Pretty sure you can't actually make HQ X-Potions of Strength, mega appears to be the highest you can get (+61). There have never been any sales of even normal quality x-potions of stats on my server.
I told you exactly what I used to do it. Gryphonskin jewellery melded with TANKING stats. This jewellery is better for TANKING than the fending stuff is, you gain 45 STR 45 DEX and some crit or DET in exchange for about 400hp. I do have a setup with pure VIT jewellery for tanking Twintania, but for everything else, Gryphonskin is better. The Gryphonskin setup gets about 7.9khp in a group with food and the pure VIT setup is about 8.3k. Once I actually get some armour drops (or in 3 week's time), this will easily be 8.5k with Gryphonskin.
3k heals are possible every time you have Berserk up. This is with 8k hitpoints. It wont be every time, but it is often. With Berserk up, I can guarantee 2k, 3k on a crit.
Don't put words in my mouth. I have never said I hit 3.7k regularly, I said it was my current highest heal.
