Side Note - here is an interesting article about past supps. They mention Duchaine and Ultimate Orange briefly. (like one sentence) but the rest of the article is very interesting. About Unipro, champion nutrition, Dan's silent partner in business, etc...

Ultimate Orange was just a high dose Ephedra supp.
I've said it a million times here, the epic retardedness of US supp consumers, switching around doing different PWOs all the time trying to find the most Epic "meth like" PWO, when fucking pure EPHEDRINE is available. WTF are they thinking?!

I loved ephedrine so much I f-ing took it for 15 years straight and it never stopped working.
You could supercharge ephedrine as well, if you wanted to, make it even more euphoric. For example like this.
50mg Ephedrine
Cup of coffee
3 grams of Kratom
100+mg of Picamilon
200mg of Phenylpiracetam (banned by WADA, mostly because it helps exercise in extreme temperatures, it raises dopamine and is a nootropic with very obvious stim effects, helps focus)
And if that still isn't enough, add a little yohimbine. This would be very much as potent as an ADHD drug. NO ONE will try this combo, but if they did they'd say that Vanb knows what he's talking about

If someone here is a huge stim and PWO fan, I'd be curious if someone tried this and told me how they like it. Maybe in combo with the second, no rec, but I'd try it. I don't know if it's worth it to me to order and risk seizure, unless someone tells me they work REAL good...
