I have some H comming and I want to do a test on it to see how good it. Is there a method of dissolving or something like cooking back with cocaine? Im new to H so I really have no idea on it and neither do any of my friends.

You put 100mg of the powder into a 1cc synringe and inject it into your mainline vein...

lol nah, its possible, goto Opiophile and search for "Cleaning Street Heroin"...

Also telling folks the type of H it is will help...

This is from erowid:

First weigh out one gram of heroin from the stock you received from your supplier. Place this gram into a 13 x 100mm test tube. Add a few drops of 28% hydrochloric acid until it is evenly damp. Allow to react for a minute or two. Next add 5 ml distilled water, place your thumb over the end and carefully shake to dissolve all that will dissolve into the water. Allow the insolubles to settle. Using a pipette, remove and transfer as much of the liquid to a fresh test tube leaving the solids behind. Dispose of the undissolved remains in the first test tube. Slowly add via pipette, one drop at at time, ammonium hydroxide (water clear household ammonia) until the white precipitate ceases production. Add several more drops at this point just to be sure. Shake gently to be sure that all the solution is evenly ammoniated. The solution should look milky. Now add 100 ml ethyl ether (some kinds of diesel starting fluids, read the label) to a 150 ml beaker. Dump the milky liquid into the ether and stir briskly and allow the water to settle and collect on the bottom. The water will turn clear. Using a glass pipette, remove this water from the bottom of the beaker and dispose of.

Now mix up a solution of 5ml 28% hydrochloric acid and 5ml distilled water and add this to the ether in the beaker. Stir briskly keeping as much acid/water suspended as possible for several minutes. Allow the water/acid to collect on the bottom of the beaker. Using a glass pipette, remove this water layer from the bottom of the ether and transfer to a glass petri dish. Transfer the ether back to its storage bottle for reuse. It will still contain small amounts of heroin base, so don't throw it out. Recycle! Slowly add small portions of sodium bicarbonate (baking soda) to the water/acid solution in the petri until you don't notice any more bubbles being formed. Place the glass on a warm surface, and allow to evaporate. The residue will be diacetylmorphine hydrochloride and salt. Table salt is a by-product of the reaction and will not hurt you at all when injected. Scrape up the residue and weigh it. Yield from one gram of smack (yea, we called it that) would be anything from 100 to 300 mg, rarely more. Place 100 mg of this powder in a test tube, add 10 cc sterile isotonic water for injection (available OTC at drug stores) and heat to boiling. Transfer this liquid while still hot using a syringe (available OTC at some drug stores) to a 10 ml rubber stoppered empty sterile ampoule (available OTC at drug stores).

To use this drug which is 10mg/ml, extract with a sterile syringe as much drug as you wish to use. 10 mg would send me flying believe it or not. 2.5mg (1/4 cc) was usually enough to keep me "happy" and was my normal dose. 20mg was the most I could take safely in my opinion, and was a waste of drug and money. Normally, for most 150-170 lb males, 2.5 mg is more than enough in my opinion. Using heroin in this manner avoids the problems associated with "street use" and will keep your body healthy and safe, reducing the risk of disease and overdosage.

He doesn't sound very confident, though.

I was thinking of dissolving the H into a mix of 20% HCL and water let sit for a bit after mixing than filter and evap and weigh the differenece.
