I got quite constipated while on humaworm so half way through I used Oxypowder to clean things out.
For the first two days it was great, totally cleaned me out. On the third day, it looked like I passed the Humaworm pills undigested. I took the Oxypowder a few hours after the humaworm so watch out.
After that I only took the oxy every few days only 2 pills. After I finished Humaworm, I was regular again.
