This is my two-week report on vaping methylcobalamin (MeCbl) using an e-cigarette delivery device. Thanks to all and especially
@bluewhistled for getting me started on this. [4]
The basic question I was trying to answer, first and foremost, was: is a pulmonary (inhalation) delivery of methylcobalamin effective? How effective?
In addition to studying various online sources, I have recently spoken to a number of doctors and pharmacists about methylcobalamin, and how it is processed and tested in the lab. I am not an expert, but I do know more than I did the last time I posted.
Regarding vaping with e-cig: I've learned enough about the ins and outs of using this particular vaping delivery mechanism over the last two weeks for a seperate post, which I can provide later if there is sufficient interest. I believe my results will cross vaping devices of various sorts, and I am interested in other pulmonary delivery mechanisms.
MY SUMMARY CONCLUSION: vaping methylcobalamin can indeed be as effective as injections, in terms of absorption, while it is more controllable in terms of achieving steady state. The impressive efficacy of vaping MeCbl has forced me to reevaluate my previous assumptions about my absorption of sublingual tabs.
In short: yes.
EXPERIENCE WITH MECBL: My basis for comparison of MeCbl in my system includes: tabs (slow-dissolve sublingual to chewing), lab-compounded nasal spray, doctor (and self) administered injections, both intramuscular and sub-cutaneous. My fastest and most noticeable reaction was my first intramuscular injection, which provided me with a sharp peak experience that lasted a number of hours and informed my understanding of what MeCbl can do at peak doses, in my system in particular.
MY MATERIAL CONSIDERATIONS:
1. Potency. If the source MeCbl is of poor or questionable potency, no delivery mechanism will work well. I elected to spend more for verifiable compounded source materials, in order to remove any question of potencency as a variable. The lab I used has third-party testing overseen by the FDA, which is as verifiable as possible. I also spoke at length to the compounding pharmacist, who has done experiments with MeCbl to better understand its potenency over a range of conditions. (Regarding MeCbl suppliers mentioned earlier on this thread: I pursued contact with all of them via email and phone regarding potency and none answered.)
2. Sterility. Lungs are highly vulnerable to infection, more so than mucosa or stomach. If inhalation therapy is as effective with regards to potenency as injection [1], that implies anything growing in the source materials will be similarly effective -- not a good thing. Given the month-long cough that I finally shook in September and my subsequent bronchitis, a lung infection was a risk I needed to minimize. Again I elected to spend more for something that came to me sterile so introduction of possible contaminant was less likely. (Online distributors mentioned in this thread also did not answer my requests for information about sterility, but logic tells me there is no way, at those prices, that their products are sterile.)
3. Additive-free. My 24-hour test-run using MeCbl nasal spray with the vaper produced both noticeable positive MeCbl effect and also a negative unpleasant brainfog that cleared up when I stopped. The two additives in that compound which I theorize one or both of were responsible for the brainfog, were trace amounts of benzalkonium chloride (preservative) and sodium hydroxide (PH balancer). While one pharmacist told me these were probably fine for inhalation, I decided to be conservative in my assumptions and use an additive-free compound. Again, I wanted to remove as many variables as I could. Without preservatives, of course, sterility becomes more of a concern.
4. Base liquid sterility. The vegetable glycerin, propyline glycol, and distilled water that makes up the base, while selected with attention to quality, are simply not sterile. While this is a vulnerability, I decided not to try to address it. At first I kept the base mix refridgerated, despite it not coming to me that way, but currently am not. The vaper apparently draws better with the base at room temperature.
5. Refridgeration of MeCbl: USP guidelines do not require refridgeration for sealed, sterile MeCbl containers, which means that MeCbl stays potentent at room temperatures. The USP guidelines say nothing about opened containers, due to lack of sterility. I refridgerate my MeCbl to slow down growth of anything potentially introduced, just the way I would with food.
6. Units of MeCbl & Dosing. My MeCbl comes in 1ML sealed containers, each one containing 20MG of MeCbl. Due to the high concentration and the 20ml syringe I use to draw the MeCbl out of the sealed container, exact measurement is difficult. I estimate aprox .8mg per drop. Additionally, the process of putting that drop into the vaper cartridge is inexact; I assumed lossage in the process. My current estimate is that I have been inhaling between 1 and 2m per day, with some amount over that going into my mouth as what I call "spray" as I work out the best ingredients and mix for the base, or MeCbl "e-juice".
7. Light sensitivity. When refilling cartridges with base and MeCbl, I began by filling the cartridges in the dark -- a tricky process -- until a compounding pharmacist I talked to assured me that a few minutes of light exposure would not degrade the MeCbl. I now keep the syringe and (dark glass) bottles of MeCbl covered with aluminum foil (and in the fridge), but I fill cartridiges in full light. Much easier. I keep cartridges covered during the day, during use, with a two small pieces of duct tape, so I can peel it back now and then to check the level of e-juice.
8. Consumption amount. During this trial period, I elected to consume as much as I wanted rather than limit myself in order to find out what my body would do with a high level of saturation, then at some later point perhaps titrate down. After two weeks, based on use, I estimate that I have been inhaling 1-2mg per day.
8. Inhalation technique. Everything from exhaling first and holding it to puffing it into my cheeks for amusement to attempting to blow smoke rings. Inhalation and hold seems most effective, but I experimented with a range, and even shallow breaths were effective.
9. Base mix. I started with 50/50 VG and filtered water, but have shifted away from that. I am experimenting with the exact mix on a near daily basis because the vaping results are strongly affected by the base. My current formula is 10ml Vegetable Glycerin + 3ml distilled water, and 1 drop Propylene Glycol per cartridge fill.
