    Bryan Johnson, who spends $2M a year for 18-year-old body.

    He looks a bit pale, looks like he could do with a good steak. I think he is also on finesteride, seems healthy enough though despite the fin.

    When is Prolactin too high and what are benefits of lowering it

    I have listened to several Hertoghe vids and he says low GH causes high prolactin and by correcting GH it lowers Prolactin. I’ve never heard that anywhere else though. Anyone?

    Drastic increase in libido - currently multi-orgasmic to an extreme - any experience with this?

    Maybe wise not to analyse it too much, it sounds pretty good to me, if it aint broken why fix it, surprising you have those results on 200 mg every 21 days, you dont say what T your on but for Cyp or Enan thats a long stretch and a big shot. Maybe wise to check levels at one week/ 2 weeks to...

    MWF pinning but feel unstable Sunday/Monday

    TSH is only rough guide , Ft3 and Ft4 are the important ones, also TSH should be tested around 9am, it varies at different times of day,as Systemlord mentioned careful if taking iodine or anything with iodine in it as it will mess up labs for thyroid, in my experience thyroid labs if...

    FUT/FUE Hair Transplant

    They can do a lower hairline that looks natural as long as it’s naturally low ie not too low. The reason they don’t like to do this is that we only have limited doner area so they say keep that for top and crown, don’t waste them on a age inappropriate too low hairline

    FUT/FUE Hair Transplant

    I agree, avoid low hairlines or look ridiculous like Stalone when you get older, youd think with the money these guys have they would find the best, his is a mess and Arny's isnt great either, they took too many FUE grafts from doner area so he has very thin/baldish area behind his right ear...

    FUT/FUE Hair Transplant

    well , I think you have answered that yourself, maybe you have been looking at the wrong transplants, its like plastic surgery , you only notice the bad ones. They cant get 100% density but with dense packing they can give that illusion of density. you dont necessarily need several procedures to...

    TURP: Treating Enlarged Prostate Urinary Issues

    I would try Rezum or the other water ablation first , some say Turp is a bit like using a chainsaw, plenty risk of sides , imotence, retro ejac, incontinence etc , it will get you peeing okay but as for the rest, last resort in my opinion, I had Rezum and researched them all to death. So sides...

    FUT/FUE Hair Transplant

    Sorry Sammy but this is BS. I had 4300 grafts on top and front 13 years and it looks 100% natural, there are no plugs , they just do single hairs on front and maybe 2-3 hairs further back. A good surgeon can do it no probs.

    FUT/FUE Hair Transplant

    I had FUT 13 years ago was on Androgel and it was fine, the Hair docs love finesteride , they will suggest topical if you dont like pills, I think it all gets into bloodstream, maybe less with topical depending on concentration. For sure my hair is better than if I didnt have the transplant, the...

    300mg Test Enanthate every 4 days

    I think I heard Dr Rand Mclean saying in a vid that we cant compare natural production dose of as you quote 3-9mg with TRT, cant remember if he explained why, I think I was on around 9mg per day of equivelent adrogel , got by but not optimal, kept T in mid to low range but FT way low, even at...

    Pregnenolone CRUSHED my libido

    Some feel good on Preg but some like me dont, one Doc said Preg can convert into things you dont want it to convert into and go places you dont want it to go, as Gianluca said best to test before staring any hormones or vits incase you dont need them, I personally like the add one thing at a...

    Hematocrit and TRT. How to have balance.

    3% can give you a bit of a tickle sometimes but many on the COPD sites use it daily, no probs it seems. Mercola is now using 0.5% daily the last time I looked. He is a bit eccentric but I suspect he knows his health stuff, he is extremely careful about diet and avoiding toxins etc to the point...

    Hematocrit and TRT. How to have balance.

    We use between 0.5% and 3% , during worst Covid period and after flights or similar environments its 3% since nearly 3 years almost daily. If I am hibernating then I dont use it. It must be food grade and I dilute it with saline. Its best you do your own research though and satisfy yourself first.
