Thread: Powder Weights

u dont need to know the weight to dose correctly

That's a good list bro

I always just set powder weight to
.9

u dont need to know powder weights, u guys are making things too complicated

thanks sloppyJ

If your a noob sure just go with
.9 easy to remember

But if u want to get as close as possible why not go exact..that isn't really hard to input 3 numbers

On my next brew im going to use .943, why the hell not.

I like this

I have to disagree with you. If you are in the market of selling"good enough" then you do not need to know the weights. Based on the numbers by sloppy there would be a decent size discrepancy between the standard .75 and actual weight, assuming actual weights listed are correct.

Test prop for example would yield a 1.55% difference for every 100 ml of prop made, meaning at the .75 weight would produce 98.45 mg/ml. Not a big deal but let's look at test E.

Test E would yield @ .75 weight 238.6 mg/ml. Not saying this is bad, but under dosed. Again, this is only assuming the numbers above are correct. The higher the weight, the more concentrated the dosing will be.

So to rebuttal your claim, yes it does matter but to what degree? If you are okay selling slightly under dosed gear (not implying you are, i enjoyed running your gear and felt great the whole time) then don't worry about the weights.

suprfast,no offense, but u dont know wat ur talking about

here is how u do it


first determine how many ml u will make,let's say 100 ml

u calculate grams of powder based on dosage. then u calculate ba and bb which is simple,as it's a pct of the 100 ml solution

now after its brewed and fully dissolved,how much oil do u put in???

simple, add enough oil to get to 100 ml

u dont need to calculate powder weight, the constants are powder,ba,bb. the oil will vary, but it's already done for u by the solution

I think you are confusing weight with volume.

If i submerge a one cubic foot chunk of lead into a gallon of water it will displace the water exactly the same way a one cubic foot box of pencils would. However the weights of both would be different.

Math is specific as is science. Guessing/guesstimating works too with a margin of error.

no,ur confusing it


the powder and solvents are dissolved fully before the oil is poured in


no one is talking about weight

since everything is already dissolved, powder displacement has already happened before oil is poured in


for a 100ml solution, if u use test enth and and prop, the total volume might be different after it is dissolved, but it's already dissolved and oil to be added will vary, but u just add oil until it hits 100 ml

lol... ?

Looks like both methods come to the same conclusion, 100ml of end product.

You don't have to dissolve everything before adding the oil.

Your method will would well if you want to eyeball 100ml on a beaker, which is easy. But when you are doing 1000ml at a time "eyeballing" the line on the beaker can have huge margins of error.

i do 1 liter,makes it even easier

if u have a professional lab beaker that is properly graduated, the line is very accurate,there's no huge margin of error at all

all you have to do is maintain an even eye level with the line

you also add more powder and go a little under the line to guarantee it is dosed correctly or slightly overdosed

and there's no reason not dissolve the powder in the solvents before adding the oil if you do it this way


1 liter batches make calculating obsolete btw

I've been meaning to ask, what carrier oil do you use. That was some smooth tren.

usually gso

going to try cottonseed

My scrip test cyp is cottonseed.

It's a little cheaper and the only argument against it is the cso doesn't have restrictions for pesticides regulated by fda. Not sure if usp oil makes a difference in purity vs food.

If you don't mind me asking at you running the standard 2/20 or 2/18 for ba/bb?

So from what I'm getting, you have a beaker, add BA, BB, Powder, then GSO till you get to desired quantity?

This method works also... For those that are not as 'literate' with math, this is a good way to do it.... You will be less likely to have any 'oops' this way...

Agree it works. Only difference is the unknown for how much oil is added.

Pars dumbed it down for us newbs. I like the mark approach. I'll post my really basic spreadsheet later. As weight goes up of the powder oil goes down, vice versa.

Margin of error(as a percent of the whole) is actually greater with smaller quantities...
If you are over by 10ml, on 100ml(10%error)... If you're over by 10 ml on 1000ml(1% error).....

Just pick one of the methods and use it.... Don't try combining several different methods... Pick one, stick to it.. and learn from any errors that may occur(many things are possible, start with a small batch and practice)

Or just practice with sugar and water... Til you kinda gave the processes down.. then you aren't wasting product...
Pm me if you can't figure something out and ill help guide you through it...

shit, now i am confused again

How about I fly your ass out here when I get ready to do something overburd?, LOL. I drink beer why you make my shit, lol
I promise, I will come to the stove from time to time, rub your shoulders and ask if you need anything to drink. I sware, lol

Super easy pork chop. I built a spreadsheet that basically will break it down by cost of vial(30ml), with all items needed. Nerding out.

USP grade cottonseed has to be free of chemicals/pesticides, etc... USP means US Pharmaceutical(grade)... it is a common carrier for US Pharmaceutical oil based products(as it is very thin, light, colorless oil).. and It's cheap!!!!
drug manufacturers use several different oils as carriers, but I do believe that cottonseed is one of the most common.

pretty much.....

It's not real difficult(though certain compounds can be trickier to get them to hold).... this is where experience(and a chem background really comes in handy)....
some compounds do not require you to dissolve the powder in solvents first(before adding oil), but I do it EVERY time... the is less room for error this way(and they usually will 'hold' better....many times you can tell just by how the powders dissolve, and to what extent they dissolve, in the solvents, if the gear is gonna hold after you add oil....
