    E2 Crash Recovery

    I seem to have crashed my E2 earlier this month after anastrozole overuse. My E2 was <5.0 on 11/8, but has since bounced back to 30.7 on 11/16. However, I'm still not feeling much relief, specifically from the ed and low libido. I have been taking clomid and HCG since the crashed however (for...

    Lower E2 = Higher Memory Recall?

    Here is an interesting in vivo study with findings suggesting that lower levels of estrogen in the brain correlate to higher performance in varying forms of memory recall in men. @Cataceous @readalot @Nelson Vergel If a man were to experience brain fog and reduced memory recall while on TRT...

    I need help with Low E2. I’m at my wits end.

    I’ve been struggling with low E2 for the longest time. Started off my TRT 36 mg daily test CYP, 200 IU HCG daily, and 0.0625 mg anastrozole twice per week. Dropped the AI due to low E2 symptoms (mostly achy knees, lethargy, difficulty maintaining/getting erection). Bloodwork showed T = 3100...

    Melatonin Preventing Estrogen-Mediated Gene Transcription In Vitro

    This study (Melatonin blocks the activation of estrogen receptor for DNA binding - PubMed) seems to show that melatonin hinders the action of estrogen-bound estrogen receptors. "The present study shows that melatonin prevents, within the first cell cycle, the estradiol-induced growth of...

    Labs: what would cause my E2 to be so low?

    I’ve come off of TRT, and been off since February. Total t: 534 ng/dl Free t: 62.5 pg/ml Estradiol: less than 15 Does my free T look bad? My whole reason for starting TRT years ago was because of my low free t and very high SHBG. But my estradiol is very low. I have very very low libido. No...

    Opinions on E2 management.

    On TRT for just over 4 years. Lately I've been part of a facebook group that also has a youtube channel: They are all things TRT, however a very strong theme of the group is that NOBODY needs an AI. EVER. So for the past 6 months or so I have not...

    Sustanon EoD injections - experiences?

    Hey everyone, I've just made the switch from 125mg Sustanon E5D to 50mg EoD in an effort to decrease E2 and eliminate my need for an AI (I tend to aromatize heavily regardless of my bf%). For those on this protocol or having been on it in the past, how have you felt on it and what have your...

    Issues with estradiol makes no sense. High estradiol but I feel well.

    So my labs come in, total T is fairly high at 1150, and free T is also up there at 335. Also taking 100mg of DHEA a day. Estradiol comes in at 245. Bottom line at the moment, I feel really good, other than still having some ED issues, that have admittedly greatly improved with the HRT therapy...

    How quickly does Aromatization occur?

    How quickly does aromatization occur? The reason I ask is, lately I've been feeling worse sexually (low libido, ed, dick turtling, etc) the day after my injection. Can aromatization occur this quickly? Or is that I'm throwing off my test/E2 ratio? I've been told by my clinic that estrogen...

    First Lab Post! “Should I stay or should I go?”...would appreciate some guidance. Thank you!

    I’m a 45 yo male, 150 lbs. Prior to starting any testosterone therapy my labs in January 2018 were in range (Total T 601 280-1100ng/dl, Free T 10.43 1.9-27ng/dl), but I wanted to see if increasing testosterone levels would help to improve fatigue. I always had a high sex drive, with decent...

    New Study - SubQ Alledgedly Leads To Lower HCT/E2/PSA Than IM Just Published

    This data was first discussed here a year or so ago when it was released as a poster. It was now just published in a major urology journal. Bascially it suggested that 75 or 100mg of "Xyosted" (SubQ enanthate) each week leads to lower HCT/E2/PSA than does 100mg of IM cypionate. This is a poor...

    Free T is important, what about Free DHT and Free Estradiol?

    Wikipedia says, "The relative binding affinity of various sex steroids for SHBG is dihydrotestosterone (DHT) > testosterone > androstenediol > estradiol > estrone. DHT binds to SHBG with about 5 times the affinity of testosterone and about 20 times the affinity of estradiol." Why aren't there...

    Repeat Bout of Low Estradiol

    Hey guys-- Back in June, I posted this -- suspecting I had high E2 but it turned out (as many of you who replied had suggested) that it was in fact low Estradiol. Once I got my hormones back in a good spot, the symptoms went way. Fast forward to now. Out of nowhere, I started having some ED...

    Higher Estradiol May Help With Aging

    I found this brief clip interesting related to biological aging. I have been embracing E2 by taking boron (6 mg once per day) for a longer period of time than the suggested 2 weeks on, one week off protocol. (120 mg / wk Test-E) Since then I've had excellent results with my hip OA and a nagging...

    High Estradiol Levels

    I just recently had bloodwork done and my test is at 560 ng/dl and estradiol at 49 pg/dl which is about 7 pg/dl above the reference range. I do have some body fat probably around 20-25%. I want to experiment with some HCG and try to get my test into the upper of that range. Should I be worried...

    New bloods in, very high prolactin and somewhat high e2. Would a small dose ai help? Or should I look to cabergoline

    High prolactin, e2 somewhat high, would an ai help? Or should I look into caber. On 100mg test E split everyday injections and added calcium d glucarate for e2 and P5P for prolactin, since starting P5P prolactin has increased from 19-27.8. Also looking to maybe increase T dose to get it into the...
