    Can I Make My Own Bacteriostatic Water?

    Since I can't find Bacteriostatic water, I want to make my own from sterile water and Benzyl Alcohol. I have purchased a 10 ml vial of sterile water for injection and already have a 50ml vial of Benzyl Alcohol so this was my plan. To make 10ml of bacteriostatic water I will draw 9.91 ml of...

    HCG dosage- How to calculate it

    Nelson's link or reply didn't mention freezing although I have heard other on this list say they do it, so I appreciate their input as in many cases what was good almost 2 years ago may not be as good today, just saying.

    HCG dosage- How to calculate it

    Appreciate the link, since the information is almost 2 years old, am I to assume then that the storage life refrigerated is somewhere between 2.5 and 3 momths? Also, would appreciate a math check so I can be sure I calculated my dilution and dosage correctly. Marvin

    HCG dosage- How to calculate it

    I am about to undertake my HCG maiden voyage (adding to my TRT regime) and could use help in assuring my calculations are correct. I will be taking 250iu of HCG twice a week (T & Th) as I understand the the math, since I have 5000iu of freeze dried HCG, I will dilute it with 5ml of...

    Clarification on T to E ratio

    Yes, I took these labs on the day of injection and before injecting. At the suggestion of others on ExcelMale I have reduced my Test Cyp from a twice a week subque injection of 50mg for a total of 100mg to a once weekly injection of 75mg. This was based on SHBG being high.

    Clarification on T to E ratio

    That is what I thought but another member posted that a ratio of 27 indicates low E2 so I guess what you are saying is don't use the ratio as a guidline?

    Clarification on T to E ratio

    I feel a little foggy, and have aches and pains that I don't usually have and ED problems with maintaining an erection other than that, I feel better that I did on clomid.

    Clarification on T to E ratio

    I have investigated this subject along with what is considered high E2 to the point that I am confused. Perhaps someone can set me straight. As I understand the T to E2 ratio it is T/E2 and the reference range is 14 -20, I also understand that this is only a guide line as how one feels is more...

    Advice on Lab Results

    I noted that to my last PSA reading in may of this year was 2.0 so I am wondering if this 1.6 increase is due to the increase of testosterone and conversely DHT. I have noticed that my urination stream is weaker than it was several weeks ago and wonder about BHP. I did have a prostrate exam...

    Advice on Lab Results

    Any thoughts on E2 should I maintain the 0.125 mg once a week, stop it until I get testosterone under control or increase it. My intuition is to not mess with it right now, change to the reduced dosage of 0.375cc once a week do labs in 8 weeks and go from there. Hopefully during this time my E2...

    Advice on Lab Results

    Unfortunately, I do not have pre TRT labs the last labs where while I was on clomid at 25mg every day. So on 5/18/2018 E2 was 27pg/mL, Total Testosterone was 987 ng/dL, Free Testosterone was 100pg/ml and SHBG was 59 nmo/L. My Urologist is at least working with me as most of the recommendations...

    Advice on Lab Results

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.
