You're missing something... 50-100 mg pills are standardized (extract) that have some amount of phytosterols in it but you don't know how much of it is in 500+ mg pills which are simply "just" pygeum bark...
Been busy lately so didn't have much time to edge...
Today (just a while ago) I managed to leak out pretty good amount of precum while edging and doing kegels (squeeze/push)...
First it was somewhat watery (I did have some thick precum blobs just before) and then it started to become more viscous with just slight milky color (probably from prostate or seminal vesicles)... Half of my dick was slimy...
Afterwards I went a little bit over board and accidentally released some sperm while edging but didn't have an orgasm...
I'm happy I managed to learn (to some degree) how to produce precum and still not sure if pygeum helps in my case (been cycling it for year and a half)...
