    Intramuscular injections.

    Awesome- thanks SoCalSurfer. I have injected in quads before but don't regularly- is there any issue with hitting a nerve and causing muscular damage?

    Intramuscular injections.

    Thanks Chris- I will chase up some 25G and never look back. I appreciate your help:)

    Intramuscular injections.

    Thanks Chris and Gene, So the 25G or 27G will be fine for TE injections? Do you warm in the hand prior to injection? At the moment I use a 23G 1 1/4 for the intramuscular glute injections- haven't tried SC injections. I have spoken to others and some suggest a lower gauge needle for...

    Intramuscular injections.

    Hi Gene, Thanks for your prompt reply. Yes the needle I use is 1 1/4 inch and I push all the way in. I've attempted the Z-Track but I always get bad (painful) cramps in my back if I try and twist around and use two hands. I always inject with the one hand and use a mirror to guide me. Also...

    Intramuscular injections.

    Hi guys, Is my TRT injection wasted (or potency less) if a spray of blood follows the withdrawal of the needle after administration? I inject slowly, the injection sites are rotated, I use a 23 gauge needle and I did aspirate the syringe prior to injecting the testosterone enanthate solution...

    Can I divide 250mg Primoteston Depot into 2 x 125mg doses?

    Awesome- thanks for the reply Vettester. The sterile vial sounds like the way to go for me- allowing the smaller doses for a more stable T and better controlled E2:) Thanks Eli1947, that was what I thought- once opened and stored the sterility can not be guaranteed. The 10ml TE vials sound...

    Can I divide 250mg Primoteston Depot into 2 x 125mg doses?

    Hi all, The prescription I have for my TRT protocol is Primoteston Depot- a 250mg TE redi-ject made by Bayer (see photo below). I have been advised for a more consistent TT level and better E2 management I should divide the large 250mg dose into smaller more frequent 125mg doses. Is this...

    Can Anastrozole cause nausea and breathlessness?

    Hi Gene, Thanks for the reply. No other pharmaceutical supplementation at the moment and no performance supplementation around training. Initially we tried a few different time frames between injections- reassessed symptoms and checked blood chemistry accordingly- the 250mg TE every 7 days...

    Can Anastrozole cause nausea and breathlessness?

    Hi Nelson, Thanks for the prompt reply. I suspected hematocrit but my Hct is 0.48 (0.40- 0.54). The cardiologist suspected high BP- it is sometimes elevated (140-150/85-90) and I imagine much higher when I train? I have actually just completed a 24 hour BP monitor so will find out the...

    Can Anastrozole cause nausea and breathlessness?

    Hi guys, I have been on doctor prescribed and monitored TRT for the last 4 months. My current protocol includes TE (250mg per week) and Anastrozole (0.5mg twice per week). Lately I feel short of breath and have nausea at times throughout the day- especially during and after training. My...

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
