Good morning Mocha
Thank you for reaching out, hopefully I can be of assistance.
My questions:
1. What is the ideal HCG weekly dosage and frequency?
Usually TRT doctors prescribe between 200iu-500iu 2-3 times per week depending on the person. I would say the average dose is between 350iu-500iu twice per week. If you or your physician do not know where to start, you can always start with a lower dosage and titrate up from there. It has been stated that you do not want to use more than 500iu at a time when taking HCG with TRT
2. I believe I have to dilute the HCG (perhaps add 1-3 ml of sterile water so that the total is 2-4 ml of 2000 IU). This will make it easier to draw small amounts. This is the sterile water I intend to mix – is it OK? (I asked for bacteriostatic water but the pharmacy had no clue.)
Sterile water lacks the preservative that bacteriostatic water has. Therefore the only difference is a decreased shelf life when mixed with sterile water. You may get 2 weeks out of this before it reduces in potency, but since its only a 2,000iu bottle you will use it up in almost 2 weeks. Try to get bact. water for the next one. For mixing, add 2ml of diluent so that 1ml = 1000iu. Then each "10" mark on the syringe equals 100iu of HCG. Easy math.
3. The HCG thread here suggests a 30 gauge needle. Will that not break? I'll think it'll be too thin even for subcutaneous injections. I use a 22 gauge needle for the T injections. Can I use a 27/28 gauge for SC injections?
Any gauge between 31g - 26g will work for SC HCG. 30g should not break in the abdomen when administering HCG. you can use a 29g 1/2" if you prefer a slightly deeper injection
4. Any comments on the T level (950 ng/dl)? I'm getting another test done within a week.
Great level! If you feel good and have no side effects then you are on the mark. Remember that your estradiol is just as important, in addition to checking other hormones as needed (thyroid, DHT,) and don't forget hematocrit!!
