I will keep updating.
One of the experience you would have after sprinting is cold penis and shrinking. But it improves in the forthcoming rest days before you may feel the effects taper off. And this when you again start sprinting (2 days sprinting hard and 2 days rest). So, based on my experience I have given the regime
I do sleep well too and have experienced less panic attacks due to anxiety. This may be because I would have been exhausted after a extensive sprint and harmonies doing Thier work during sleep. Please remember not to over do it, have a balanced sprint regime.
More background on my history:
When I was first faced with side effects, I did do the tests which everyone on the forum recommeded and my doctor always said that free testosterone is the most important. So, when I had my side effects, before I went to andologist, he has order for free testosterone which was more than the upper limit. We have a range of 4-30 and it turned out to be 31 which was very good as per my age. However, the problem was with E2 which should be less < 40 but mine turned out to be 57. That is when the doctor prescribed Tamoxifin for a month but unfortunately the E2 (estrodial) did not reduce and it stayed the same. During the period of use, I did feel good and normal and when expressed the same, the doctor said it would have reduced during usage and rebounded back.
This is when the doctor prescribed Armitose inhabitor to reduce E2 as others harmones are good and more importantly Free T. This is when the problem started as he has prescribed 1mg to be used daily for a month. I just blindly believed and used it for 15 days but i felt horrible during usage. That is when I noticed that some of the member in the forum warned to be careful while using AI. Noticing this I immediately took E2 test along with Free T and I was shocked to see that my Free T tanked to 6 and E2 was not even detectable as anything <10 cannot be detected here. So the report says less than 10 but the worst part is Free T which tanked. Prior to use of AI although I had side effects during the day I used to have nocturnal erections.
Post this my doctor noticing it (low t and low E2 means your HPTA needs to restart) he suggested Clomid, HCG to restart HPTA axis. This just made things worse or kept the same. I was not able to get my Free T more than 10 (range being 4-30). All these taken during 2017 & 2018.
Fed up with use of all medicines (I was worried that these did more harm), I started to hit gym (take ON whey) and some times sprint (never continued long) based on the general suggestions here. However, I used to sleep well but never felt normal. All sideeffects are same except vision and migraine problems.
Even today I repent to have used Armitose inhabitor as I feel my sides are because of this instead of Fin. Although fin has messed up my harmones with high E2 it did not impact Free T (which is critical for normal functioning of penis). I should have tried natural methods to reduce my E2 instead of AI.
I have recently take Free T in Mar’20 after 4 months of gym with moderate exercise and before Covid19 (i.e before sprinting regime). Free T for the first time after long time was above 10 at 15 but way less for my age. The ideal Free T should be in upper range of (4-30) with E2 controlled less than 40. My E2 is however is in control at 16. I hope sprinting improves my Free T.
Also, I started not to follow the forum these months and divert my focus on other things. These also helped to some extent.
I hope this helps and gives a brief of my history on use of meds. I am currently no more using any meds. I even suggest being in Sun for 20 mins early day helps more than taking 60k IU of D3 tablet a week. I am staying a at from but when I tried some vitamin tablets during the sprint regime to check my sensitivity, I was ok nothing drastically made me worse.
