So you're 100% sure it was osta and you have before and after blood with only osta (only)? I've read several people running it without shutdown at this dosage for 4-5 weeks. Yes you can control cortisol but osta has other positive effects to it. Anyways I'm not claiming anything in just tired of people saying it's suppressive because it should be. It's like saying you drink straight liquor 1ml and your vs 1ml of beer. One will obviously get you drunk way faster than the other.
No, I am not 100% sure it was OSTA, no one can be unless they take
their bottle to a lab to have it tested and then use THAT bottle for their cycle. I just have to go on the results and on the research company provided testing documentation saying that it was legit.
I could also assume that reputable supplement companies like Olympus Labs, Elite, Primeval Labs are selling bunk Ostarine. As I have run all of them, and all have noticeably suppressed me while on.
Also people are not saying it causes suppression because it should be. They are saying it is suppressive because it has been proven to be. The lab work you showed here proved that to be the case. It really isn't a question you are going to ask when you are the one who provided the documentation for us to look at is it? The reference you provided showed a 10% suppression of total testosterone, a 20% reduction in free test levels and a 10% increase in estrogen. It definitely shows suppression at 3mg!!!!! Not shutdown, suppression...
Now let's use what we know about how the negative feedback loop and the HPTA work. When androgens increase above normal baseline the negative feedback loop tells the pituitary to slow down production of testosterone because androgen levels are too high. It also increases aromatase enzyme, to start breaking down testosterone quickly, this in tune produces more estrogen, while still lowering testosterone levels.
Okay so that is how that works. Now lets look at the fact that just 3mg a day of osta causes suppression, do you honestly think that doubling the dose is not going to increase the androgen levels further, triggering a larger response from the negative feedback loop. That causes even less testosterone production, but still increasing aromatase enzyme, which then lowers testosterone even more while increasing estrogen levels even further. The higher the estrogen levels the less test production because the body thinks estro is high due too high androgens.
It is a viscous circle.
In the end, if you are planning to finish out your life on TRT keep using Osta in PCT, or as a bridge between cycles. Each time you recover, you will recover a little less by telling the body this lower testosterone level is plenty sufficient for our androgenic needs. It doesn't realize that you are taking in Osta to "feel better" so it accepts a lower and lower baseline of testosterone with each PCT. Even having a high dose of SHBG in your PCT can trick your body into gradually producing less and less baseline testosterone. WHen free levels are high as normal but total levels are not as high the body stops trying to increase production because the free test is high enough. However once you are off the SHBG's free test will lower but total test is the same and the body doesn't see a need for recovery because the total test levels are still at it's new normal.
That is exactly how I gradually put myself needing TRT. Overuse of natty test boosters. It wasn't until my T was in the low normal range that I started messing with hormonal stuff again. Also explains why Osta had a more suppressive effect on me, my levels were already naturally suppressed, so the minor suppression from Osta dropped me into the 300's where libido and motivation dropped horribly for me.
