I am on cycle now, and have had the normal amount of testicle shrinkage and reduction in ejaculation volume. I started taking tribulus 5 days ago, and my testicles are gaining size, are harder (as opposed to soft when they shrink), and my ejaculate volume has improved. I am flat out amazed. This has honestly worked better for me than HCG ever has. No bull****.
Tribulus rocks!
(though I think it is giving my incredible heart burn)
