    Switching From Oral Test to Test Cypionate

    Thank you aloetard! I will be injecting 0.5ml or 50mg at a time via deltoid twice a week. I've seen both 29g and 28g, 1/2 length, 1 ml syringes online.

    What is the smallest gauge needle you would suggest for test cypionate injection into the deltoid? Would 1/2 inch be the best length? Thanks very much!

    Switching From Oral Test to Test Cypionate

    I took my labs 4 hours after the morning dose which is what the manufacturer suggests. I think that between 3-5 hours after after a dose is when it peaks if I am not mistaken. So the 416 TT and 66.8 FT should have been at peak. The Kyzatrex titration guide says if you are < 460 TT when taking...

    madman, May I ask you what total T and free T trough levels should I be aiming for to tell my dose is dialed in? Thank you!

    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...

    Finally got my lab results back after being on Kyzatrex 200mg BID for a month, no HCG: Prior to HCG mono-therapy: TT = 565 (294-916) Free T = 73 (52-280) % Free = 1.3 (1.5-3.2) SHBG = 57.6 (19.3 - 76.4) After 2 months HCG mono-therapy at 500iu Monday/Thursday (1000iu week): TT = 647 (294-916)...

    Invaluable information madman. I really appreciate it. Makes sense regarding driving up total T to raise Free T as opposed to putting too much emphasis on lowering SHBG. You've given me some hope here. I get my labs drawn on Monday and I'll make sure to take my morning dose 4-5 hours before I...

    Very interesting! I wonder if that is what's happening to me too? Maybe it's more of an issue with the oral T formulations? Thanks for sharing this because it definitely sheds some light on possibly why I am not feeling well on it.

    Thanks Systemlord. I know it is so weird. I thought this would be the perfect solution for me.

    Thanks madman. I really appreciate your advice. I like your idea of maybe just enclomiphene for a bit or cold turkey since I have not been on very long.

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.
