I wish you luck. I remember when the the 2-c scene was booming in the u.s.(~150/g)and even then, the *t's were always rare to come upon in comparison to c,d,e,i, and p.(b was also harder to find at that time).
That said, never had t7, but t4 was the craziest and most unique phenethylamine visually I have ever researched. It's a long list, but for reference, I've researched extensively 2¢€, D0¢, and me$¢@l!n€, and m€$¢ was the only one visually comparable; but with maybe about 25% of the sparkly-glitteryness of t4. It's hard to describe it, but it was beautiful and truly unique.
On a related note, the H.OT series are 2¢-t pro drugs, but don't appear to be stable enough to be viable for market. For example H.OT-7 degrades back to 2¢-t-7. At least that was the conjecture the last I had heard. Maybe things will change. Chemistry is always evolving.
