Concerned brew gone wrong?

I recently brewed two batches of Testosterone Cypionate and encountered some issues that I hope you can help me with. This is my first time, so I made a lot of mistakes. However, I used a hotplate mixer and general sterilization practices, so I believe it's okay. I even made my own labels to feel more official.

Batch Details​

First Batch (100 mL Total Volume):
  • Testosterone Cypionate: 25 grams
  • Benzyl Benzoate (BB): 20 mL (20%)
  • Benzyl Alcohol (BA): 1.3 mL (1.3%)
  • Castor Oil: Remainder to reach 100 mL
Issue: I had to discard 40 mL because I couldn't filter it properly using a syringe filter. It was extremely difficult and messy. It was hell on earth to filter this by hand with my nylon 0.22-micron filters (25mm). Even warming to 80°C for a bit proved very difficult. It took me 5 hours to do this as it just dripped through, no matter how hard I pressed my 60 mL syringe, even when I dropped to a 20 mL syringe.Second Batch (40 mL Total Volume):
  • Testosterone Cypionate: 10 grams
  • Benzyl Benzoate (BB): 8 mL (20%)
  • Benzyl Alcohol (BA): 0.52 mL (1.3%)
  • Castor Oil: Remainder to reach 40 mL
Method: Used a caulking gun to assist with filtering, which was much easier. I used a brake bleeder to apply suction force in each vial, and it worked well. I was able to fill up my 4 vials with almost no loss.

Issues​

I'm new and made a lot of mistakes. I used up 5 filters as I didn't understand what I was doing, and lots of syringe needles to get this done. I had one vial with rubber stopper bits inside it, but I stopped using the large syringes for that despite it being faster. My theory is that the heat on the first batch likely darkened things. Any advice?I injected a little yesterday from the first vial I made and got no PIP, no issues. So far, I have 8 vials usable. Today, on my other 4, I used one injection yet again and got a bit of irritation, which went away. However, It still felt a bit stronger, so to speak, in terms of PIP.

Sorry I don't brew man, just an enthusiastic spectator. My only is comment is I'd definately filter that gear with corings, as there are going to be bits you can't see that can pass through smaller syringes, and your body's not a trash can.

Spaceman is one of the well versed brewers here and will be able to help you out for sure.
 
I use 10 ml syringes for filtering the last 20 + years. .22 filters. The larger the syringe the higher the pressure needed t filter. My oils are warmed but not hot at all. never had an issue with large needles, i use 18 gauge, and rubber stoppers. Think the have low quality or are abusing the stopper to much.
 
Were your filters hydrophilic or hydrophobic?

Buck makes a very good point about syringe size because larger syringes make it very difficult to push the plunger due to the higher pressure needed, just as Buck said. The 10 mL syringes are a good choice.

In regards to filters, use the hydrophilic filters for aqueous solutions and your hydrophilic filters for non-aqueous solutions.

Filter are heat sensitive, if you filter oil at 80c i can guarantee you that you broke your filter
Haha I bet I did and that's why the first batch is darker. It got less filtered and 2nd didn't break so it filtered more!

I got this vevor hotplate and it consistently overshoot it's temp and it's so annoying so I prob got it too hot
