It depends on how you mixed up the HCG and if you had 5000/2000IU. If you mixed up 5000IU of HCG with 1ml BW then you would have 5000iu in 1ml. If you mixed it up with 5ml of BW than 1ml would give you 1000IU, and with 10ml BW you'd have 500IU for 1ml.

you are right.. so how to I mix this stuff. I have 2 5000iu amps of pregnyl along with the mixing solution. I know i should only do 1 at a time because of how long it last but i need to know how exactly to mix it without another container and how many units equal 500iu on a .3 slin .

Huh ??

You need how many IU are in a CC to answer your question. If they are pre-mixed, you must certainly know how many CCs or MLs are in those amps.

If they are 5000iu/cc then obviously 500iu is 1/10th of a cc, so that would be 10iu on your slin pin.

i edited my post because i was wrong. its not premixed and i have no experience with mixing. the 2 vials comes with the solvent to mix with but i am unsure how to do this.

It has been my experience that throwing away the mixing stuff in the vials is a good move. Buying bact water and mixing the exact amount you want works better.

I generally use 2ccs of bact water for hcg or gh. This way I have less of the good stuff left in the pin when its over. Just a hang up of mine I guess. When using 2ccs, just double what Stone said, and you will be right.
