    I’ve had labs done 3 times the last few weeks. Any help/advice on what to do next?

    I wrecked myself by skipping nighttime sleep especially between 4-8am. Because of my work I tried polyphasic sleep etc but it only destroyed my adrenals/endocrine system. For cardiovascular and endocrine health it is important to go to sleep at the same time every day and about the same length...

    DHT Cream as an AI?

    I use DHT derivatives like Mesterelone 12.5-25mg/day(Provironum) and/or Drostanolone Enthanate 10-20mg/day(Masteron) for multiple beneficial effects, one of them being E2 control/inhibition. I can only tell you my subjective experience as I have no labwork done on this. We are permanent...

    Do you like HCG?

    I have gone back to 150IU's ED as it gives me stable levels as with my base level of T. Twice a week or EOD 250-500IU gets me a bit on a too superrelaxed emotional rollercoaster which ruins my workout motivation and aggression.

    Do i need HCG on TRT

    I started TRT 8 months ago without HCG as it looked like it had more negatives at first and I do not need the fertility.(although I have only 2 kids:)) First I had the 30% testicular atrophy which is fine as I do not care about that esthetic, but I started to have issues with ejaculation and...

    Wasted testosterone in dead space in syringe

    Before I got the 30G, 8mm, .3cc syringes I needed to do with 27G, 1ml insuline syringes where the needle can be replaced, so I just sucked out/up the leftover bit with my next syringe the next day...... 0 waste.

    Nandrolone added to TRT to reduce DHT?

    It really depends on how I feel, do I want/need a change. A box of Provinorum has 50x25mg tabs which could be a 50-100 days(did 80). Then I popped a vial of 200mgx10ml of Masteron which could be about 100-200 days. I did a short 4 week run on Stanozolol but although I liked the mental aspect of...

    Nandrolone added to TRT to reduce DHT?

    I like to add a DHT derivative for different reasons to my T, like Proviron, Masteron and Stanozolol but have had no acne ever during my 8 months on TRT.

    Just leaked a bunch of TC down my arm...

    After 8 months daily injecting SubQ with a 30G, 8mm, .3cc I have had no leakage, yet. I did belly, sides and now only upper glutes. I tried delts but could feel the oil in the muscle which I did not like. Now I wipe the upper glute, dart the skin, push the plunger with one hand and pull out...

    Do you like HCG?

    I started adding HCG EOD as it is cheap here($6 per 5000IU Pharma grade). I started with 150IU ED but didnt notice much from it but a 2 day hightened emotional state from E2, so it did something. Then went to 250IU EOD and then a week later upped it to 500IU EOD. I became very relaxed with a...

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.
