Clomid. Body builders use this and I have taken 100mg daily for a week at a time. It can make you emotional but it works. This is what doctors prescribe to increase semen.
Astaxanthin. Solar Ray brand works best. Take one twice daily. I read a patent that had this in hog feed to increase semen and reproduction. It works for humans too. It’s a powerful antioxidant.
Mucanex. Take one pill every four hours and drink plenty of water. This will drain the cowpers . You would think Mucanex would dry you up but it has the opposite effect.
Yes sir, clomiphene citrate. Common for Post Cycle Therapy amongst those of us that use anabolics.
Both Clomid and hCG work nicely increasing the size of a load.. HMG more specifically for increasing sperm count.
