Ran out of time to edit.
I see
Prostaglandine (PGE1) - MOQ 5mg - $65
Phentolamine Mesilate - MOQ 100g - $200
but no Papaverine.
Also *NOT* that it particularly matters but a single dose of trimix is around Papaverine 3mg/Phentolamine 0.1mg/Prostaglandin 1 mcg
So your MOQ's are:
5000 doses of PGE1
1 million doses of Phentolamine
Even for a very large, potentially dangerous, dose of 50 units instead of 10 units, you're looking at 200,000 doses of Phentolamine. I don't think customers will ever use that much phentolamine! If there's any chance you could reduce the MOQ of phentolamine... ;-)
Also P.S. for other readers here I'm scared for anyone who attempts to measure out 50-100micrograms of prostaglandin for a single 10mL vial
Even if your scale has a resolution of 0.1mg doesn't mean it can measure a 5mg MOQ. This is because it has a "minimum weight". For 0.1mg scales that's usually at least 10mg. For 1mg scales its usually at least 20mg. If you try to measure less than that it's basically just a random number.
So let's say you have a 1mg scale and you think you can get away with measuring 20mg so you buy 4 MOQ's of prostaglandin. The solubility of prostaglandin in water is about 1mg/mL so you can dissolve it in 20mL of water. But you need to reduce it to 5micrograms per mL. So you'll want to add 4 liters of water to that 20mL.
Then you can take out just 40mL of that 4L, then add 20mg (good luck again) of Phentolamine to it.
Then take 10mL of that 40mL and put it in a vial and add 150mg of Papaverine to that vial.
Now you've got 10mL = 100 doses of trimix.
aaaand you have 3.96L of water containing $259.35 of prostaglandin. Just go ahead and throw that away. Also throw out the 30mL of water containing Phentolamine+Prostaglandin. You won't need that either. You're also left with 99.98g of Phentolamine raw powder left over that you paid $199.60 for that you can throw out as well.
So, basically no matter what you do, you'll end up with 100-1000 doses of trimix and throw out >99% of your raws (>$400 thrown away). Is it worth it? Well, prescription Tri-mix is around $140/10mL vial. So if you make 4 vials, for 400 doses....I guess you technically save $150 + a doctors consultation fee. Also you have minimum 2 years worth of trimix (can't use it more than once EOD) and I dont know if it lasts that long in water! (and there really isn't a way to make it without water / some kind of true solvent...please dont even try without using a solvent to dilute, you'll definitely get your dick removed in the Emergency Room if you try to just work with dry powder raws at the microgram scale, even using geometric dilution...the particle sizes are not uniform and there will be clumping/separation/sorting rather than mixing)
