They're slightly shorter and thinner. They wont fit in any of the pens we have. The pens that use them are harder to find and disposable.

@SEOCoder spot on. I do 6mm for glp because i really want to get the "fat juice" in there but 4mm is plenty.

@diegoc What Diego said. Buy some v2s and and try it.

The pen needle might be too short to work with that pen. I don’t bother with the caps, personally.

I like keeping a bit of a diary here in case it is helpful. I find that when I am doing my prep, I often refer back to Randy’s videos to make sure I am doing things right. Today I was reconning 3 MOTS-C vials and loading into a pen, 2 vials of NAD+(500mg buffered), 3 vials of Tesa, and 4 vials of ARA-290 for the bride’s rat. As you can see, there is a lot of prep gear to be used for this since I am basically running 4 lines at once. Everything went smoothly, though I have to say that my fixation with process and cleanliness ran directly into my desire for economy. Once done, I loaded the carts into one of my Gansulins, a V2, and a new V1 I just got. Most of the stuff you see is either available through Peptide Critic or is the same stuff used in the videos. There is always a lesson. This week’s lesson, actually last week’s, is to recon NAD+ with 2.5ml instead of 3ml. If I use 3ml, then by the time I have dissolved both vials, the volume is more like 4ml and it won’t fit into a cartridge. There is a lot of stuff in a 500mg vial, and not just filler.

@MyB said in Peptides that work with nasal sprays: Technically anything with a Dalton weight under 500 will work. THIS! Yes it has to do with the Dalton molecular weight of the peptide for it to be absorbable via nasal route.

@Steve Im pretty much of a pen connoisseur as well. I have bought all of Randys pens and some others. So in my personal view i love my V1, why? Because it has a clicking action that i like. The V2-V3 practically, you push and its goes so you need to be more of an intermediate user if your trying to go slow. The new auto Gausen pen, is were i keep my Reta, its pretty bad ass, but i dont think i would swap pen vials or have 10 auto pens either. Randy just got a new Gausen pen not automatic im going to test out.

@mrjoshua44 It’s funny, I have cut my drinking by 90% or more since going on tirzepatide. My wife moved from Ozempic to Tirz and she hasn’t seen any reduction in desire for booze at all. The variability in these effects fascinates me. Think of the money we’re saving! Well, I am spending all that money on peptides and peptide accessories, so maybe not saving that much.

With regular pens, you have to press the plunger manually to dispense the product. Auto-injectors are spring-loaded, so you press and hold the button and the pen smoothly dispenses the product. I think they are both accurate. The problem that you describe is, imo, a separate problem. You are trying to dispense an amount that is barely greater than the margin for error. If you are injecting 3 units, and you lose .5-1 unit to inaccuracy in measurement or something else, and then you lose a little more due to dripping or failure to inject completely, you could lose a substantial amount of the product. If I inject 200mcg in 3 units and lose 1 unit, I am losing 66.6 mcg of the stuff. If I am injecting 200 mcg in 10 units and lose 1 unit, I am only losing 20 mcg. It might make sense to dilute you peptide to make it easier to get accurate and consistent measures.

@Randy Holding down the button worked perfect this morning, that was definitely my issue! I do put the pen in a baby wipe warmer on medium heat overnight which I think helps with the flow (29 gauge). But my primary reason for using the wipe warmer is it eliminated the subQ lumps I was getting when injecting cold.

I have a 1.5 year old v1 thats lived in the fridge its entire life. Still as accurate as day one.

@Bubba, the pens go down to 1 unit; not sure why you would want half a unit. Just double the back water when you reconstitute and use 1 unit. I think Jeff covered this on YouTube https://www.youtube.com/watch?v=geNpx5sJH3k. Basically, if you use as little as 1 unit, the little drip at the end of the needle contains more peptide than if you were using 5 units. I normally reconsitiute things so i'm doing 10units....Unless it's GHK-CU or something that stings, then maybe 20 units.

what was your order number. Chances are you got UV sterilized as we had a thousand of those come in at one point.

Thats a good question for @randy … I think he swaps them but when i was doing 4 peptides like bpc, TB, KPV, Ghk in all different pens i would use the same needle and toss it when done. Got the blend now so not needed. However i never mixed the needle with my RETA

I find it varies from batch to batch and vendor to vendor. My bride’s rat just started a new vial and found it burned. Mine started a vial from a different vendor and found it didn’t. I generally don’t have ISR’s anymore by injecting slowly. Was recommended by someone and oddly seems to work.

1 ml with 10mg (is it tested at 10mg or labeled 10mg, big difference) will give you 100 units = 10mg, so 10 units would be 1mg.
