    My Experiment to Optimize Hematocrit and Iron

    No cognitive symptoms that I am aware of. I have been donating blood for almost 3 years now, and didn't have any iron issues until 2016. I eat plenty of meat every day. 9 weeks after donating, and being on an iron supplement for 1 week - I would think my iron stores would be higher. The only...

    My Experiment to Optimize Hematocrit and Iron

    Plot twist: I just had my blood tested again. This is after donating blood 9 weeks ago, and taking the iron supplement for 1 week: Hemoglobin 17.9 HIGH (12.6-17.7) Hematocrit 49.5 (37.5-51.0) Iron, Serum 45 (38-169) Iron Saturation 14 LOW (15-55) Ferritin, Serum 19 LOW (30-400) High...

    Heart Health Stack

    I think I will buy the ingredients separately. Jarrow looks like a good brand for this. Any other good supplements for hearth health, besides fish oil? Here is that video if anyone wanted to see it: http://princetonhealthusa.com/video_t.php

    Heart Health Stack

    I got suckered into watching an infomercial video online on a product called Vitapulse. The video was well done and the product contains NAC, CoQ10 and PQQ. Doing a little more research online, it seems to be a good stack for heart health - just a little expensive. Anyone have experience with...

    BuzzSaw, check out THIS product. It has a ton of great reviews and Vitamin C built-in. This is what I use.

    balancing low ferritin levels and frequent donation.

    Nelson, I did based on the information I found here. I was taking Quinaprill and switched to Losartan. I have been on it now for about 2 months with no noticeable sides. If you look at my other thread, it seems to have helped reduce my Hematocrit without donation. (I also lowered my test from...

    balancing low ferritin levels and frequent donation.

    Everyone I guess :) I'm trying to figure out the best way to balance low iron / ferritin levels with frequent donation in my thread HERE. I started taking nattokinase (4000 fu), and switched my HBP Meds from Quinaprill to Losartan, based on the hematocrit reducing abilities. My plan going...

    My Experiment to Optimize Hematocrit and Iron

    I probably do. I have a deviated septum and was set to get nasal reconstructive surgery from my ENT Specialist. I had to put it off for reasons out of my control, but I will eventually get the surgery.

    My Experiment to Optimize Hematocrit and Iron

    Here we are not allowed to donate until 8 weeks. But donating every 8 weeks tanked my iron and ferritin over time, and I became iron-deficient anemic. That felt worse than before going on TRT.

    My Experiment to Optimize Hematocrit and Iron

    I definitely noticed a difference, but not feeling bad. I'm not sure yet what my TT is on this dose, I can just guesstimate.

    My Experiment to Optimize Hematocrit and Iron

    Update: Just got my lab results back, 8 weeks after my last results. Looks like I won't need to do the double-red cell donation: Hemoglobin 17.8 HIGH (12.6-17.7) Hematocrit 51.1 HIGH (37.5-51.0) Iron, Serum 94 (38-169) Iron Saturation 31 (15-55) Ferritin, Serum 37 (30-400) Looks like the...

    My Experiment to Optimize Hematocrit and Iron

    I decided to switch my HBP Meds from Quinaprill to Losartan, based on the hematocrit reducing abilities. I've been on it for 3 days now with no noticible sides. I also decided to hold off on the naringin pills, due to possible interactions with meds.

    Comparing my Estradiol Standard & Sensitive Labs

    I've had several labs done, that included both the standard Estradiol and sensitive assays. Thought I would share for those interested in the results: (11/19/13) Estradiol = 46.2 (7.6-42.6) Estradiol Sensitive = 39 (3-70) (12/31/13) Estradiol = 39.5 (7.6-42.6) Estradiol Sensitive = 23 (3-70)...

    I have labs from previous protocols. I wanted to lower it without going too low.

    My Experiment to Optimize Hematocrit and Iron

    Well, here is my plan for now. Let me know what you guys think: I donated whole blood on 10/19 after these labs: Hemoglobin 19.1 HIGH (12.6-17.7) Hematocrit 55.8 HIGH (37.5-51.0) Iron, Serum 87 (38-169) Iron Saturation 30 (15-55) Ferritin, Serum 63 (30-400) After getting BW done before and...

    balancing low ferritin levels and frequent donation.

    Just found this thread. I posted my similar situation in the Testosterone Basics & Questions forum (can't post direct links yet). What is the best way to keep iron/ferritin levels up without spiking hematocrit too high? Only take iron for 2 weeks after every donation?My Experiment to...

    My Experiment to Optimize Hematocrit and Iron

    One thing that I have read that can do this is grapefruit juice, and specifically the ingredient naringin.

    My Experiment to Optimize Hematocrit and Iron

    I've been on TRT for about 3.5 years. I've been on the same protocol for about 3 years: Test Cyp: 80mg every 3.5 days SubQ, HCG: 250iu 3x week SubQ, Anastrozole: .25mg 1x per week, day after T injection. This gets my TT to about 650-750, when I do BW about 12 hours before T injection. I...
