Recently switched my tirz from 20mg/ml to 30mg/ml. S
To go ahead and take less juice.

I remember seeing someone that said Reta needs more bac water than that or it might not reconstitute properly, which sounds like horseshit to me.

But I just finished a bottle last week ready to make another and id like the higher concentration. Thats horse doodoo that I need more than 2ml to reconstitute, right?

Reta and Tirz have a max solubility around 80mg/ml.
My go-to concentrations are 25 mg/ml. This allows me to stay around 0.30 to 0.40 ml per injection. Since I put volumes of 0.8 ml or 1.2 ml into the vial, I prefer using 1 ml syringes to get a better reading than with 3 ml ones.
 
Why not decide based on your dose? Just pick a concentration which will result in a reasonable number of units (for your dose) - not too small or too large. I consider 20–30 units to be good. What do people aim for, generally?

Yes very good point, and this is the basis for reverse calculators.

And also the fact that the nominal mass of the vial shouldn't be relied on anyway, so nice round recon amounts like 2mL shouldn't be relied on. I just saw a Jano CoA from a month ago for Uther elora with mass 33% higher than nominal. Very good, but also very very bad.
 
There was a chart about 1.5 years ago that showed "ideal" amounts to mix with various peptides.

I think the question was framed around what works as well as what is the minimum amount needed to effectively "mix" the mass.

this is why this response resulted in thread closed.

This is generally not an issue until you get into large Mass like 60mg etc as most people are not going to mix such small amounts.

Sorry I do not have the chart, maybe someone else does.

Most of my GLPs mass results are in the +5-10% range...I kinda just figure the extra goes towards the filtering tax and dose based on nominal...But yeah, with a huge difference, I'd start mathing based on the mass result...

I can't remember where the information came from, whether it was an article or a patent. For bibliographic searches, I ask Gemini, it's faster than I am.

I plan to buy some 60 mg in my next order. That will be 6 doses, so 1.8 ml or 2.4 ml. I'll probably stick with 25 mg/ml.

Ya, at 8mg i slammed 27 units after I started this thread. I think people generally aim for as little as possible.

Just as an aside, already taking so much glp1 that unexpected mass and extra mg aren't going to affect me all.that much, in the last 23 pounds of my weight loss and shooting for the moon to get to goal.

Hopefully can taper down some when i get to where I wanna be. Till then its balls to the wall.

How did you end up with 27 u?
I'm just starting to get used to twelfths and haven't figured out how to handle sixteenths yet. Here, we're going from 3 cubed to 2 cubed. What quantities are you working with?
 
I’m kind of tired. I read through the thread. I know you wanted less fluid into the belly. But why skimp on 1ML of water? 3ML makes the math so easy too. I just started doing 2ml on 40MG of Reta. I was doing 4ML.

Yep, exactly. And edited to say, ty for checking my math! Wouldn't be the first time I've messed up a dose! 🤣
I have a spread sheet that has a block each for individual peps, with ml dilution amount per vial, mg of pep vial, and the mg/ml of the filtered vial...then line blocks of dose amounts in mcg or mg paired to a corresponding unit amount...Some doses haven't changed for weeks, but I still look at the chart before pin Every.Single.Time just to make sure...
 
The marhbis one of the fun parts

The math is one of the fun parts of all of this 🙂 but going forward at 8mg/27 units easy to remember and ill be there awhile anyway.

And you are right in a sense, what does it matter? But personally I want the smallest injections possible as I take quite a few of them these days.

Up until recently I was all about 20mg/ml just like your post, but after moving to 8mg on reta and tirz, home stretch of my weight loss, 30mg/ml is preferable.

Any way you could share the chart? That would be really great.

I don't 😂🤣😅

60mg/30ml=20mg/ml
8mg/20mg/ml=0.4mL

The math doesn’t seem easier or harder than using 2ml. .4ml is a round number but it won’t fit in my most common .3ml syringe.

2.25ml into a 60mg vial would make the 8mg dose an even .3ml.

I label the vials with the concentration, but I could put the typical dose info on the label as well.

Understood.

I'm much lazier: when I went to these levels, I took 4 x 7.5 mg from 30mg. I've also taken 3x6.7 mg from 20 mg of Reta.
I often use the same amount with all my pens, which helps me avoid making a mistake, and I put a pretty label on it with the dose, and I don't inject anything until after my second triple espresso of the morning.

How many Mg's are you taking to use 60 Mg's in a timely manner for 1 person?

I was only making the point that I wanted to use less too. I don’t know why when we start peps that we love the 1:1 ratio so much. I guess it’s like mentioned earlier. When you’re doing 1 pin a week who cares. When your doing 15 pins your like, holly shit I’m a walking bottle of BAC Water.

I usually use 1 mL. I like smaller shots.
Well, my dose at 9mg would be 30 units. I could switch to .5 syringes. I could do that.
Someone needs to start a R140 recon thread.

I use 1ml when possible, because i am cheap..
but.. I use 2ml on T60 because I find it more difficult to properly measure 15mg/.25ml

You're overcomplicating the calculation.

In a little over three months of working with gray peptides, this is the first time I've calculated a concentration, and only to contribute to this thread. It's not that I don't know how to do it; I learned it when I was 13, launching powder rockets from the backyard (and, additionally, during my three master's degrees in biochemistry and genetics).

We only need to know the concentration in a few situations: to measure the concentration of something else, or when preparing a stock solution intended for further dilution. There might be one or two others, but I don't remember (oh yes, measuring clearance or volume).

Your calculations are correct, but they require knowledge from middle school. I'm lazier, so I only use calculations from elementary school.

For example, I want 4 doses from my vial, so that’s a total volume of 4 times the volume I want to inject each time.
I got 0.6 ml with the Mounjaro KwikPen: never again! So I’m sticking to 10U to 40U per injection.
