol

    High SHBG and low free T is a tough one. I’m a health freak, and I’m ALL about figuring out and treating the root causes to issues, instead of using meds as bandaids, but when I was 26-27, I had a SHBG right where ur is, a total T around where urs is, and a free T right around where urs is. I...

    Any advice?

    Yup, couldn’t agree with this more. Would definitely focus as much as u can cutting out gluten, and all grains in general, if possible. Other two things that should make the biggest difference is cutting out dairy, unless it’s raw, unpasteurized, unhomogenized, and from grass fed animals, and...

    Any advice?

    So I would personally feel like sh*t with ur free T level. And I did when I was 27 and had to go on TRT. My free T level was a bit lower than urs, but not by a ton. But on TRT I found that I need a free T level way higher than urs is at currently to feel good again. Not saying to go on TRT...

    Injectable Progesterone SC may not be the best route of administration

    From my understanding, and how it’s been for 99.99% of our evolution, is glucose has been the backup/ alternative fuel source, and isn’t as healthy of a fuel source for all the functions of the body, as ketones are, almost like a dirty fuel source, if u will, so the body tries to use the glucose...

    Injectable Progesterone SC may not be the best route of administration

    everyone’s goals in life are different. At the end of the day, everyone should eat whichever way suits their goals and lifestyle in a way that leads to them having the most happiness in life that they can have. Adding carbs back in clearly makes Paul happier, and allows him to better fulfill all...

    Testosterone propionate supposedly the best ester?

    Wow. I thought 500mg/ day was him kind of going off the rails. Not sure what his rationale for 700mg/ week could be. I’ll have to catch up on his vids when I get the chance

    Testosterone propionate supposedly the best ester?

    Is he really doing 700mg/ week now?? And ya the guys that need 200mg/ week, or higher, to feel and function optimally, on HRT, are going to be the outliers, from what I’ve seen. Seems like the hefty majority of men function optimally on around 75-150mg/ week. Obv that’s generalizing, but...

    Testosterone propionate supposedly the best ester?

    Haven’t watched this yet, but what happened to him doing enanthate? And when ur dosing of an AAS is higher, while using a fast ester, even when levels dip, they’re still gonna be on the highish end, so I would assume that spacing say test prop out EOD, when using very high dosages, would be...

    Injectable Progesterone SC may not be the best route of administration

    It’s the opposite my friend. Go checkout lifelong carnivores. U’d be hard pressed to find people in their 80’s and 90’s with more energy, and that are more metabolically healthy, than lifelong carnivores. I actually challenge u to find me a person that’s doing carnivore, or the lion diet, that...

    Injectable Progesterone SC may not be the best route of administration

    Thanks for chiming in. So first thing, and I think u’ll agree with this, a ketogenic diet cannot be compared to a carnivore or lion diet. They’re more different than they are similar, imo. I personally haven’t seen many examples of someone doing a ketogenic diet successfully long term. But I’ve...

    Injectable Progesterone SC may not be the best route of administration

    Yes, the body still requires some glucose, even while in ketosis. This is why the process of gluconeogenesis exists, and why a person in ketosis, consuming no carbohydrates, will still have a healthy blood sugar level. Fact is, the brain runs better on ketones, mitochondria perform better on...
