    About to Start a New Protocol

    I didn't realize your recent test numbers were on Xyosted 75m 1x weekly. That is impressive how little TT dropped from mid-week to trough. Why didn't you stay on the 50mg Xyosted? Total-T: 1129 (250-1100) tested at mid-point Total-T: 1102 (250 - 1100) tested at trough

    About to Start a New Protocol

    When in doubt, minimize the variables. May want to take a break from Tadalifil while you adjust to new dosing schedule. I have had similar low E2 issues, but never done anything about it. I've read some accounts of guys trying to microdose estradiol cream.

    Shallow Testosterone IM versus SubQ Injections - Lab Results

    Thanks for clarifying madman. Maybe that is why no one talks about it lol. I was thinking about role of lymphatic system after several very strange subq experiences with Test Suspension where I felt physically sick, but did not experience that same side effect with IM. But as you know...

    Shallow Testosterone IM versus SubQ Injections - Lab Results

    Its also about convenience. Guys who are injecting small amounts daily often choose subq because its so easy - 5/16 into belly fat you don't even feel it. That's important is you are doing hundreds of injections every year (and thousands over a lifetime). One thing that get little attention...

    About to Start a New Protocol

    Keep it simple. Split your current weekly dose in two. Your levels are plenty high enough already. Don't mess with HCG until you iron out your new E3.5 days protocol

    Dhea and pregnelone

    FYI, Pure Encapsulations makes a 5mg DHEA capsule that allows for lower dosing

    Updated Labs - Help Please

    For EOD, you may want to keep it simple and just double to dose. If it were me, I would lower the dose regardless of frequency, but then again I don't do well at top of TT range.

    Updated Labs - Help Please

    If you feel better on shallow IM, why not try injecting EOD instead of daily to make it more doable? Some guys seem to like EOD. Also, you may want to reduce HCG. Many including myself feel like garbage on it. Keep on experimenting! (although most would say give it 8 weeks between...

    22 yr Old Low E2, 0 Libido

    Normal range E2 / TT ratio is around 0.3-0.6%. Even with TRT (low dose), I tend to hover around 0.25 - 0.30% so on low side. My TRT clinic was reluctant to suggest using estradiol product because its apparently easy to overdo it. As alternative, they suggested supplementing with DHEA to...

    Starting TRT Soon

    Has your A-fib gone away since reducing dose? Early on in my TRT journey, I experienced a bounding heart for several days while I was at high end TT on trough day. It spooked me so I reduced dose and sure enough the problem went away thankfully. Not the same as A-fib, but just another...

    10 Years on TRT and Only Recent Libido Issues

    The libido issues started on your old protocol? Increasing the dose to supraphysiologic levels never seems to work and can even make it worse.

    Starting TRT Soon

    The beauty of self-administering your injections is that you ultimately control the dose. I am also low dose guy (7-8 mg per day) and have so much leftover T in my vials its kind of ridiculous. You won't need the AI if you start at reasonable dose.

    Injection frequency & effects on other issues

    Most daily guys inject Subq with small 5/16" 31 gauge needles. You don't even feel it. Are you currently injecting IM? Reducing dose usually helps with sleep. Although my sleep sucks even on low dose and I've been on daily TRT for years lol. What is your weekly dose?

    Testosterone Side Effects after one year.

    I am same way - even 8mg of TE results in early AM awakenings. Just a wired feeling with steady state. Regarding the blend, here is long thread. I no longer blend and instead do two separate injections - one TE and the other TP. Same idea. No big deal with 31 gauge 5/16 insulin syringes for...

    Difference between daily IM vs daily SubQ?

    Some guys seem to do well on the higher ED doses, but I am definitely not one of them. From the many accounts I've read, even 10mg of TE/TC will put most guys at top of TT range. There is a very long thread on another forum by a bodybuilder talking about the potency of 10mg per day. If you...

    100 mg week testosterone

    Are you certain you are only injecting 100 mg of TE per week? Sometimes these unusual test numbers are result of new users incorrectly calculating their dose. I say this respectfully because I've been there!

    Advice About Hematocrit and TRT Dose

    Try 10mg daily subq injections (31 gauge 5/16" insulin needles). Quite a forum members have had success lowering hematocrit moving to low dose daily. Many guys will easily hit TT of 700 on 10mg daily.

    Dialed in on Testosterone Propionate, How to Switch to Cypionate

    I now think that TP related anxiety is driven by a surge in E2 more than the total E2 level. Any maybe that is applicable to all forms of short-acting T. For example, on Natesto and other acting nasal gels, I would often experience mini anxiety attacks several hours after the T spike had...

    Testosterone Cypionate vs Enanthate Ester break down

    Of course, there is only one way for you to find out if TU is the answer and that is by experimenting. But it could a long ride down if you later determine that your body does not respond well to a longer-acting ester.

    Testosterone Cypionate vs Enanthate Ester break down

    One disadvantage of TU is that you get locked into a dose level for a longer period of time versus say a short-acting ester like TP which allows you to easily play with different doses.
