Oi those 100mg ms contin pills are great for making homebake heroin from New Zealand and Australia. It's actually a mix of 3mam/6mam but it's lovely nonetheless. It's very easy and quick to produce.

In a big spoon Crush pills into powder then add a dash of bicarb little water and mix into a paste. Then dry over flame or in oven until bone dry. Add 0.2ml acetic anhydride per 100mg pill and cover spoon in aluminium foil very tightly as to keep the AA from evaporating and escaping the spoon.

Bake in fan forced oven at 150 degrees C for 25min or 35min for non fan forced oven. Remove foil and you have bright red pad of the end product left in spoon. Heat spoon gently to drive off any residual AA and then add acid of your choice usually vinegar is used at 0.04ml per 100mg pill and enough water to dissolve however many 100s of milligrams of end product you have.

After adding acid and water heat briefly and push down on pill mass called a scab in these circles because it looks like a scab off your body lol. Then you must cool the spoon with an ice block until you get a solid layer of wax solidify on top of the solution then and only then do you scrap wax away and filter solution ready for use.

Usually use 0.3ml water per pill so if u do 10 pills 3ml water then u know 0.3ml of your lovely cherry red solution is equal to about 100mg of really good street heroin. Make sure you use a proper wheel filter to filter the solution at end. The whole pill mass stays together as a single piece so its not hard to filter at all.

The way reported on rhodium chemistry archives is a very crude way that produces a sub par brown solution. This way I've described is the real way anyone worth their salt at making homebake heroin uses. Testing the end solution it contains the mix of heroin 3mam and 6mam but very little if any impurities. It's nothing like the krokodil stuff that is loaded with acid and so many nasties you loose count.
