    Hair loss

    Here are a few studies that may be of interest. The actual papers are online free somewhere but the abstracts are pretty good. Basically you can take a tiny dose of finasteride either orally (as low as 0.05mg/day) or topically (0.1ml to 0.2ml of 0.25% solution once daily) and it will block DHT...

    L-Citrulline Supports Vascular and Muscular Benefits of Exercise Training in Older Adults

    1 cap is 250mg citrulline. That’s a long way from the 4-8grams that Mark uses.

    Irritability and anxiety on Testosterone

    I don't trust any T numbers unless it's the Testosterone LC/MS and Free Test ultrafiltration test. I don't even know what test that is now on discountedlabs.com I don't do anything special to get #s that high. I take 5,000 mcg biotin every morning (but not morning of labs) so maybe they're...

    Yes I would get into a routine of lifting or exercising again first. No point in being on TRT if you're just going to be sitting at a desk the whole time. Exercise (weights) would help with natural T and anxiety levels.

    Also note that being obese vs non-obese may affect your levels after injection. Note this study (though on hcg) especially the graph at the bottom comparing im/subq and obese/non-obese: Bioavailability of hCG after intramuscular or subcutaneous injection in obese and non‐obese women

    Looking for advice, opinions and experiences

    Ask @sh1973 and @Cataceous then mix their two answers together :) My opinions which are not always popular...from what you've posted so far. 80mg once per week subq. That way you will be able to notice your peaks & troughs, subq is easier than im, etc. While multiple times per week is good...

    I said subq is way easier :) People have been doing IM for 70 years. Some guys will say the longer the needle the better. There are studies and there is real life. The truth is usually somewhere in the middle.

    You’d be shutdown and might feel worse for a couple weeks. You could just cold turkey it at that point and be fine. Subq is way easier but I think IM is more effective and more predictable.

    Hard to tell with such limited data. What is your hematocrit at?

    Thyroid help

    I thought the main idea of the STTM books was to avoid t4-only treatment. Is Armour NDT?

    free testosterone increase with 100ml cypionate/week?

    I would guess you'd be ~700-900.

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.
