    Excess niacin causes blood vessel inflammation and cardiovascular disease

    Yes, the form I take is "Vitamin B3, nicotinic acid"

    Excess niacin causes blood vessel inflammation and cardiovascular disease

    "Is nicotinic acid better than vitamin b niacinimide?" Better for what? If you're talking about the effect on blood lipids, then no, niacinimide will not have the same positive effect as B3 niacin. You need the niacin that gives you the flush; the "no flush" niacins will do nothing for your...

    70% of ED cases are vascular!: The Link Between Exercise, Vascular Health, and Erectile Function: Key Insights from Dr. John Mulhall

    The fact that testosterone levels are of secondary importance in ED mirrors my experience. I developed heart disease early at the age of 42 (I'm 68 now) and it always made sense to me that not only my heart but other areas of my body could also have compromised blood flow. Nitroglycerine for...

    Just Started TrT and am Very Confused

    I'm 68 and started T a year ago with an endocrinologist, somebody who should know about Tth, but didn't. Things didn't work out until I started reading this board in earnest. I found the best for me was to educate myself on what to do and then hopefully find a doctor to prescribe the T for me...

    Excess niacin causes blood vessel inflammation and cardiovascular disease

    "According to the article it lowers LDL cholesterol which we all know is false." Vince, perhaps this is a typo or an error in what you meant to say? Niacin dramatically lowered my LDL, better than a statin that I took prior to finding niacin. The reasoning that I would choose niacin again...

    I'm in my early 40s and my calcium score came back 200 with most of it in the LAD. How did this happen?

    To me niacin is a godsend; I take therapeutic doses that typically range from 2500 to 3500mg per day. I take the real niacin, NOT the no-flush type, which doesn't work at all. I buy it at the vitamin store. I take the regular immediate release, not the timed release product. I got a flush...

    Less than 50 mg of T per week

    I'm one of these layperson guys that does well on a smaller dose, probably around 70mg/week. That puts me in the Cataceous camp of thinking. One concern I've always had is that, acknowledging the ideal of 4-8 mg/day that young men produce and use, it seems likely to me that our pathway of T...

    Doctors tell me I had a TIA . . .

    Thank you Ribeye, I very much appreciate your input and will be vigilant in all my actions.

    Doctors tell me I had a TIA . . .

    I just came from the clinic. They never even mentioned my T use or anything about hemoglobin or hematocrit. They do think it was a TIA caused by a blood clot, but they can't tell me whether it was a newly formed clot, or if it was an existing piece of plaque that broke off and migrated to the...

    Doctors tell me I had a TIA . . .

    Ribeye, you've either been there before, or you're a doctor; I remember at emerg that they did an EKG and a while later they did another one "with 12 leads". My last blood test in November showed higher hemoglobin of 181 and hematocrit at 51.0. Normally, perhaps, that wouldn't cause a blood...

    Doctors tell me I had a TIA . . .

    Thanks Madman. What can be said, I guess the ball is in their court. They'll probably have me reduce my T dosage, which I'll do. Hopefully they won't ask me to discontinue use . . . I'm not going back to where I was pre TRT. I've also been using Niacin for 20+ years for cholesterol control...

    Doctors tell me I had a TIA . . .

    Madman, thanks for the research and excellent reading selections. The Traverse trial is reassuring, but one thing I hadn't noticed before, is the following statement . . . "*The debate surrounding TRT and CVD risk thus far can be summarized as follows: current evidence suggests TRT does not...

    Doctors tell me I had a TIA . . .

    Systemlord and Excelnelg; your points are well taken - there are many possibilities as to what happened and I'll try to see to it that the doctors keep an open mind. For the 5 year period before TRT my hematocrit ran .46-.49 and my hemoglobin was in the higher 160's. My last blood test about a...

    Doctors tell me I had a TIA . . .

    I'm 68 and starting taking T enanthate about 9 months ago; I'm a good responder and do well on 77mg/wk, putting me at the high end of the T reference range. I very much like the effects; I've lost weight and gained some good muscle. Yesterday, while talking to my wife, I suddenly couldn't...

    Test enanthate dosage??

