Honestly your stealth lineup is pretty comprehensive, I think it would be a waste to add mixes to the lineup for the sake of it especially when the individual compounds are available. I personally would like to see standalone Mast e and Trestolone. I also would love to see epistane, its the craziest oral I have ever had the pleasure of taking and it's now so hard to find legitimate epistane (i know you don't make this, just planting the seed).
