Reconstituting And Measuring your GH

This is a
very common question, and instead of retyping this in every PM, I’ll just make
a sticky. This will be applicable to any brand of GH and any vial size.

OK, you
have your vial of lyophilized GH (powder). No matter the brand, you know how
many IUs are in each vial, as that will be noted on the vial. If it’s in terms
of mgs, just assume (estimate) that 1mg = ~3IU.

It does NOT matter how much water (BW or sterile water) you use. I tend to use
more than what most kits include, because this makes it more dilute and means
that you’re less likely to leave some behind in the vial and syringe.

Pick a volume of water to add to your vial….I don’t care what it is. For a
10IU vial, I use 2mL, but between 1 and 2mLs is good IMO.

use a syringe with a 1″ or better yet a 1.5″ needle attached to
reconstitute. Load the syringe with water (BW ideally, but sterile water is
fine, despite popular belief). Hold the plunger so that when inserting the
needle into the GH vial the vacuum doesn’t suck the water out. Once the needle
is inserted, angle it so that the needle tip is pointed at the side of the
vial….not directly at the powder. Now, simply release the plunger and allow
the vacuum force to suck the water out into the vial. Remove the needle and
gently swirl the GH vial until fully reconstituted.

Now measuring….this is much easier than people make it out to be. Just use
this generic formula:

You know how many IUs are in your vial. You also know how much water was used
to reconstitute it (since you just added it). how many IUs do you want to
inject? 2IU? Fine, so be it. say your vial was a 10IU vial, 2IU is 20% of 10IU,
so you simply draw up 20% of the total volume used to reconstitute your GH. If
you used 1mL for a 10IU vial, and you want to draw 2IU, then you simply draw
0.2cc. if you used 2mL for a 10IU vial, you’d draw 0.4cc (since 20% of 2mL is
0.4cc). Most everyone is using a U-100 insulin syringe for GH injections. Each
10IU mark is 0.1cc, so the 20IU mark is 0.2cc, you can figure out the rest.

That’s it….it’s easy, if you think of it this way.


There is a lil more involved so I will just post the method I use:

Here is the red barrons post bro

I have noticed several posts lately wondering about a good method for
reconstituting IGF-1 and a few posts about using vinegar/water to do so. I
originally wrote this post at anabolicmonsterz, but since there seems to be a
reasonable interest here as well, I will post it for those that might be

I began using this method many months ago … mainly out of impatience. I was
out of Benzyl Alcohol, and while I had access to HCl, it wasn’t accessible when
I wanted to begin my Long R3 IGF-1 cycle. I decided to use plain ol’ grocery
store Distilled White Vinegar. I used the following, which has worked out
really well for me….and the feedback I have had from others that I have
shared it with has been positive so far. So here it is for anyone that is

The calculation:

Distilled white vinegar is supposed to be standardized to ~5% acetic acid,
which would make it 850mM. To get it to the recommended 100mM, you’d want
11.76% white vinegar (100mM/850mM = 11.76%). Since it would be almost
impossible to draw out 11.76IU’s, I round this to 12, which is certainly going
to be close to our desired 100mM.

The filtering process:

I use off the shelf grocery store distilled white vinegar. In order to ensure
safety, I filter it using .20u whatman filters. Here is the step by step for
those that may not be familiar with filtering using whatmans. What you will
want to have on hand before starting out is some sterile vials, some .20u
whatman filters, some syringes and needles (I use a 10cc syringe, and .23 gauge
1″ needles), and some alcohol swabs.

(1) First draw up about 10cc of the distilled white vinegar

(2) screw on the .20u whatman to the 10cc syringe (or whatever size you use)

(3) screw on a .23 gauge needle (or whatever size you decide to use)

(4) take your sterile vial, swab the top with alcohol, insert a needle for

(5) Insert your syringe/whatman/needle apparatus and slowly push the 10cc’s
into the sterile vial.

Now you have safe vinegar to use for your reconstituting.

ALTERNATE METHOD – Alternately, you could simply mix your water and distilled
white vinegar before filtering using about 7.5 parts of water per 1 part of
distilled white vinegar. After mixing these together in this ratio, run the
mixture through your .20u whatman as above. You will end up with a vial of
dilutent this way that has the proper PH for use with your IGF-1.


How much water/vinegar you reconstitute with is going to somewhat depend on
which LR3 IGF-1 you are using. Igtropin is shipped in 100mcg vials, which I
usually reconstitute at 1ml(cc) per 100mcg vial (which will make the 10 mark on
your insulin syringe = 10 mcgs). The gropep based IGF-1′s are primarily shipped
in 1mg vials, and I usually use 5ml for these (which will make the 10 mark on
your insulin syringe = 20mcgs).

At any rate, what I do is:

(1) take an alcohol swab and swab the tops of my water, vinegar solution, and
IGF-1 vials

(2) take a syringe with a 23 gauge, 1″ needle and draw out .12 cc’s of
vinegar for the 100mcg vials or .60 cc’s for the 1mg vials.

(3) next I take this syringe and draw out the water – .88cc’s for 100mcg,
4.4cc’s for the 1mg.

FOR ALTERNATE METHOD in lieu of steps (2) and (3) – Just draw out the desired
amount of dilutent from your pre-mixed vial of

vinegar / water.

(4) next i poke the needle into the LR3 IGF-1 vial and dribble this solution
down the side of the vial, avoid any direct spray on the lyophilized powder
until all of the dilutent is in the vial

(5) using a gentle swirling motion, I reconstitute the powder.

(6) I stick the vial in the fridge and it is now ready for use.

Well, I think that about sums it up. Hope this helps anyone who may have been
wondering about using vinegar to reconstitute. I would advise that if you end
up using Igtropin, you seriously consider using this vinegar method. Igtropin
and other dilutents such as BA do not get along well together at all.
