Just checking I got this right?

[techiemichael]

So I’m just making sure I’ve got this straight, because messing it up is honestly terrifying to me.

Say I get a 5MG vial of Reta — that needs to be mixed with 2ML of Bac water, right?

My plan is to pull the water out of the BC vial, then put it into the Reta vial, aiming the stream at the inside walls and swirling it around until everything is completely dissolved.

After that, for dosing, every 0.1ml equals 10

Units. So for 1mg, I’d draw 40

Units — and that’s the starting dose I’m aiming for?

Thanks in advance for any help.

Those numbers check out as far as I can tell.

With a 5mg vial, I'd add no more than 1 ml of BAC. Try a tool such as this: https://peptidescalculator.com/

If you want 1mg out of a 5mg vial, you’d draw 1/5th of whatever volume you used to reconstitute it.

100 units = 1mL

40 units, or .4mL, equals 1/5 of 2mL.

Let the reverse calculator handle it (the link is in the signature), and draw to a numbered mark on the syringe ... plus make sure the vial's tested mass is known, rather than only the stated 5mg.

Skip arithmetic ... it doesn't do anyone any favors.

A 5 mg vial contains 5 doses of 1 mg each. My approach would be to add 50 units of BAC water, so that 10 units equals a 1 mg dose. Alternatively, you could add 100 units of BAC water, in which case each 1 mg dose would be 20 units. I prefer using smaller volumes and doing less math. That said, your original calculation was right. Calculators can come in handy too.

Nice work checking first. Being certain is the smart move. Assuming your vial actually holds 5mg, the math checks out. It's pretty common for the real amount to run +5%, which here works out to a 10% bump. That's a win for your budget, though it might not be ideal in other respects. The best thing to do is look at the C.O.A. for the batch you got from your supplier. Calculators for reconstitution and dosing are helpful tools....If it were me, I'd go with 1ml BAC and a 20unit dose, but that's only my preference...Your call.

That's a really good observation. Extra volume only works in your favor when you're aware it's there. This matters most when you're just starting out with injections.

Why did you go with 1ml of BAC?

A smaller amount to inject.

I lean toward bigger volumes for a couple of reasons.

1. When the solution is more diluted, there's a lower chance of an injection site reaction (ISR). With GLP's this tends not to be a problem, but it can show up often with "spicy" peps such as GHK-Cu, NAD+, MOTS-C, glutathione, and so on.

2. Measuring is simpler with a larger volume, and it gives you more leeway when it comes to +/-% of accuracy. I've come across recon and dosing suggestions that wind up calling for single digit units. Try drawing exactly 8 units in a 1 ml insulin syringe — good luck! For anything under 30 units, I'd much rather use a 0.5 ml syringe.

Yeah, less liquid. Personally, I aim for shots of 25 IU or under, and I'll typically mix the peptide to hit that volume or lower—though that's just my preference. For a GLP, taking a bigger shot doesn't really offer any advantage. My vial is 50 mg, and my dose is 10 mg, so I add 1 ml BAC to get a 20 iU injection.

Wait, what? 5% turning into 10%? That doesn't add up.

Where's the piece I'm not seeing?

That was a solid breakdown. Normally I lean toward keeping things minimal, but here it turns out the bigger amount is what works. Appreciate it.

Two solid points there. Thanks

Personally, 1cc/1ml/100units makes the calculations simpler, and because I have only a little experience, I lean toward injecting smaller volumes.

A 5ml vial might actually hold 5.5mg (while assumed to be 5mg). Since 5.5 exceeds 5 by 10%, that difference could be A LOT. Please, everybody, verify my calculations at all times and call me out if I messed up

Over in your opening post you called 5% unremarkable, and here that works out at 10%.

A percent is a percent. Perhaps .5mg of overfill is what you had in mind, which would be 10% here?

Overfills don't bother me, and neither does beginning at 40% of the dosing schedules that were trialed and are commonly used.

 

[techiemichael]

but if I begin at a low dose of 1mg per week, is it really a big deal if there's a bit of overfill, considering that most people kick off Reta at 2.5mg?

How you react plays a big role, and it's different for everyone. In the trials, the starting dose was 2mg. My own path was 1 mg taken twice weekly, then 2mg once weekly, followed by 4 mg, 6 mg, 8 mg, and currently 10 mg, with 4 weeks at each step. There are those who remain on 2 mg or 1 mg since the side effects are too much for them. If you respond well, it shouldn't be an issue.

 

[techiemichael]

That's helpful. I appreciate everyone's assistance. It put my mind at ease.
