Hey all,

So I just took my last test prop shot and it got me thinking a bit about whether you guys think that some of the gear we purchase is under-dosed and what your experiences / views might be on it.

Before I go any further I would just like to state that I am in no way trying to bad mouth any brand or manufacturer and will therefor not mention any names in this thread. I am still more than happy to support the brands which I have been using for my cycle and will continue to do so, I do not want to change brands. I still feel as if the value for money is fantastic.

So when I got to the end of my first Test Cyp bottle it felt as if I hadn't quite gotten 10ml out of the bottle although truth be told at the time I was not paying 100% attention to the exact amount so being one bar extra per syringe does add up and make a difference in the end. So I let it go as I noticed that at times I was over a bit per syringe.

Then I started my bottle of test prop, I calculated it and worked out how many injections I should get out of it and I was the only person handling this bottle, unlike with the test cyp bottle. Now unless I do not know how to read a syringe properly, I purposefully withdraw 1.4ml as opposed to 1.5ml for all of my pins and now that I have gotten to the end where I should have around 1ml of oil left I only ended up with 0.5 / 0.6ml of oil left. It really is not the end of the world and if I was so anal about getting the exact amount of oil for each shot I would have purchased an additional bottle, but still that is oil which should have been there.


Now that being said, it is only my experience with a single bottle which I have been monitoring and it is possible that I have been reading the syringe incorrectly or been doing something silly which I have not taken note of - such as some sort of wastage or spillage somehow. It could have even been a mistake with a certain batch or even just my particular bottle.

However the point of this thread is to see, for interest sake, whether other forum members experience something similar to what I have just experienced? :) If so, do you find it happens on a regular basis or once in a blue moon?

It happens to guys that's just started using steroids, maybe 2 or 3 years in you start to become anal with stupid shit like you are at the moment.

Work on 9ml per vial and you will never fall short. The missing 1ml is school fees. I always withdraw 0.2ml more with gear that's between 50mg to 150mg per ml. Reason for that is it gives me a very accurate ml/mg rate.

I also always buy an extra vial with injectables and with orals I buy extra 50 pills.

Gear that's dosed 200mg+ per ml I always add 0.1ml more

I always work off of 10ml and I minus 0.1ml for every injection I plan to make. Some of the oil sits in the big drawing needles and then gets pulled into the syringe when you want to change needles. That combined with the manufacturers maybe accidentally leaving 0.1 or 0.2ml out? They are only human after all. I usually get a total of 9-9.5 measured mls per vial.

I’ve noticed myself that there’s usually around 0.5ml missing from vials and I get emails about that from others as well.

Since its Friday and I’m not in the mood to be productive I decided to use the equipment from my lab and do some measurements. Before anyone gets excited, I don’t work in a chemical lab, but in an electronics lab. I do systems engineering and programming.

I only had 5ml Syringes and 21G needles (1-inch-long) available, so used that in this experiment.

The purpose of this experiment is to determine the volume of liquid that is wasted when we inject. I don’t know the density of the oils used to make injectables and I don’t have the equipment to test it either.

Luckily I know the density of liquid water is 1000kg per m3 at 4 °C and a m3 is exactly 1000L, so 1kg of water is 1L in volume at 4 °C.

So I’ll be using the weight of water to determine the volume.

The scale I used is accurate to the nearest milligram. (Resolution of 0.001g). The scale's cover was closed for measurements to ensure accuracy, but the cover was opened for the photos below.

1: The first step was to calibrate the scale.


2: Then I measured the needle and syringe together after removing them from their packaging. I also removed the cap from the needle. The combined weight was: 4.169g



3: I then used the needle and syringe to draw sterile water (not saline!!) that I cooled to 4 °C.


4: I tapped out all the air bubbles and squirted all the water out of the syringe. I pressed hard onto the plunger of the syringe to make sure that there was nothing left.

5: I measured the needle and syringe again and this time the weight was 4.265g, so 0.096g heavier.


So in total I lost 0.096g of water that I couldn’t get out of the needle and the syringe’s spout.

0.096g of water at 4 °C will give us a volume of 0.096ml.

Let’s say you use your vial of 10ml to do 5 injections you will waste a total of 0.48ml.

This is a very simple experiment to do, so feel free to test it yourself if you don’t believe me. I tried it twice and the difference the second time was 0.09ml as well.

BTW: PGW overfills their vials with 0.5ml, so if you only draw from the vial 5 times you will still get the full 10ml you paid for.

I do not think test will work if consumed orally?
