    Diagnosing sudden hair thinning / hair loss

    Thought I would come back and provide an update here. I most definitely was dealing with Telogen Effluvium. I didn't confirm it with a dermatologist, but had all the classic symptoms. Zero male pattern balding going on, but rather severe "diffuse shedding." The good news is IT's STOPPED...

    Can I take l-citrulline with food or not?

    I've gone periods where I've added it to shakes (i.e., with food) and periods where I've taken in while fasted. I have not noticed any differences at all. For convenience, these days I take it twice per day on an empty stomach. Once when i wake up in the morning. And then again before...

    Got a good protein shake recipe to share?

    For those that are interested in learning everything there is to know about protein, protein intake, and appropriate levels for athletes (bodybuilders, powerlifters, etc.) - this is the best book I've found. It is based on the latest research (and is packed with referenced studies)...

    Got a good protein shake recipe to share?

    I'm as basic as they come. I don't create fancy smoothies or shakes. But I DO care about keeping my protein intake high, so I just have a couple protein shakes during the day. Most of the time, I'm too rushed or lazy to make them fancy, so I try to find GREAT tasting protein powders with...

    Article: New Testosterone Replacement Analyzer App

    Can we share ideas/suggestions/feedback here in this thread? I like seeing what others think would be a helpful feature. I have a couple ideas: 1. I'd love to add bodyweight on the daily assessment. I'd like to see if there's correlation between weight loss or gain and other things we're...

    L arginine for nitric oxide

    I agree with Citrulline being better than Arginine. Everything I've read suggests you are better off just taking Citrulline, that it ends up converting into more arginine than you would actually get from taking arginine directly due to the absorption problems of arginine. (Or something like...

    Reducing/shrinking gyno

    Did you take Tamox with Ana at the same time? And how much Tamox were you taking and for how long before you started seeing results? I developed some gyno on the right side prior to TRT. It's not major, but it's always bugged me. And it does get tender at times. I'd love to reduce it, even...

    Rejected from blood donation because of white coat syndrome

    I just want to say again how awesome this forum is. I'm always learning new things even tangentially or not even related to TRT. And also very cool to have Dr. Saya such an active participant to help in all of these discussions. I'm continually impressed with the depth of his knowledge and...

    Significantly weaker HCG in the summer from shipping?

    My understanding is that there is little concern of harm from the heat in the UNMIXED state. That's why most ship it that way and have you mix it at home, so you can then refrigerate.

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.
