As stated before, we can't tell you the dosage.
What we can do is explain to you how to read the label and understand your dosage that your doctor will tell you.
200 mg/ml identifies the concentration of the drug, not the dose. What it means is that for every 1 ml of the drug, you will be getting 200 mg of Testosterone delivered to your body. If the concentration was lower, then you would need more volume of the drug to achieve the same dose.
Your bottle looks like it is 5 ml from that picture. What that means is that you have 1000 mg of Testosterone in that vial. (If I'm wrong and it is a different volume, you can multiple the # of mls in your vial by 200 mg to know how many mgs of T you have).
Once you know your dosage, you can divide the amount of T that you take every week or every other week into how many mg of T are in the vial, and that should tell you ROUGHLY how long it will last. For example (and this is NO ONE'S actual dose - this is for showing how to do the math!), if you have a vial that has a concentration of 200 mg/ml that is 3ml in volume, then you have 600 mg of T. If my doctor tells me to take 5 mg of T every week, then I know that I have about 600/5 doses, and it will last me 120 weeks (which is about 2 years). THIS IS NOT AN ACTUAL DOSE! It is a math lesson!
Here are other factors that will affect how quickly you go through the vial:
- Changes in your dosage. The dose you start out with may not be the same dose you wind up taking in 2 months from now. Adjustments in dose will affect how long it takes to get through the vial.
- Wasted doses. Starting out, you might make a mistake with a needle/syringe that results in some amount of waste, if you realize you have to throw out a filled dose and it can't be used (e.g., you compromised the sterility, it has trapped air/blood/etc)
- Slight mistakes in filling your syringes. It's hard to fill perfectly to the line every single time, and while you will typically be close enough to the dose not to matter, the imperfections can add up over doses, leaving you slightly off at the end of the vial.
- Not being able to get the last drop out in the end. It's much easier to fill the syringe with a full vial than an empty one, and it is normal to not be able to get the last dose out.
And congrats!
