    New to TRT. Received first labs. Concerned and need help.

    While there may be other causes, these symptoms are very common for older men (the mid-50 doldrums!). It sucks but its the unfortunate reality of getting older. If you find the solution, let me know.

    Pain after subq injections

    For subq, most use much thinner gauge needle of 30 or 31 with short length of 5/16. Injection in belly fat https://www.excelmale.com/threads/daily-subqers-5-stars-for-bd-ultra-fine-insulin-syringe-31g-3-10cc-5-16.24643/

    Giving up on TRT after 5 years

    Respect for the rant and for being honest with yourself. I too have questioned many times whether TRT is worth it and have quit on several occasions only to return for some reason. I think a big part of it is general dissatisfaction with life after 50. For me, TRT has been neither the cure nor...

    TRT Dose question

    Cialas/viagra targets ED - i.e., the mechanical aspect. Whereas lack of libido refers to no interest in sex - i.e., the mental piece. You can have one without the other.

    TRT Dose question

    It is confusing because most of AAS articles appear to refer to TNE as oil base (sometimes just referred to as "Base) whereas Suspension refers to water. Either way there is no ester, but the two can be different in terms of absorption rate and PIP.

    TRT Dose question

    Same exact experience here. At top of range, I have sub-zero libido if that is possible (at least pre-TRT I have occasional flashes). I have mid-high SHBG of 40-45 I continue to be jealous of guys who experience raging libido at supraphysiologic levels. If only...

    TRT Dose question

    I am a daily low dose subq guy and have found that anything over 6mg TE daily will result in early AM awakenings which leaves me feeling shitty rest of the day. I am currently adding 2mg TNE to my daily base of 6mg TE to provide a morning spike. The fast acting TNE is out of the body by...

    TRT Dose question

    Are you having trouble sleeping both peak and trough day? IM or subq?

    TRT Dose question

    Good news that you are feeling better. Are you still experiencing crappiness day after injection? Are you going to stick with 1x per week shallow IM?

    HCG induced aromatase down regulation?

    HCG causing drop in E2 - you and @FunkOdyssey need to switch places :cool: (see thread below). Joking aside, I've never seen anyone on this forum experience lower E2 from HCG. I am a low E2 guy about to add HCG (Pregnyl) to my low dose regiment. I will let you know if something similar occurs...

    Building a TRT protocol around hCG

    So are you officially done with the HCG? Or will you adjust and try again?

    Building a TRT protocol around hCG

    Appreciate the results @FunkOdyssey . That is quite a jump in E2. Why would the bolus from larger, presumably less frequent dose improve the disrupted neurosteroids verus daily?

    Experiences and Questions: Personal Experiments with Oral Native Testosterone Base & Enclomiphene (TRT+), Testosterone Propionate, HCG and more

    Most definitely. I keep a TRT journal and have had quite a few entries about glorious days following TP increase. Then leveling out to point of emotional blunting. Its a tricky balance. One suggestion - don't track day-by-day. Too many variables at play.

    Pharmacokinetic Profile of Testosterone Suspension: A Case Study

    So in theory that would bump you bump to TT 800? I see a new product in development! Speaking of fast acting T, a little goes a long way. When adding TNE (oil based) to my daily TE protocol, I have noticed that 2mg TNE seems to my sweet spot for a morning spike, subjectively speaking. I...

    Building a TRT protocol around hCG

    Damn that is disappointing. I was inspired by this post to order some Pregnyl from Defy. Any comments on other areas such as sleep, mental cognition, energy levels, athletic performance?

    First set of Follow Up Labs since Starting TRT. Looking for Feedback

    Congrats you've just prescribed 1.7x the levels of a healthy young male! That dose would put me at around 1200 TT In the end, its a helluva lot easier to titrate up then down. But who are we kidding with this debate - the elephant in the room is that clinics are always going to over-prescribe...

    TRT Dose question

    I remember envying your success on 1x weekly 60mg. Loved the simplicity of it. Since you seem to do well on it other than first 1-2 days, I would agree with some of the other posters to a modest dose reduction with moving to 2x weekly to blunt that peak.

    Still trying to figure this out - 120mg to 100mg to now 80mg - what a rough week

    If it were me, I would ditch DHEA until you dial in your dose. Many TRTers including yours truly feel shitty on DHEA supplements.

    I’ve gave in and started a cycle after lots of TRT frustration. Can I PCT off altogether or back on TRT

    You've already identified a potential culprit other than TRT that could be contributing to your issues. Overtraining can hit you hard - shitty sleep, general malaise, wired but exhausted feeling, etc. I have been guilty of this many times. As you get older, its very easy to overdo it...

    First set of Follow Up Labs since Starting TRT. Looking for Feedback

    Case in point - my last blood panel on 7.5 mg daily = TT 755 / FT Verm 15.6. There is a 100+ thread on another forum about guys on TC/TE 10mg daily (70mg per week). The majority of them are top end of physiologic range or over. And these are bodybuilder types...

    Building a TRT protocol around hCG

    Are we talking about Pregnyl pharma brand name HCG or compounded HCG? From the threads I've read here, it sounds like most are having more success with Pregnyl

    Any Testosterone Propionate Compounding Pharmacies left?

    Yes even 3.5 days too much fluctuation for me. But if you feel relatively smooth on 3.5, then low dose daily TNE or TS might be a nice kicker in the morning. Let us know if you try it out

    starting injections soon a little nervous

    For intramuscular injections into delts, you want 1/2 or 5/8 as @FunkOdyssey mentioned. I use 30 gauge 1/2" ones while other use 27 or 29 gauge. For subq in belly fat area, you want to use 31 gauge 5/16 needles. You can't even feel it. I recommend these ones...

    Does anyone else have zero libido without HCG?

    Can you provide details on your TRT and HCG doses and frequency? How long before libido showed up on HCG?

    Any Testosterone Propionate Compounding Pharmacies left?

    I recall several posts of guys feeling better on 1x weekly injections. I have tried every injection frequency under the sun, and always revert to daily injections. I found 1x weekly or even 2x weekly too much of a boom-bust cycle. Just shows yet again that doses, frequencies and esters are...

    Kyzatrex - sudden emptiness feeling in head

    How about using Kyzatrex 1x daily to create a morning spike while maintaining a base with daily injections of TC or TE? I am experimenting with something similar using TE + TNE for the morning spike.

    Any Testosterone Propionate Compounding Pharmacies left?

    In theory yes and it sure felt that way for me. I am currently experimenting with using daily Enanthate injection as a steady-state base followed by separate TNE injection to create a morning spike - similar to the TE/TP blend that our own @Cataceous pioneered. So far the TE/TNE feels very...

    Any Testosterone Propionate Compounding Pharmacies left?

    There is much debate about that, but based on my experience TS is faster hitting than TNE. In fact, I am subjectively feeling even small doses of TNE 2mg peaking at 2-3 hours with effects well into 6-7 hours post-injection. Not ideal for maintaining HPTA, but good for creating daily spike.

    Pharmacokinetic Profile of Testosterone Suspension: A Case Study

    Fascinating! I wondered whether this possible. You are truly a mad scientist. On a related point, why don't pharma companies use smaller crystals for Suspension? If they could, would it help dissolve the testosterone in water? Or is that why there is TNE oil-base as alternative? I would...

    Any Testosterone Propionate Compounding Pharmacies left?

    I have tried 2x day prop. Was better than 1x day prop, but not huge difference. If you are willing to inject 2x per day with fast acting T, I have been experimenting with TNE 2x day. Much more noticeable spike (in a good way) than prop and deeper trough at night. The tricky part is that TNE...

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.
