Today was the day. I dropped the kids off at school, and opened up my kitchen for some home-cookin’.
Everything was in place as far as equipment, or so I thought. The glass beaker I bought was pretty thin, and I didn’t want to take any chances putting it in the oven. The other day, when putting away dishes, I saw that our one-cup measuring glass had “warranteed ovenproof” stamped on it, so that was the no-brainer. That solved that problem. So what I had was:
Benzyl Alcohol
Benzyl Benzoate
Cottonseed Oil
Ethyl Oleate
Test-Enanthate Powder
21g needles
18g needles
60ml luer lock syringe
3ml luer lock syringe/23g needles (left over from cycle)
20ml sterilized vials
caulking gun
22 micron Whatman filters
What I needed: 10 and 20ml syringes
Using the powder calculator (supermuscle.org), I knew I’d need 10g powder, .8ml BA, 8ml BB, and 11.85ml each of cottonseed oil and EO. That would net me a total of 40ml test-e @ 250mg/ml, with 2% BA, 20% BB. I went with that as a “tried and true” ratio as described in supermuscle.
I sterilized some spoons (for stirring) and the measuring cup by boiling them in a covered pot for 15 minutes. Once they cooled to touch, I dried the cup upside down in the oven at 250 degrees.
My first problem was using a digital scale. I put the cup on it, and tared it to zero. Well, the the scale shut off after I put about seven grams of powder in the cup. I ended up having to measure out little by little, then measured the original powder baggy to get to ten grams. I think I went one or two tenths over, no biggie. The powder started melting as soon as it went into the warm cup.
I added the .8ml of BA and the 8ml of BB, and put it in the 250 degree oven. It melted a lot quicker than I anticipated - within several minutes. I took it out, swirled it around, and let it heat for another ten minutes.
I added the 11.85mls each of cottonseed oil and EO, which is where the 10 and 20 ml syringes would have been handy. I ended up using my 3ml syringes for that, though, which was a little time consuming.
Back into the oven for about 25 minutes. I took the mixture out every so often and stirred it. The advice is to bake until the “swirlies” are gone, which I did.
I let it cool for about 15 minutes, then loaded up the 60ml syringe with the mixture, put on the Whatman filter, and attached an 18g needle to the filter. I put a 21g needle into the vial to allow for venting air, put the 60ml syringe into the caulking gun, and began filtering. I applied enough pressure so the oil dripped semi-rapidly out of the syringe, into the vial.
The first 20ml went fine. I started the second vial and noticed the oil was leaking from in between the filter and syringe. I figured either the filter was clogged, or maybe misthreaded on the luer lock, so I changed it out for another filter and needle. I noticed a small piece of the rubber stopper inside the vial from having to use such a large gauge needle, so next time I may use something smaller.
And that was that! All told, it was a simple process.
A public thanks to Tim and LillGuy.
I’m not due to start a cycle yet, so I won’t know until next month if everything went right.

Awesome description, and congratulations, 5.0! This is one of the best walkthroughs I have seen so far, really easy to grasp.
Couple questions. Out of all of the lab supplies you purchased, are there many that you will have to purchase every time you brew? Or is most of it pretty much a one-time shot?
Are you saving enough money to make it worth your while, or will you have to brew multiple or fairly large batches to make it cost effective? Or is cost not the issue and it’s more one of safety/anonymity?
Thanks for a terrific thread. I’ll be consulting this in the future.
