looking at what the best method is? i have lyophilized versinon in 1mg containers - I know it prefers an acidic environment but what is best to be able to shoot?

I've only used HCL CYCLEON...couldn't say otherwise,but it didn't give me a problem.
straight HCL? what? then portion out an amount into sterile water and shoot? I am not sure I like the idea of shooting HCL IM
Check your pm bro.
I'm going with the 10mM HCl this next time. Even cutting with water when it's in BA is still more sting than is necessary.
and for the lazy - 10mM of HCL for 5ml of water is how much HCL?
4.167 micro liters. I'm assuming you have access to "stock" HCL (12M).Quote:

This is assuming the total volume is 5mL. I mean 4.167uL HCl added to 4.99583mLs water
I can get a pipettor easy enough but I dont feel like it since I get my stuff tommorrow :D - I will probably go with the dilute and put .2cc in the slin pin - good call on it.
It would be nice to be in the position to be able to reconstitute some IGF-1, if you know what i mean ;)Quote:

einstein - what if I am using .1N HCL solution? - thats all I have about -
Easier yet for you then.Quote:

heres some info on how to reconstitution, some agree others dont

and just for kicks - If I want to go with acetic acid? :D
:scratch: Is this some kind of test? :wg:Quote:

That ought to do it.
:hello:
you are my new bestest frieeeeend - can you say frieeeennndd? There! I knew you could :lol: - no I just have the HCL elsewhere and cant get over to it till monday - but I want to start tonight :) so Im running to the store to get my vinegar and run it through my filter :D
and I am having to deal with too much board junk today to try to do the math myself