    I take enanthate; 160mg would be way to high for me. I took 84mg/wk before cutting down to 77mg/wk. At 84mg/week my TT was 29.4 (normal 8.4 - 28.8) and my free T was 723 (170-475); I also had lipids that were negatively affected, as well as higher hemoglobin and hematocrit. As you can see...

    Injecting enanthate question

    Hey guys, I've been injecting T enanthate for 8 months now. The first five months were with Delatestryl, then when that was no longer available, I switched to the Hikma brand. Typically, before I start, I warm the bottle in my hand for a while, then I inject the full 1 ml syringe of air into...

    Penile Augmentation: The Good, the Bad, and the Ugly

    Terrifying. Men, if you have your erect 5+ inches then forget about this sh*t. In my experience the vast majority of women care first about your being a decent human being and then a close second in your ability to earn money and provide for them. If you have a shred of ethical morality and a...

    I'm in my early 40s and my calcium score came back 200 with most of it in the LAD. How did this happen?

    Niacin worked for me. My lp(a) was around 110 and niacin reduced it to 40-50; no it wasn't below the normal 30 level, but much better than 110. If interested read Parsons, Cholesterol Control Without Diet.

    I'm in my early 40s and my calcium score came back 200 with most of it in the LAD. How did this happen?

    If you go down the Heart Disease Rabbit Hole, it may be a long time before you come out, and chances are you won't emerge any smarter than when you went in. Books? I've read more than my share in the last 30 years on heart disease, and most made very good arguments that the layperson couldn't...

    I'm in my early 40s and my calcium score came back 200 with most of it in the LAD. How did this happen?

    I was 41 when I started getting pain when I bent over, which would resolve when I stood up after about a minute or so. I dismissed the doctor when he said it sounds like angina. I was fit, never smoked or drank, no steroids, no history in the family. But it didn't subside, so I had the...

    Severe Muscle Pain from Crestor?

    I'm 68, had some severe heart disease at a younger age, blood profile was terrible, had a heart bypass at 56. I've been through the whole statin merry-go-round. I experimented a lot. Lots of side effects and nothing seemed to address all my blood factors. In addition I had a very high Lp(a)...

    "Best" way to increase protein intake

    Okay friends, in addition to eating a little bit more meat in my diet, I've made some other small but significant changes that should add some good protein . . . 1. Instead of 2 scrambled eggs for breakfast, I'm now eating 4 eggs (+13gm protein for the extra 2 eggs). I've also added 2 small...

    "Best" way to increase protein intake

    Wow, starting to feel like I missed the memo and, in fact, grew up on another planet . . . clearly, CLEARLY, I have to take things up several notches in my diet plans. Typically, I would think that if you eat this much you gain weight; you're saying it's just the opposite. A lot to consider -...

    "Best" way to increase protein intake

    Interesting Funkman - took me a while to decipher the code. I buy the Kirkland organic eggs too; you eat two of them, check. Then you eat 5 quarter lb beef patties (just the meat I presume); but I could eat 1/2 or 3/4lb ground beef, that would work. Then for dinner you eat the rib-eye steak...

    "Best" way to increase protein intake

    Hello Madman, as usual I'm blown away with the excellent detail when you respond to my questions, many thanks. I would try to obtain most of your protein from dietary sources such as beef, chicken, tuna, salmon, whole eggs, milk and greek yogurt which would be an easy way to get enough protein...

    "Best" way to increase protein intake

    Hi everyone, got a practical question, not directly addressed elsewhere. I'm 68, and have been on TE since April 6 this year, currently taking 84mg/week. I'm pleased - the waist has tightened and the shoulders and arms are bulking up. Of course I want to help it along. I'm 6'3, 235lbs and...

    Trimix newbie...thought I'd share initial impression

    Well, trimix will be coming my way soon too. I'm 68; the viagra works but it's kind of a 70 percenter (to quote SamtheMan) and that's not enough to get the job done right - it worked out badly a while ago so I'm hesitant to try it again. I would start out with something really low, like 5...

    Bausch Health has discontinued production of Delatestryl® in Canada

    "Here we go again LOL!" Well I agree with the sentiment (except the LOL part . . .) I mean honestly, what's with these guys? First Delatestryl, now Hikma's generic enanthate? It's not as if there's difficulty sourcing the raw materials, I understand T is synthesized from common plant...

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
