First time attempting a Homebrew

[grimlock2009]

Hi all,

I'm going to do my first homebrew soon and hope I could get some tips and tricks which some of you acquired over the years.

The plan is to create the following:

10 vails of 250@10ml of Sustanon 2% BA 20% BB
10 vails of 100@10ml of Methenolone Enanthate (Primobolan Depot) 2% BA 20% BB

The oil is pharma-grade MCT oil as this was easier to source due to my work in the pharma sector.
I've added a picture of all the concentrations of MLS and grams with oils see attached.

Materials

10 gr Methenolone Enanthate
25 gr Sustanon
1L Pharma Grade MCT oil
40 sterile vials with tops
Benzyl Benzoate (150mL)
Benzyl Alcohol (30mL)

Vevor 85-2 Hot Plate Magnetic Stirrer (MAX TEMP 100C) with an RPM of 200.
500ml Sterile Glass beaker
20K USD calibrated balance -> Thank work for that
60ml Syringe
caulk gun



The only question I still cannot find an answer to is regarding which membrane to use for the filter I see people sell nylon. PVDF etc. but no clear reasoning behind why this material. could someone further explain this? Also if I am missing something please do let me know


I'll be sending a sample to @janoshik for testing to verify the purity and of course post the results here.

Is there anything i've missed in the steps ? just wanted to ensure i have it all written out before starting

Mixing
1. Heat the hot plate to 55C and turn on the magnetic stirrer.
2. Add the required amount of BB
3. Add the Raws
4. Add the required amount of BA
5 Add the amount MCT oil (GSO/CSO ect)
6. Let this stir for 30 minutes (until its fully dissolved)

Filtering -> still unclear to me
1. Draw up the solution with a syringe 50/60ml bd for example using a green G23 needle.
2. Remove the needle used to aspirate
3. Fit the 0.22 PTFE or nylon filter on the syringe holding the mixture
4. Fit a 23G green needle on the other end of the filter
5. Wipe the top of where you are injecting with an alcohol swap
6. push the liquid through with a caulk gun to the desired amount.
7. 1st bottle done
8. Wipe the top of the next and inject to the desired amount (repeat as often as needed)
- When the filtration becomes super slow it might be time to replace the filter

Between step 5 and 6 of filtering you should add a 23g needle for pressure relief to the vial.

Thanks, whilst looking for something else I found these at the office. Guess I wont have to purchase them anymore

Those are not sterile. You either need to sterilize them via gamma radiation or purchase sterile individual wrapped ones preferably 33mm diameter for easier filtration.

True, I’ve only got sterile pes and ca unfortunately.

So the correct thing would be to go for something like

PVDF Syringe Filter 0.2μm Sterile Hydrophilic Filtration Lab Filters, 33mm Membrane Diameter 10pcs, Individually Packed by COBETTER​

 

[grimlock2009]

Hydrophobic I mean.! We don’t want hydrophilic

 

[grimlock2009]

I think my source scammed me
For the raws.. could anyone redirect me to a reliable one ? I see allot of negative reviews about aasraws aswell.

It looks like you’re in good shape and did some homework…and it is rather easy obviously filtering into sterile vials and cleaning rubber stoppers are most important. The only thing I would suggest is doing something like 10 bottles of test prop to try out first time you brew and make sure you have a graduated cylinder …test p is cheap and easy to work with if you get up to it’s melting point and will hold in 1% ba and 18%bb

Thanks for the info, Yea im doing 13 bottles of Sust. Only attempted TEST P once and did not enjoy it. Made me feel on edge and easily triggered.

I've already cleaned the vails with a 5% bleach solution and plan on putting them in the oven at 170C for 30 mins before i actually add the Test (obviously waiting for them to cool down upside down so no dust enters)

Ast for the rubber stoppers i was planning on using IPA as a read that chlorine can damage the rubber. Any experience with that?

Yo be honest I don’t have any input on that I’ve cleaned the vials similarly to you and just put alcohol dabbed on the rubber stopper immediately after I filtered into the clean vial and I do like .1-.2ml sub Q to try it out before I go into a muscle…I’ve never had a problem the only thing was getting a graduated cylinder and my milliliters were right on point since

Ah yea I have one of those at work ill barrow

You really don't need 20% BB for anything (normal) in my experience. Any reason you're doing primo at 100/ml instead of 200?

To my knowledge 200 primo should cause more pip ? Also bayer only sells at 100

 

[813482584]

Yeah Bayer sells 100mg/ml because of therapeutic dosing guidelines, are you only taking 100mg/wk? 200mg/ml at like 15bb/1.5ba in MCT shouldn't cause pip as long as MCT doesn't bother you, though everyone is different. I prefer to have higher mg/ml so I can get say 600mg/wk of primo in 3ml instead of 6. It does come down to personal preference, but do remember, you can always cut the dose concentration down, but not vise versa.

 

[Denicnut2427]

I would stay away from making concentrations that aren’t the norm especially to start…also I meant to add earlier that I tried using 60ml and 100ml syringes to filter and it get very hard to push through and have had explosions. It’s much easier and not too much of a pain in the ass if your only making 10-20 bottles at once to keep drawing up in a 10ml syringe and putting filter on and filtering into your sterile vials…it only takes me about an hour to do 10 bottles ( I try to leave each batch I make at its melting point for about 25-30mins then let cool and filter) I hope this helps

Thanks for the 10ml syringe tip

I read that regarding melting temperatures yea but for sustanon there are 4 different temps so how would I go about finding the right temperature.

I could only imagine if I’d have to mix the sust myself and than start at the higher temp to dissolve working my way down

I would just leave it around the highest melt point it will be fine…which in this case I believe would be your test prop which is in the sust but you’d have to check all the esters
