    TRT & Long term Health risks

    Hi All, I am 57 & been on TRT for about (12yrs) I get blood tests every 6 months and have been good on my dose (0.30ML 2x per week). My numbers (hematocrit, estrogen, prostate, etc...) are all fine and I feel well. 1. Will continuing to take TRT cause any problems down the road such as (heart...

    How to replenish low Iron while on TRT

    Well I wont be able to see my doc for another month to go over all my recent blood test. But for the ferritin issue he said I can take ferrous sulfate 325mg (twice per week). He did not mention reducing my TRT dose because he wants my numbers to get better, not worse. Since I am vegetarian, I...

    How to replenish low Iron while on TRT

    Yea I dont blame my doctor though. He didnt tell me to do all three blood donations that I did. He only told me to do the very first one in Summer when my HCT was at 53. I then took it upon myself to continue doing them fearing my HCT would rise if I dont. To my surprise my HCT on my June blood...

    How to replenish low Iron while on TRT

    My Testosterone in Oct was 504. Free Testost (direct) was 15.4 At that time I was on 0.32ml 2x per week. The doc increased my dose slowly to 0.35ml 2x a week to get my numbers up a bit. This new blood test I did this week shows that I am at 620. But this time my free testosterone got a tiny bit...

    How to replenish low Iron while on TRT

    Hi All, How can I replenish my Iron levels? My doctor wanted my hematocrit to come down from 53 back in the summer time. Its now at 49.3. I did 3 blood donations. One in May 2018, Aug 2018 and Oct 2018. My ferritin was at a score of 17 on my Oct blood tests. At that time the doc said to stop...

    Syringe help

    Thx Vince. That makes sense. Maybe I have too much fat in my belly and need to find a little leaner spot. I used to inject subQ into the fat of the upper top buttocks quadrants. I never had any lumps then, but then again those needles were way longer than the teeny weeny 27G 1/2" I am getting...

    Syringe help

    Thanks for your help! I think CVS only had 3ml/25G ones so I was stuck. I needed to get quick syringes while I wait on my syringes to come from Empower pharmacy. I will be getting 1ml/25G - 5/8". On another note, since I was using 1ml - 27G - 1/2" subQ (belly fat area) do you think that is why...

    Syringe help

    Hello All, I was using: Syringe1mL InsulinNeedle Gauge27g Needle Length1/2'' I was getting lumps in my belly fat area since I inject subQ. I inquired about this and was told to use a 25 gauge 5/8 length one instead. They said the 27 gauge isnt long enough and maybe thats why I was getting...

    Is Anastrazole truly necessary?

    Thanks Vince! I am thinking of waiting before using anastrazole. With a score of 57 for estradiol I dont feel any bad E2 symptoms yet and its been 3 months. Perhaps when I up my TRT & HCG, I may start to feel estrogen symptoms arise. Until then, Ill maybe wait to see what symptoms will come...

    Is Anastrazole truly necessary?

    I initially asked him if I can just inject once a week. He said its better to do twice a week. So I have been injecting twice a week for the past 3 months. But what you say makes sense about frequent smaller doses decreases estrogen. I use 27 gauge needles and inject both HCG and TRT in the...

    Is Anastrazole truly necessary?

    Interesting. That sounds better than having to go on an AI. I will first follow his regimen for now of injecting twice a week and monitor myself to see if I notice any E2 symptoms. If they happen Ill follow your advice of closer together frequent doses and get his Ok to do this. Can you tell...

    Is Anastrazole truly necessary?

    My SHBG at the start of my regimen 3 months ago was 17.8. When I did my blood panel 2 weeks ago my SHBG was 18.2. The range is 19.3 to 76.4. My score is low I guess. How does this answer the question of whether I need to be put on anastrazole right away or wait until E2 symptoms pop up later?

    Is Anastrazole truly necessary?

    Hi All, I was on a really bad TRT regimen for many many years (inject 300mg once every 3 weeks). I did not take HCG with my dose either. I was never monitored nor had blood panels. I was taking this dose from 2010 until 2018. I never bothered to get blood panels or check my hematocrit or E2 or...

    Defy Medical Pharmacy Idea

    I am taking Testosterone and have always gotten it from my CVS. The reason I dont want to ask Defy is because im afraid they may decline my idea once I put the idea in their head. They may come up with some excuses to decline my request. I go to CVS and they supply me with my testost. I dont...

    Defy Medical Pharmacy Idea

    Hi All, I am using Defy Medical and they send the prescription to a compounding pharmacy. I dont really prefer this and rather I get it from a pharmacy close by and one I trust. I really dont want to deal with compounding pharmacy delays and refills, being put on backorder and having to wait...
