Home brew calc and advice

[Skywalker33]

So I am fairly new to the boards and somewhat new to home brewing. I have been thinking about making the switch for financial reasons for a while now. I use a.a.s personally and am a small time trainer that implements small regiments to a hand full of clients. I am very familiar with finished oils/ compound selections ect and have a couple reputable sources. I tried home brewing test e from a Chinese raws supplier
Kung fu pharmaceutical I found on EC PLAZA. I have all the proper equipment and supplies, filters, vials, ba,bb, not. Syringes, beakers, auto clave ect. I just received a sample of 5g test e from DEE PHARMA and want to brew 200-300 mg per ml and my guess is it will be 2-3 vials off the top of my head. Does anyone have a link to a anabolic home brew calculator that does that small of a amount? Also the last time I brewed it came as a powder this time a chunk of off white product that was liquid at one time and had hardened. Please see attached images and see what you think and also if anyone has a decently priced 3rd party facility in could get testing done for purity ect. I use a Dave palumbo roids test kit but as we all know that is flawed and I would like a full spectrum analysis. Thanks again in advance guys!

I don't know of a calculator, but if you tell me what you want to formulate and the composition (as in, total volume and ratios of excipients), I can set up a google sheet for you. The math is all very easy.

The controlling equation is C = m / V, where C is concentration, m is mass, and V is volume. You have 5 grams, and you get to play with volume and concentration. That rearranges in two ways:

V = m / C
and
m = C*V

But your guess is essentially correct. At 200 mg/mL, that's 25 mL. At 300 mg/mL, it's 16.67 mL. That's 2.5 vials and 1.67 vials respectively. If you like clean numbers, you could prep it at 250 mg/mL and make two 10 mL vials.

That's ignoring excipients, but those are essentially handled like this:

C = m / (volume oil + volume exciptient)

If you have a recipe that tells you about excipients in ratios, often written in percentages or simply like 1:5, that's easy enough to calculate as well.

Heres one that takes into account the displacement of most common compounds. You can also save the website to your PC so you don't have to use the internet to access it.

Replace the (dot) with a .

EDIT: Also looks like basskiller is back online, so thats good.

If I ever go back to college I am hitting you up for math help

Oh man thats giving me PIP just looking at it lol worth brewing it up and trying it but dont be surprised if that shit burns like a mofo! Try ordering test C next round as it has a higher melting point and less likely to melt/re solidify in transit.

Thanks guys all the help is much appreciated

have you brewed this yet? personally it looks like bad raws? look like they got wet. my raws are like powder sugar. no clumping, my npp sticks A LITTLE. tren, test c are great.

bingbong is right. i wouldnt order test e to save my life for raws. melts way too low. some suppliers already ship it half way brewed because the product was getting destroyed during shipping.
