    Down-titration helped reduce E2 a bit, but it isn't enough. Time for an AI?

    All -- I just got my labs back and thought to share them with you to get your input and advice. I'm going to discuss the latest labs with my Physician this Friday, but I'm thinking of strongly advocating for an A.I. My back and shoulders are a minefield in terms of acne. It's out of control. I...

    Managing sides with daily microdosing?

    Back again, gang. I wanted to know: has anyone found that daily injections (microdosing) help with side effect management? To be clear, I've been feeling great on my EOD protocol thus far (started at 200mg a week, but down to 160mg as of last week). I'm losing fat, gaining plenty of muscle...

    Lab Results 14 Weeks Into Treatment.

    Lab results 14 weeks or so into treatment. My doctor has had me on 200 mg / week since day one. I have low SHBG (10), so by the third week I opted to change my protocol from the doctor's recommendation of 200mg once a week to EOD injections. Energy is stable, libido is going strong, lifts are...

    Low SHBG = lower dosed, more frequent injections. Why?

    It doesn't make sense to me, but I am sure there's something I'm missing. Note, I know that there is a complex relationship here, but I'm looking at this on the surface level. Isn't the "low SHBG = more frequent injection at a lower dose" protocol a bit counterintuitive? For example. Let's...

    This video is commonly linked as an example of a VG injection; however, it doesn't match up with figures I've seen online.

    Video: That, to me, looks to be too far back to be a true VG injection when I compare it to the images, figures, etc. that I've seen in many places. For example: Figure B is the ventrogluteal injection site Self-explanatory Those images are from two different sources. It seems to me that...

    Question on injection method (IM in quads)

    I am doing my second-ever self administration into my quad shortly. My doctor's nurse advised that I should try to "bunch up" some of the muscle/meat in my thigh and inject into that, but that almost feels like it makes my injection more of a shallow IM since I'm not the leanest guy (21% BF) and...

    32 y.o. male starting TRT [200 mg / ml @ 1 mg / wk]

    Hello all. As the title states, I'm starting TRT and my doctor has prescribed 200 of mg of test cyp. / wk. I'm actually going to the clinic tomorrow so that they can show me how to self-administer. Good times ahead (I hope)! I'm not a gymhead these days, but have some leftover muscle from when...

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.
