    Lab Results - Suggestions?

    Thanks for all the responses. I forgot to mention in my original post that I am taking omeprazole daily, along with a daily multivitamin, iron, vitamin D, fish oil, a digestive probiotic, and ZMA. Based on the results I posted above, what follow-up tests (if any) should I request from my doctor?

    Lab Results - Suggestions?

    Thanks! Any idea if my B12 level of 327 is low? I heard somewhere that it should be around 700 for optimal.

    Lab Results - Suggestions?

    I'm 6'2" and 215lbs. I haven't had body fat percentage done but I would guess I'm somewhere between 20 and 25% (could stand to lose 15 or so pounds around the waist). My diet isn't the greatest......probably to much meat and beer and not enough vegetables. I'm really just trying to optimize...

    What tests should I request before TRT?

    Thanks! I'm assuming this is the same test from ARUP called Testosterone, Bioavailable and Sex Hormone Binding Globulin (Includes Total Testosterone), Adult Male: So if I asked for the test above along with the following, I should be covered pretty well: Ultrasensitive Estradiol - CPT...

    Can Omeprazole- Acid Reflux Medication Decrease Ferritin and Cause ED?

    I currently have acid reflux and am taking Omeprazole. I have read on here that Omeprazole (Proton Pump Inhibitors) can adversely affect Ferritin, cause ED, etc. so I would like to try something else. Can anyone recommend a probiotic, supplement, or other med to treat my acid reflux? Thanks!

    What tests should I request before TRT?

    Thanks! So I have a couple of follow-up questions: 1. Would a doctor even put me on TRT based on the levels from my last test? 2. Should I ask my general General Practitioner run tests again (insurance covers) or should I go somewhere like discountedlabs.com? 3. When I do get tested...

    New Vitamin/Supplement/Nootropic Suggestions

    Thanks Vtail. It's hard to say how much the Tadalafil helps. I would say it has been minor so far but I only started it in the last month or so and forget to take it some days. I also may try taking a higher dose (maybe 10mg).

    New Vitamin/Supplement/Nootropic Suggestions

    I am looking for a couple of vitamins/supplements/nootropics to try. I am 44 male, 6'2", 215lbs, and in decent shape.
