OP,
you can expect a few days of enhanced load size with fenugreek. But it isn't sustained. I don't know if my body adapts to it, builds tolerance, or whatever, but it's not the best bet.
Although I do think you are on the right track. A more specific fenugreek extract called testofen (aka fenutest) did have more sustained results for me.
I think Clomid would enhance load size and male performance. However, outside of pct, I wouldn't recommend using a serm simply for load enhancement.
One of my favorite under the radar products is Ejaculoid by Goliath Labs. This is the best libido enhancer, load enhancer, that I've tried other than formestane or epithio compounds.
