You should move this questions lower into the forum past these stickies.  You might not get many answers up here.  I would freeze 2 of those 3 vials.  To the 3rd, add 2 cc of bacteriostatic water.  Now 20 units will equal 1 mg, 10 units will equal .5 mgs.   Load the entire vial into syringes and freeze those.  Once you add water, it can lose potency in the fridge.

I am Hope2Btanned's big sister and we are doing this together. We decided to keep posting logs as long as we are using melanotan II because the logs on this forum have been so helpful to us. Hard to get needles and syringes but eventually asked the pharmacist for a diabetic pack which contains 1ml syringes with fixed needles, medi swabs, and needle/syringe disposers. All too easy but each pack contains only 5 of each so I got 2 to start with and have now just bought another 2. These are the biggest packs available unless you join the Diabetes Association and then they are free for as many as you like (so I've been told). I think you may need proof that you are a diabetic though and I don't want to go there.
 
Day 1   1cc (ml) of BacWater into 10mg vial. Used 1ml syringe to draw up.25mg to inject. Very difficult to read accurately as markings very close together. Each mark = .2 so drew up that much easily but then to guage how much of the next mark is .05. Decided to guess and go maybe .2 one night and .3 the next to balance it out. Injected into right side of "belly fat". Nerves +++, pain 000, effecrs minor, facial flushing almost immediately lasting about 20min. We decided to inject at night after reading about sides of sleepiness. Then slept poorly.  
 
Day 2   Injected .25mg into left side of "belly fat". Again very little sides. Slept badly and had nightmares.  
 
Day 3   Injected early(7:30pm instead of 9:30pm) as family coming to visit. Not wanting to try injecting after a few drinks. Left side belly .25mg - effects, facial flushing lasting about 1/2 hr. No bad dreams but may be due to alcohol.  
 
Day 4   Increased dose to .5mg injected into right side belly fat. A little easier to measure dose when drawing up to .5mg. Facial flushing as usual and nightmares. Zero nausia.  
 
Day 5   Injected .5 into left side belly. Mild facial flushing lasting just a few minutes. Vivid nightmares and slept badly.  
 
Day 6   Out to dinner with friends. Took loaded syringe with me and sneaked off to bathroom. Once locked in injected .5mg into right side belly. Minimal sides. Slept well but had had a few wines.    
 
Day 7   Very tired all day but could be the heat. Again injected .5mg into left side belly. Facial flushing but not immediate like usual. Happened about half an hour later but only lasted as long as usual. Slept really really badly and had vivid nightmares which kept waking me up and I would fall asleep right back into the same nightmare.
 
I have not injected for tonight yet as it is a bit early. I am not noticing any results yet but my sister keeps saying she can see me browner. I think it is just because she knows. My sister started 3 days after I did but has had mostly the same sides except she sleeps well and has noticed a decreased appitite. I did not relate the two until she mentioned it but I have been starving hungry all the time since shortly after I started. Funny, these sides and how they affect people differently.
 
Next post in a few days. I will also post details of our supplier if my sister lets me. She may post logs instead of me so keep an eye out for Hope2Btanned. I am Hope2Btannedbigsis.

My log is becoming too repetitious.  I will join some days together if nothing unusual has happened.
 
Day 13 - 14 - 15 No sides these days. Still not much appatite. Caught some sun and have gone very freckly - not exactly what I was after but I will persevere in the hope that it will blend later.
 
Day 16 Was worried about going to a party because I was staying over. I don't want people to know what I'm doing. Took the filled syringe, needle,swabs and needle disposer with me in my glasses case. At the usual time for injecting I went to the bathroom, did my thing and put the needle in the disposer back into my glasses case. Put the rubbish in the bin - No Problems.
 
Day 17 - 18 Caught some more sun but the weather here is so unusual for this time of year and it is cool and overcast. Normally it is roasting and " only mad dogs and Englishmen go out in the midday sun". I am noticing that the freckles I had are much darker and I no have freckles where I didn't before. The freckle look is not what I signed up for. I think I have a slight tan on my back but my legs are definitely just all freckles. Rather disappointing but I push on. Still no sides except tiredness and lack of appatite.
 
Will not post as much detail from now on just brief descriptions and of course any significant changes to either my freckles or my sides.

This log is great keep it up!
Two things though, is there any chance of some pics of your progress, maybe just your arms legs or stomach if you want to stay quiet...
also I've heard some people who get really freckly then goto a solarium once they've got 10-20 worth of melanotan in them and it evens out quite well, so maybe that'd be worth a thought.
