    Help a guy to fine-tune his bimix dose

    I finally got bimix that works, I was getting a premix product and not a lyophilized product. It was probably inert from lack of refrigeration. I did 4 units of a 30mg Papaverine, 1mg Phentolamine per 1ml product. I got a chub for about 40 minutes. My "antidote" vial is on backorder so I want...

    Switching From Oral Test to Test Cypionate

    Hello, I tried Kyzatrex at 200mg twice a day for a total of 400mg a day but it only got my total Test to 419. According to their titration guide, I would need 2x200mg twice a day for a total of 800mg a day which becomes cost prohibitive for me. So I have decided to try Test Cypionate instead...

    How many 1 ml doses out of a 10ml vial?

    I am new to this. My doctor sends me a 10ml vial every 8 weeks. Is 2ml wasted in the process of taking eight 1 ml doses or is it possible to get a full ten 1 ml doses out of it? He prescribed 1ml weekly (8 weeks x 7 days = 56 days). After reading it seems smaller more frequent doses would be...

    Natural daily male Test production correlating to TRT dosing......

    From my research I have found that the typical healthy young male naturally produces on average 4 to 7 mg of Testosterone per day... so 7 mg per day at 7 days per week = 49 mg of Test per/wk... Why in the hell was I using 200mg of Cyp per week (actually 140mg Test minus the ester) and...

    Question about supraphysiological dosages of testosterone

    In a January 2012 article, Dr. Mark Gordon discussed supraphysiological dosing: "Gordon explains that conventional medical dosage for testosterone is at 200-300 milligrams per week, which he has shown is far too high! "For example, a typical 25-35-year-old male naturally generates 4-10...

    Questioning both sides of HCG dosing frequency theory

    1: Dr Saya shared the results of his HCG level test study here: https://www.excelmale.com/forum/showthread.php?6133&p=32234#post32234 It seems that the most prevalent interpretation of this information is that a larger dose is more effective due to 1: the increased level in the blood, 2: the...

    HCG 250 or 500

    I've been injecting 250iu eod of HCG with my trt and seems to work fine for me, I see a lot of people do 500 e3d, in the end it's the same amount per week. I would assume that eod would keep a higher level than e3d. Should I switch and why? Thanks.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
