Here is my experience with IV'd methylphenidate. All the others i saw were achived. Let me know if this needs to be moved, this is my first post on bluelight.
Stats: mid twenties, about 190lbs, 10% bf, good health. Drank 2 beers with no noticeable effect prior to this, and am currently on a cycle of Testosterone propionate(injectable steroid), Methasterone(oral steroid), and methylepitiostanol (oral steroid). Dosages are modest if not common.
Drug experience: A lot. Smoked, eaten, injected (IV and IM), rectal. Drug of choice would be cannabis or or any opiate. I have used many stimulants, and have taken oral doses of methylphenidate up to 60mg and nasally 50 mg. Never IV'd, however.
Dose: 15 mg, or 1 and 1/2 10mg methylin pills. IV'd for first time ever.
Prep: I prep as usual, alongside my trice-weekly shot of Testosterone Propionate (150mg, IM). Swab the bottles with isopropyl alcohol, let dry, and use appropriate sized needles to draw with. In the case of the methylphenidate (i will refer to it at MPH from now on), i used a 26 gauge 1/2 inch insulin needle. I crush up 1 and 1/2 pills, and squirt the drawn water into a sterile platform. The water used is laboratory grade bacteriostatic water, which is kinda negated by the crude crushing of the pill i suppose. Crushed MPH is added to water, and stirred. No heating. Insolubles precipitate out. I filter with a micron filter (i have a ton for processing steroids from powder). 1 ML is ready for injection.
12:50 am: I inject the MPH into a vein on my hand. Im a veiny sonuvabitch, so its very easy. I also inject the testosterone into my deltoid muscle. Both sites of injection are swabbed with isopropyl alc beforehand.
12:55: I get a tiny rush.
1:00: The rush increases. Im am clenching my jaw.
1:05: Typical stimulant effects. Jaw clenching, sweating, cold extremities, increased thinking and thought processes.
1:10: Effects have not increased.
1:30: Effects platued since 1:05. Time has gone by quick. It feels like i took 30mg orally after shooting 15mg. I take the remaining MPH (35mg) crush it up, add 3 mL warm water, and take it rectally with a needleless syringe. For most drugs, rectal admin seems the most efficient and safe way. Injecting is not usually safe, due to chemical properties and sterility issues, but the most efficient. It doesnt last long, tho. Im done with this report, as the IV portion has ended. Im sure that i feel much more additional effects from the rectal soon.
THINGS WORTH MENTIONING:
There was a lot of residue/crap that precipitated out and was left in the platform holding the water-MPH mixture. I will assume this is insoluble filler material. No visible solid matter was present in syringe after sucking mixture up from the platform. Since I got an effect from injecting, it is safe to say that MPH is water soluble (i confirmed this beforehand). To what degree i am not sure, it is possible that the saturation point of the bacteriostatic water was not high enough to hold all of the MPH. You will have to consult an outside source for this specific matter - i have a degree in biology, not chemistry.
I VERY RARELY use drugs via IV. If im going to, it will only be pharmacueticals with known dosages/concentrations. And preferably made for injection and sterile. This is the first time i've ever injected a pill. I do however, inject anabolic steroids intramuscularly up to 3x a week for periods anywhere from 1- 3 months, followed by equal length periods of abstinence. I use very sterile techniques, and after a couple hundred shots, i have never had an infection. I also keep a large variety of antibiotics (gram +, gram -, and broad spectrum) on hand, as probabilty states that even with perfect procedure i will eventually get an infection. As for myself, I am in very good shape physically, and have a very healthy diet for bodybuilding and health purposes.
Im going to go ahead and say that while effective, injecting MPH is a bad idea. Curiosity got the best of me, but i will not be doing this again. Stimulants are not really my cup of tea, anyway, due to the aweful comedown and anorectic effects. Speaking of comedowns, i will say that coming down from MPH is usually pretty harsh, especially in larger and/or prolonged dose and usage. I have literally sat in a chair and stared at a wall for 2 hours on a really bad comedown, feeling empty, raw, violated, and overall dysphoric. To battle this TERRIBLE feeling, i make sure i have benzodiazepines and/or opiates for the ride down.
Once the comedown begins, i have 2mg alprazolam for the dysphoria and to aid in sleep. I will probably drink a few more beers at that point, also.
