    Who does not need to use an ED med?

    What do you think about running test prop alone ( or perhaps test prop/primo, in your case) for several weeks, then hCG on its own for a few weeks? Would T levels be too low on hCG alone, following suppression from the test prop?

    Testosterone propionate supposedly the best ester?

    Does it contain ethyl oleate? Do you think the absence of bb in the 50mg/mL formulation is what reduces the pip so much?

    T Propionate protocol

    Ok please let us know when you get the results of your blood work? Have you tried sub Q shots into the glute fat? That method would be easiest for me to adhere to. Daily delt shots must get old very fast.

    The Olympics Don't Allow Doping. This Competition Will Encourage It.

    I'd be surprised if any athletes competing in the Enhanced Games perform better than the best athletes in the Olympics and that's not because the best athletes in the Olympics are also doping.

    My blood results on test propionate

    That's a very high dose of hCG! It doesn't surprise me that you would experience high E2 symptoms!

    My blood results on test propionate

    Do you take hCG as well? I wonder how adding about 350iu hCG every 3 days would change the way someone on daily Prop would feel.

    My blood results on test propionate

    Ok that explains it then. You're basically nocturnal :) Your blood tests results are unusual for someone on Prop, though. Normally you see a much greater difference between peak and trough levels. How does your libido on Prop compare to other protocol ls you've tried? Are you also taking Cialis?

    My blood results on test propionate

    Why are you dosing before bed and not in the morning? How did you find a lab that's open so late at night to test 25hrs after your dose?

    T Propionate protocol

    How much progesterone cream are you using and why EOD, not ED? Are you also using hCG? I wonder if there would be any need to take progesterone in addition to hCG since you get quite a lot of progesterone from the hCG.

    Is Oral T (testosterone undecanoate) Safe and Effective for Men With Low Testosterone?

    Is oral T basically just testosterone undecanoate mixed with caster oil? I wonder if it would be possible for guys who live in certain countries where it's legal to buy testosterone undecanoate powder to just mix it with caster oil and take it orally via a dropper bottle? This would certainly...

    Anyone try HCG Pregnenolone before starting TRT?

    I've never tried pregnenolone but I did try hCG monotherapy before TRT/hCG and honestly felt better on just hCG. If your low T is due to low LH, I'd suggest starting on hCG monotherapy.

    Best Sleep Supplements

    I have the same problem. I can only sleep for 4-5 hours, then I'm wide awake. Recently, what has worked very well for me is drinking chamomile tea with 2 heaped teaspoons of glycine powder as soon as I wake up. Then go straight back to bed. Don't turn on any devices. Normally within 30 min I'm...

    Trans scrotal testosterone cream application is a game changer

    On the carnivore diet, consuming sufficient calories, my libido was zero! I respond best to a high carb diet. The higher the sugar content, the higher the libido for me. Eating lots of chocolate and sugary foods skyrockets my libido.

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.
