Did you verify how accurate they are?

I only ran 3 tests using water, at 10/20/30u. Results looked fine. Compared with other options available, having a medical device listing is a plus. At minimum it eased my mom's mind

Thanks, I'll take a look at those.

I own 2 V2 pens, 2 HumaPen Savvios, a gansulin, plus a few disposable ones.

Buying those disposables is something I really wish I hadn't done. My reason for getting them was doubt about whether pens would suit me or whether I could rely on the dose being right. Once the pens arrived, I checked every one of them for accuracy, and the precision of pen dosing honestly surprised me. These aren't exactly high-tech devices. I'm tempted to open one up just to see what's inside. For testing, I followed the instructions from Undergroud Supply and used tap water.

Over on Peppys, a person disassembled a few of them for a comparison — might be worth a look. If I remember right, the ones involved were the Convipen and the Gensu2.

A ConviPen and a Gansulin were taken apart. The internals turned out to be completely identical!

Hello,

In a few months I’ll be taking a trip and will be away for roughly 5 days. I thought about simply not doing the research during that time, but the stretch feels too long. Up to now I’ve only used standard syringes, but I noticed a mention of peptidecritic.com and saw that they sell disposable pens v1.2 and v2 at a fair price. Before committing to reusable pens, I want to test out the disposable option.

1. When flying, is it less risky to carry research materials in a pen rather than vials that might have labels and syringes, or should I avoid bringing them on the plane altogether?
   
2. Are the needle tips universal, so that if I purchase a bigger pack of tips now, those same tips will work with a reusable pen down the line?
   
3. Does anyone here have firsthand experience with the disposable ones from peptide critic that I mentioned above?

Thank you!

1. You can produce a label so it appears you're carrying Insulin while traveling. After countless hours going through Peppy's, this forum, and different telegram chats, I haven't come across anyone reporting problems traveling with peps in a pen.

2. Correct. Underground Supply offers needle sampling packets that I'd suggest looking into. I expected to prefer EasyTouch or BD Fine needles, but EasyDrips is what I settled on.

3. I haven't tried those, though autoinjector pens work really well for me. Both ConviPen and GensuPen2's have been used by me and each was accurate. ConviPens feel solid and have excellent build quality.

Just to make sure I've got this right — those 2 V2 pens you checked were also essentially spot-on when it came to dosing accuracy? That's quite something, given how budget-friendly they tend to be (at least next to the Convis, Gansu, and Savvios options).

Yep, I ran both V2s through testing and they performed flawlessly in my case. The precision of the dosing caught me off guard. Because I was using tap water, an already-used cart, and an insulin syringe, I repeated the process many times — purely out of curiosity. This wasn't a single trial. Being fairly OCD, I spread these tests across several days. Somewhere I came across the idea that the mechanism gets smoother the more it's used.

I got the 2 Savvios from Canada, and they cost just $30 apiece before shipping. I checked the Gansulin by testing it, but I haven't injected with it so far.

Thanks, that's helpful. One of these days I might go ahead and spend the extra on a Savvio, though I'm constantly juggling which seller carries the accessories I'm after so I can put together an order that qualifies for free shipping (at the moment I'm trying to track down carts, since Injection Shop doesn't carry them and I'm placing an order with them for other items today). So if I can grab sterile carts and the pen together, that's a plus!

I just blew a lot of money at Goodies Supplies. They carry a solid variety of pens, carts, and needles. I wound up getting a Savvio even though I had 0 use for it. My cart total was already so high that I figured why not

This is interesting. The items I'm looking for are available there, and the pricing is surprisingly low. Since I'm not familiar with toadspens, should I take it for granted that these smaller DIY vendors offer reliable goods, or could they simply be sourcing from AliExpress and marking up the cost? I'm quite drawn to picking up that Nest pen along with several carts—yet the cart prices are low enough to make me suspicious!

On aliexpress, you can get the carts for 50% of that price. With free shipping, $42/100.

Pretty sure they're simply reselling Chinese product, or in daro's situation I believe he sources from down south.

I'm fairly confident I located Toad's through quallіgator.

I'm a beginner when it comes to pens; I've just used up my initial cjc/ipa cart with the nest and am roughly 1/2 done with a Ghk/KPV cart using a convipen.

Convipen plus a few carts from Daropens and the Nest, along with additional carts and a pen needle case from Toads.

I'd absolutely suggest looking into several options before deciding. From what I've seen, reusable devices cost about the same and are a better choice than disposables.

Q1, in my view, would be simpler for travel, x pens, 5 * x pens in needles that are smaller than dice each. It seems like your Q2 has already been addressed. For Q3, I have peptidecritic’s v3.5. The quality is acceptable, though nowhere near the Savvio I picked up for roughly the same price. A name brand (Savvio) or auto-injector would be my strong recommendation.

I went ahead and bought several Savvio pens! After seeing folks mention using spacers with pens, I grabbed a 5 pack too (cost about $2). Do Savvio pens actually require those, or do they work well enough to use up all the liquid in the cartridge?

Every cartridge will leave some liquid behind when using a pen—that's just how it goes.

A few individuals use an insulin syringe to extract those final 2 units. I've tried that approach myself, though I question whether the effort is justified.

Still, won't the spacer pull out nearly all of it, and they shouldn't throw off the pen's accuracy?

Right. I've never personally dealt with needing spacers on Savvios, but there's no downside, and the accuracy stays unaffected.

Great, thanks a lot!

I have experience bringing both along on trips. During a 2-week stretch abroad, TSA showed zero interest in peptides.

My setup was an insulin case paired with ice packs that meet TSA rules. Zero issues. Ultimately it boils down to personal preference.

Pens win on ease of use — I ran the V2 without any trouble. They really shine while traveling. Go ahead and make the move.

And whenever I need guidance, professor YouTube is available to assist too!

Yeah, the pens are coming with me for sure. I ended up ordering a few Savvio pens, which showed up yesterday. I still have syringes to use up before making the change.

The final drops that won’t come out happen because the cartridge’s top end has a rounded shape. From what I understand, spacers are only required for Novo pens, since that brand is designed around specific Novo Nordisk insulin cartridges.

If I’ve got this wrong, please someone reply so I can know!

Right. On my V2 pens, spacers wouldn’t do anything… because of the shape, there’s roughly 10 units of dead space. What I do is take an insulin syringe and draw the remaining drops out.

And for the original poster… twice I’ve traveled outside the country, carrying 4-6 pens each trip in a TSA approved cooling case with ice packs. Neither TSA nor the countries I visited even requested to look at them.

Just received a gansulin pen through good life. This is my first go with a pen. Got it loaded, dialed in the correct dose, put the needle in and held for a count of 10, yet a few drops still appear once I pull it out. Is there something I'm doing incorrectly?

That happened to me as well, back when I removed the needle prior to the pressure balancing out.

These days I do it differently: I squeeze the skin first so I know I'm not going into muscle, then put the needle in and push down. Once I feel the injection has finished, I count to 10 while letting go of the squeezed skin, and only then pull out. In other words, I let the pressure off the injection site before the needle comes out.

With this approach, usually there's just a minuscule droplet left on the needle afterward.

I’m curious how they work out for you—I’ve never tried a pen myself, though I picked up a savvio just last week. Was there anything that caught you off guard or that you weren’t happy with?
