Could also boost aldosterone levels hence the chronic pump/water retention. My gut gets bigger no matter what the cycle is and that's usally attributed to aldosterone. Eat anything salty and I balloon up, lol.
I've always mixed 1 test with 4ad
or other aromitizing compound so I always attributed any bloating to that, but 1test certainly could add it's own. Never really played with 1AD when it was around.
PP is definitely "wetter" though, but I am not sure if it is estrogen, aldosterone or what's going on because there is a derth of info on it. The mood effects are unreal though.
It could be the whole renin-angiotensin aldosterone thing.... or it could be via some mechanism we don't know. The reason I would stray from the aldosterone hypothesis is b/c of the RAPID strength gains you make while taking the product. This would support increased [PCR]. It could also be a combination of all three.
Honestly when one considers all of this all I have to say is:
How much clinical research is there on these "supplements, prohormones, designer products etc?" And I'm not talking about case studies; I'm talking about Double-Blind Placebo controlled studies monitored by physicians or endocrinologists that know even more than we do on the whole HPG axis. Quite a few of the studies are based on rat models, or other animals, I believe. So if you want to take a product whose mechanism you can research; a product that has a plethora of data on it; and has been on the market and thus been able to evaluated for more than a few months to a few years go with pharmaceuticals.
Also unless you can HPG/HPT axis, and have taken Human anatomy and physiology courses and hopefully some exercise physiology or biochem or endocrinology courses, along with a ton of reading you're not qualified to be taking AAS.
And further you should also have lifted for quite a few years on a regular consistent basis; know approximetly what your metabolism is, what variables and manipulations work for you in the weight room, and not be afraid to bulk, before you should take AAS.
Otherwise you'll be able to make amazing gains just by getting your **** straight.
And this is not a rant; this is knowledge from experience.
