I am pasting this from another conversation I was having.
For me, I like Prop over longer esters for the following reasons:
1. Estrogen management is significantly better (for me) with Prop than longer esters. I still have to take 0.25 mg anastrozole 1x per week, but the subjective symptoms of high estrogen are vastly improved. Though I do not have clinical evidence that E2 is lower on Prop vs longer esters, my experience has indicated that it may, coupled with the fact that estrogen follows T levels in TRT. So, as your T levels are likely to fluctuate on Propionate (even with daily shots), your estrogen will go down along with T levels. The benefit is that some of the subjective symptoms of high estrogen may be due to estrogen being held too high for too long.
2. Water retention is much less with Prop (one of the key reasons that BBs use it precontest over longer esters)
3. Mental well-being is greatly enhanced over longer esters. My mood and attitude are simply much better on Prop.
4. I experience stomach issues with longer esters (i.e. bloating and irritable bowel symptoms). I do not have these symptoms with Propionate.
5. For me, it is significantly easier to dial my protocol in. I am the kind of guy who does not do well on a regimen where i take the same amount of T on a regular basis. Most days I like to take 30 mg of Prop daily, but there are some days where I feel my test is too high and I simply drop it back to 25 mg of Prop and feel the positive effects of slightly lowered T in the same day. So with Prop, the beauty is you can adapt your protocol on a day-to-day basis.
6. Daily prop shots allow for greater T fluctuations than ED or EOD cyp shots, which I enjoy. Controversial to most opinions, i feel best when i take a dosage of T that brings my levels to supraphysiological range (~1200 ng/dL), then allow my levels to come to physiological range again. With Prop, I can accomplish this every single day without my T remaining in a supraphysiological state for too long. So, i get the physical benefits of getting my T into a supraphysiological range close to my workout, but reduce side effects by allowing it to not remain in that state for too long. By the time my next Prop shot comes around then next day, my T levels have been back in a physiological state for quite some time relative to the supraphysiological state.
