    My trimix sucks, what strength should I have?

    Hey guys, I'm 69, take TRT, and have been using the Trimix prescribed by a urologist, with a formula of 20mg/1mg/25mcg, for a few months now. It works, but not that well. After injection, I'll kinda sorta get a 6/10 erection which can then be manipulated by me to an 8/10, which isn't bad, but...

    Help identifying this arm injury??

    I'm 69 and have been taking T for a year and lifting weights for 8 months now. I like the board members here and hope they can help me with yet another problem. My left arm is my non-dominant arm and if I'm looking at it with a straight arm, palms up, the pain is at the inside crease, but near...

    Does arthritic elbow mean I can't lift weights?

    Hi, I'm 69 and started lifting some weights when I started T a year ago, but stopped soon after. I thought I had started too fast and given myself a case of tennis elbow. I gave it 7 months of rest; it got a bit better so I started lifting again. I've been lifting about 5 months and have made...

    Good first Trimix experience, but questions remain . . .

    Hey guys, I'm 69 and on TE for a year. Been on Viagra about 10 years, but it's really not cutting it anymore. Just had my first 25/20/1 Trimix experience, thank you Nelson Vergel for your excellent instruction. I've always had a good response to small doses of any medication (T included); I...

    Trimix while on blood thinners like Apixaban?

    Hey guys - I'm 69 and have been on TE for about a year, love it. I had a TIA in December and was recently put on a blood thinner / anti-coagulant being 5 mg Apixaban (Eliquis) twice a day, permanently. I saw a urologist a few days ago about beginning Trimix. There's a $300 fee payable before...

    Can an older man still build muscle while taking statins?

    Hi everyone, I'm a 68 year old on Testosterone Enanthate for one year, love the results on body composition. I've had heart issues in the past, with a successful bypass 13 years ago. I've always resisted statins, and have done well taking niacin the last 20+ years. I was doing really well...

    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...

    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...

    "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...

    High blood pressure from Hematocrit and Hemoglobin

    I have searched the forum but haven't found a lot of information, or concern, for the high blood pressure that can result from the thicker blood that higher hct and hemoglobin can give to you. I've been on Trt for about 6 months now (currently 84 mg/week) and my hct and hemo are climbing; I...

    TRT related to Osteoarthritis? Is there life after a Osteoarthritis diagnosis?

    Hello everyone, I'm 68 and have been on TRT about 7 months. I tried TRT with the main aims of fighting fatigue and numerous aches and pains that I've suffered from for a long time. Mostly sore joints, sore back etc. About the time that I started TRT, my hands started hurting, and I have since...

    Do your 5ml vials of T supply you with the correct number of shots?

    I'm nearing the end of my first 5 ml vial/bottle of T enanthate; mine is still the Delatestryl. It looks like I'm going to get about 800mg from the bottle, when the bottle says I should have 1000mgs. Please assume my math is correct (which it is). I take a small dose every 4th morning (34...

    You're past fertility concerns; do you take T alone or add HCG?

    I'm 68, don't want kids anymore, on T monotherapy and nothing else. But should I also be on HCG? I've read that HCG is not just helpful for fertility and the prevention of testicular atrophy, but for a host of other hormonal benefits. Should everyone who starts TTH also take HCG? How many of...

    Enanthate shortage . . . and how many doses from your vial?

    As most of us know, our beloved Delatestryl has its days numbered. I think production stopped, after 68 years, in April. I started T very recently and I'm due to run out of my first bottle on June 8, and had hoped the pharmacist would save me a bottle. I contacted him today telling him the...

    Surprising blood results . . . so is this it?

    I'm 68 and started TRT on the gel therapy on Dec 20/23. I was on that for 3.5 months before it was finally determined that it wasn't working right. I then went on TE injections on April 6, taking a rate of 10 mgs per day, injecting 40 mgs every 4th day (equivalent to 70mgs per week). Only...

    The benefits of low dose T injections . . .

    I'm 68 and have chosen to pursue TRT primarily to treat fatigue, amongst other things. After a bad 3 1/2 month experience on gel (detailed elsewhere), I've finally convinced my endo to switch me to enanthate; my first injection was Saturday. Thanks to Madman for seeing me through that. The...

    Got Test results after 3 months 1% T-Gel . . . very rattled!

    I'm 68 and was diagnosed in December with lower T at 314, hematocrit at 47. I decided together with the Endocrinologist to go with his suggestion of 5gms 1% T Gel, the regular starting dose. Fast forward to my first blood test taken yesterday after applying the gel regularly for 3 months. And...
