Excelsior is back in stock i believe. The batches have definitely differed in potency and I’ve even had some bunk tubs that felt very very weak. I’ve been off of it for 2 months and have never felt better. I’m positive Excelsior has an amphetamine analogue or modafanil. Either of which is cheaply sourced causing the lack of consistency in batches.
One of the most solid Pre’s out there I’ve tried in Phase One Nutrition Prephase KO. 200 mg DMHA and 200 mg Eria Jarensis. They recently took out the alpha yo which makes it even better imo.
They also make a nootropic pre workout called Brain Blitz which I actually like better than prephase KO. It’s a very clean energy and the focus is very impressive. I have both those Pre’s right now.
best non Dmha or dmaa pre I’ve had is Alpha Lion Superhuman Supreme. Almost hits like it has exotic stims in it.
You could also just get some Primatene or Bronkaid tabs from a pharmacy. Like $10 for 60 tabs and stack it with 100-200 mg caffeine. Feels almost exactly like Imperial Nutrition Thermal Spark.
Any of the Dark Labs Pre’s are very good...Crack and Flame. I have the Crack Christmas edition which is silly loaded- 100 mg DMAA, 200 mg DMHA, and 300 mg Eria. They don’t mess around with their Pre’s in Poland haha.
The same company that makes Dark Energy started another company called God Status Labz. They have a DMAA pre called krakn and a DMHA pre called Zeus. I’ve heard great things about both.