EXPERIMENTAL RESULTS:
From the first inhalation and through the first 3 to 4 days I could absolutely feel the MeCbl in my system, intensely, having a similar reaction to my experience with injections: in a sense of calm, well-being, being energized and sometimes even hyped. I kept the vaper with me through a number of stressful experiences during these days (driving through bad weather) and it helped me both stay alert and relaxed.
I also experienced a hyped insomnia these first 3 days, similar to my start-up with MeCbl tabs months ago, but found I had more daytime energy than the number of hours asleep would usually account for. That is, I didn't sleep well, but it didn't seem to matter much.
My original plan was to continue to take MeCbl sublingual tabs during this test run to be conservative, because when I last went off the tabs to test my nasal spray, I tanked, regressing to pre-MeCbl state, and it wasn't any fun at all. But it was so clear from day one that the vaping was extremely effective that I stopped using tabs completely.
After day 4, my reaction seemed to even out. The vaping effect was less noticeable and my sleep patterns returned to their previous patterns, perhaps with my sleep improved from previous baseline.
I theorize that about this time -- day 5 -- I had adjusted to the higher dose of MeCbl, achieving something like a steady state, getting through what I now suspect was a new level of MeCbl startup reaction.
Steady state continues. I have become more sensitive to my body's desire for MeCbl; my goal is to stay at a high level of saturation.
SOURCE MATERIALS AND APPROXIMATE COSTS:
1. 20MG/ML in 1 ML vials ($15 plus shipping), requires Rx. McGuff Compounding, CA, USA. This compounding pharmacy impressed me. They had pharmacists who spoke willingly and sensibly about their process and testing. They also offered the best possible prices given my priorities. I found that pharmacy prices for MeCbl vary significantly.
2. V2cigs/VMR products (
http://www.v2cigs.com/): V2 Battery, charger, blank cartridges. Aprox $75.
3. Vegetable Glycerin. Aprox $7.
http://www.amazon.com/gp/product/B0019LWU2K/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
4. Propylene Glycol, aprox $13.
http://www.amazon.com/gp/product/B00I1K0PZG/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
4. Distilled water, aprox $1.
5. 20ml syringe to draw from vial and as applicator; given to me by doctor, so not sure of costs, but should be cheap. (Note each syringe dispenses 25-30 drops, more than the estimated 1 drop per 1ML, probably because the sodium chloride in the MeCbl makes the liquid more viscus.)
COST-BENEFIT ANALYSIS:
Vaping at the quality and control of MeCbl that I am is more expensive than tabs. However, given the unambiguous efficacy and start-up experience I had, I now must conclude that my absorption through tabs was far poorer than I had previously believed.
Previously I had been taking 20-25mg of MeCbl tabs (brands Jarrow and Country Life), dissolving slowly in oral mucosa throughout the day, which at 10% should have gained me absorption of about 2mg, similar to the vaping experience. Given that my vaping during this test run was clearly far more powerful at the same expected dose, I now conclude that my tab absorption was far lower than I thought, likely below 2.5%, achieving something like 500mcg daily or less.
So, to achieve the same level of absorption with tabs -- if that is even possible, which I don't know -- I would need to take 4 times as many tabs as I am taking now -- 20+ tabs a day, which is a full bottle of tabs every 3 days, raising the price to levels comparable to vaping costs.
It's pretty clear it's cheaper than injections.
I estimate my ongoing costs of MeCbl and liquid ingredients, not including the vaping hardware, at some $2-3/day. Given the efficacy and results, I am entirely willing to pay the price of a cheap cappuccino for these results.
I allowed for and expected lossage in this test-run. As I become more familiar with the vaping tech, base, etc., I expect the process to become more reliable and believe I will need less MeCbl, making it more cost effective.
OPEN QUESTIONS:
1. Best base materials and mix to use in vaper. I am still experimenting with the vaping technology base, ingredients and proportions. Different mixes feel, taste, gunk up the cartridge mix, and draw differently. To my surprise different brands of VG also perform differently. My current formula: 10ml VG + 3ml distilled water, + 1 drop per cartridge PG. There are a number of pros and cons between VG & PG, some of which are listed here [2].
2. How much MeCbl for each cartridge fill. Currently using one drop. Because of the high concentration of MeCbl in each drop (and the efficacy) I use one (small) drop per cartridge along with the base. Or less -- as part of my experimentation of the base, when the cartridge starts to empty out, I'll add more base, to mix down the MeCbl. I am not yet sure how much I need.
2. Safety of vaping technology. Recent articles about heavy metals from vaping via e-cig concern me, and I want to know more. The study is based on one brand, which is not the brand I use, which could very much matter, but I don't have enough data to guess; would welcome any insight on this. [3]
3. Long-term safety of process, specifically to my lungs. So far so good, but two weeks is a short time, and my lungs are also part of this experiment. Time will tell.
FINAL COMMENTS:
I have no intention of going back to tabs if I can avoid it -- it is clear to me that pulmonary delivery of MeCbl is highly effective, and as the study indicated, as effective as injections [1]. I do have questions and concerns about e-cig vaping technology, though very much appreciate the transportability of the device, and will be paying close attention to how the industry responds to this recent study. (I contacted the manufacturer of my device and asked; I will relate any response.) I welcome any comments from others using this or other vaping technology.
DISCLAIMER:
All the standard disclaimers apply: this is my opinion and experience only. I have some expert resources now to help me with some of this, including medical professionals, but I didn't always, and when I didn't, I used posts like this one to inform my decisions, so I'm aware that people reading this may be using what I say to guide their own actions, which is why I post my data as transparently as I do. My choices are my own, and I recognize that no external resource can substitute for my own close attention to my body. Your mileage might vary. A lot. I like cappuccinos.
