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

    Thanks madman yet again for a very comprehensive answer. It’s very much appreciated. Judging by the paper you sent the idea of a 4/5week PCT won’t be very likely so plan will be to follow the timeline in that study with bloodwork around week 12. Not sure if there’s test gel available without...

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

    Thanks for the reply. Sounds positive and that there may be life after TRT as a possibility I often wonder whether my HPTA is just fried altogether. I’m finishing this cycle around 3rd week in August then going to attempt PCT to achieve a natural baseline and re-evaluate after a few months at...

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

    Why did you do the 2 months off? Was that just to restore some normal function? I think I’ve been over training as was on a mission to try be in good shape for turning 40 in a few weeks but hit burnout which set the whole process back around 2 months. Aside from that though I’ve had a poor...

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

    I’ve read through that but again the focus seems to be mostly in regaining fertility. I’m essentially looking to see if the end of this cycle would be a good time to just come off TRT and how that could be done safely and effectively. As per the end of any cycle there is always an expected crash...

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

    Hi Madman thanks for taking the reply, it was actually your advice that allowed me find a balance with previous issues so thanks again for that. I’ve got 3 kids and no intentions of adding any more under any circumstances so fertility has no bearing on my life thankfully. I was essentially...

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

    So after a long frustrating process with TRT and managing side affects with little benefits I found a kind of tolerable middle ground after some kind advice from members on here. Was doing 10mg test prop subQ daily with 250iu hcg. This made the side effects of worsening ED issues etc a little...

    ED issues with TRT absolutely lost and local doctors dont seem to have any answers.

    So quick update on progress. Been using subQ daily test p at 10mg and things seem to be going well. Emotions are stable, cognitive function is stable, erection quality has improved but still need vardenafil for full erection. (Believe now this isn’t related to TRT but think the previous issues...

    ED issues with TRT absolutely lost and local doctors dont seem to have any answers.

    Was it nhs prescribed TRT or private? Why did you come off? I’d be wary of the nhs use of the word normal for levels as they are very reserved in my experience. Did you use a pct to come off the TRT? There’s far more experienced guys on here that may have an answer for you but I’ve always found...

    ED issues with TRT absolutely lost and local doctors dont seem to have any answers.

    Yeah defo don’t tolerate these well at all they always lead to a crash and going by what other members have been saying the dosages I’ve been prescribed to date are too high so resulting in E2 rising too high causing issues the AI crashing me. Started 10mg test p daily SubQ this week to approach...

    70% of ED cases are vascular!: The Link Between Exercise, Vascular Health, and Erectile Function: Key Insights from Dr. John Mulhall

    Great video thanks for sharing Madman. Weird how I’ve got TRT docs pushing for higher doses to fix it and also nhs urologist actually blaming the exogenous testosterone for causing it. Its no wonder there’s so many guys completely confused chasing answers in the wrong areas.

    Thanks for taking the time to provide such a detailed answer you clearly know truly how these things work. Wish my urologist had that level of knowledge to be honest. I’ve been referred to a regional urologist and will request the ultrasound you mentioned I have looked for a private company that...

    Hi madman, your knowledge seems mega detailed and reads very well. I appreciate the complexity of ED and cannot claim to have the knowledge required to try and rectify it unfortunately. Is there any other biomarkers in my blood results I should monitor/look at that may hold clues to what...

    ED issues with TRT absolutely lost and local doctors dont seem to have any answers.

    That makes a lot of sense. Weirdly I had hcg from the first prescription but as I started in what’s probably a fairly unusual position having gone from a long steroid cycle to letting it crash to TRT it may have been originally too low going by what you are saying there. Often wonder whether the...

    ED issues with TRT absolutely lost and local doctors dont seem to have any answers.

    Testicular atrophy has always been an issue since starting and the doses of hcg to date haven’t managed to rectify that. It has defo led to additional complications with oestrogen though as found things improved in some ways since dropping it. Haven’t tried daily smaller doses though to be fair...

    Think I’ll go with subq for daily injections as it’s what I’m most comfortable with self administering. I read through your thread, you’ve certainly had a turbulent journey and sad to read you’re still not any closer to an answer on the libido issue. The technical detail of some of the responses...

    ED issues with TRT absolutely lost and local doctors dont seem to have any answers.

    Yeah I’d agree with the less substances the better for both monitoring and health reasons. I haven’t had great results with hcg and feel it’s added to the problem as the best stability has been found without it, that’s why I was interested in why Rotngun was suggesting add that dose at the...

    ED issues with TRT absolutely lost and local doctors dont seem to have any answers.

    Seems logical, can I ask why you suggest such a high dosage over the week of hcg? (Compared to what I’ve been prescribed over the last year) I’m going to try what Ziegen recommended with slightly higher Prop dose with no hcg at all to start as so far the issues seem to come from E2 so from my...

    Hi, thanks for the reply. Yeah that’s the next thing I’m going to try as not an approach tried so far and had some great info provided by another member. Order some test P (which seems to have had best results so far for me) going to wait a week after last shot of E then 17.5mg daily. Yeah daily...

    Thank you for taking the time to explain that. I’m happy to try that approach so will get some P ordered and follow the advice you have been kind enough to provide. It makes a lot of sense, will need to try learn self administered delt injections though if doing daily as my mrs and I work...

    ED issues with TRT absolutely lost and local doctors dont seem to have any answers.

    I think it probably reads much worse than it was as the changes were over around 2.5years but the point stands as felt that way myself with the changes the TRT doc was making. Think when I didn’t respond as expected he was a bit lost to be honest. Interested in what you mean about check DHT I...

    Thanks for the reply. At this stage I couldn’t provide a full exact list but an overview would be as follows. Sustanon as described 0.7ml of 250mg/ml every 7days Sustanon 0.8ml of 250mg/ml every 7days Sustanon 0.5ml 250mg/ml every 5 days. At this stage 250iu hcg twice weekly introduced and...

    ED issues with TRT absolutely lost and local doctors dont seem to have any answers.

    First TRT company started me on 0.7mg sustanon 250mg/ml every 7 days, then went to 0.8mg every 7days. They tried dropping to 0.5mg every 5days but oestrogen seems harder to control on sustanon. Currently running 120mg of twice weekly injections 60mg every 3days. That’s what I was running when...

    That’s around how long I get a lift for when I alter dose, swap ester or change oestrogen management approach then symptoms return. Not sure if that’s a placebo or my body just gets used to the change and reverts back to previous damaged state

    Thanks for taking the time to reply. In your opinion would you say TRT would still be part of the recovery or any ideas on alternative options? Tempted to taper off and use long PCT to try restart to normal at this stage just to see how that feels in comparison

    Long story but thought overview would be best. Major health issue 2020 with oesophageal bleed which was put down to long term steroid use. Nearly died, double blood transfusion and was told to not take any PCT as my body would recover in time (was 35 at the time) over a year later and no...
