    As some of you know I go off the deep end with labels. I may have bought a die-cut sticker printer just to make some funny stickers for giveaways and now I use them to label everything.

    Here's a few examples.

    24425.jpg

    Tonight I grabbed the niimbot and realized I had some white tape and clear labels. Surprisingly, I don't know why I haven't been doing this more often. Really looks nice against the V4 plastique and I tried it on a few other pens. It looks good, It's easy to read and I don't waste 30 minutes trying to get something that looks awesome that three people might see πŸ˜‚.

    I guess the point of this post is keep it simple.

    Oh and lets see your labels!

    @NobleONe From what I’ve read, you need to remove the RFID chip from a roll and use custom firmware. I need to double-check the steps, but apparently you place the chip near the bottom of the Niimbot, start printing, and then move it out of the way. My understanding is that if you turn the printer off or bring the chip back near it, it’ll count all the prints made while the chip was out of the way. I did see the black and red ribbon, but from the examples on the Niimbot website, I thought you could only print black on the left side and red on the right.

    Dihexa is an oral peptide used for mental acuity and clarity. It is focused on neuroregeration and neuroplasticity. It is 10,000,000x higher potency than BDNF, which may or may not mean anything to you.

    I am curious who has researched this, and what you have found. There is very little out there about it. Randy and I have talked about it a bit offline, but other than that, I have not seen much. I would like to see more. Also note that very few vendors are selling it. I am told this is in part because it is hard to make proper capsules.

    I have run two research runs this year. 1 was 12.5mg x 60 days, and the other was 7.5mg x 50 days. I cannot honestly say with certainty that is helped, though I do feel β€˜smarter’, it might be due to all the other changes, peptides, lifestyle improvements, and not drinking or using, ahem, recreational substances. (Weed, okay, no weed! Though I might get contact highs at the train station.)

    Post here if you have researched dihexa, what your results were, where you sourced it, etc.

    @CMEffie17 I have Semax, Selank, Adamax, Celebrolysin, NAD+, GHKcu, Retatrutide in 5-10ml nasal sprayers. Yes I am researching all intranasal, focusing on the brain. As for Adamax, I have 10mg in 8ml and it is nothing to sit around considering the half life. Perfect for an active life. Semax you have a little more control due to the shorter half life, it kick in right away. Selank for stress, anxiety, cognitive fatigue. Too much will put you sleep. You have to find their sweet spot. If you feel they are too much dilute and titrate up for better control. That goes with all nootropics and peptide that have a quick onset. Learn how to microdose and titrate up. I use to bite off pills till I felt it right. Be patient. I been researching oral phamalogical and natural nootropics for years. Peptides are at a whole different level. This round of peptide I will be ordering Dihexa, Pinealon to research and looking for a good deal on NA-Selank. I will also restock on the following: CDP- Choline Modafinil Bromantane 9-MeBc Alpha gpc Noopept Adamax Semax and Selank. *Hint hint... looking for deals

    Wow new research material.

    @randy Would it be available from any of the vetted vendors on the site?


    @davidbrown id say no but it seems to be crushs new go to, but with all then misspelled words and wrong info on crush vials (about a 6 weeks ago) they seem likena gray company operating in public now. Just my opinion

    One transfer needle per product, no cross contamination, no pushing unconditioned air into your vials, very little purging necessary once you load your pen. This is my method for loading pen cartridges. I think it's less wasteful and more sterile than the "second needle for venting/breather" method.

    My process:

    Disinfect all the vial tops, pen vial filling station block thingy and whatnot that are involved in my current project
    Use 3 ml transfer syringe to draw 3 ml of sterile air from empty pen vial (now it's under vacuum)
    Use 3 ml transfer syringe to push 3 ml of sterile air into bac water vial
    *DO NOT REMOVE NEEDLE
    Draw desired amount of bac water out and remove needle from vial
    Fill lyophilized product vial with bac water slowly down side of vial
    While product is resting and rehydrating, use same transfer syringe to draw another 1-2 ml of sterile air from pen vial (stop if the rubber bottom plug starts to get sucked up the vial)
    Once product is dissolved and gently swished for mixing, push the sterile air from your transfer syringe into product vial
    *DO NOT REMOVE NEEDLE
    Draw reconstituted product into transfer syringe
    *If there's still too much vacuum in vial to draw out all of the product, invert vial and syringe, then:
    Allow the air pocket in the syringe to be drawn back into the pep vial
    Draw remainder of product out
    Push the product into the pen vial gently down the side (be sure to have it on a flat surface in case it overpressures and tries to push the rubber bottom plug out of the pen vial)
    Pull needle out until it's at the very top of the interior of the pen vial
    *Start to draw air pocket out of pen vial with syringe
    Once you feel a lot of resistance as you are pulling the syringe plunger, transfer pen vial to the bottom plug pusher part of the filling station block tool thingy
    *Push the rubber bottom plug up as you are drawing the last of the air pocket form the top of the pen vial
    *Pull needle out of rubber stopper as soon as it looks like the air pocket is gone, but before product starts going up into transfer syringe
    *You're almost done, now purge your pen vial of air
    *Put your pen vial into your pen
    *Disinfect the top of the pen vial
    *Put a pen needle on it
    Cycle your pen plunger until it is touching the bottom rubber plug of the vial
    *With your pen tip pointed skyward, "inject" 3 units at a time into the air until it shoots a stream up
    *Now you really are done, try your concoction.


    @Stevepep Not sure why you're so hellbent on peeing in my Cheerios, but try to open your mind enough to actually read the procedure. Everything you have said to criticize it has been based on your misunderstanding, not the method itself. "If you are pushing the plunger up you are exposing the cartridge to contaminants and then adding your peptide this is not a good idea. You basically are taking a sanitized cartridge and making it unsanitary." Nope. I never said to push the plunger up until you are actually purging the cartridge. "I don’t follow if you are filling a cartridge without a vent you will blow the plunger out. If you are sucking the air out of the cartridge that will force the plunger up exposing the internals. It then would go down as you fill it. Unless I am missing something. Not sure if it was you but someone posted the use a device to free the plunger as well. Maybe you can get lucky and draw air out without the plunger moving and then add your peptide without blowing it out but you will get burned with this method if that’s what you are doing. Many of us have tried and you end up wasting a peptide on the floor" Obviously pure conjecture on your part because I do it several times a week this way and have never blown the plunger out of a cartridge. Basic understanding of how gases compress and liquids don't should keep you out of trouble here. The device I use to "free" the plunger is called a purging station. It's designed for (you guessed it) purging a cartridge. The center hole in it has a dowel with an OD slightly smaller than the ID of the cartridge. Nice tight fit perfect for (yep, gonna do it again here) pushing the plunger up to purge the cartridge. I don't know how it's possible to apply uneven pressure to a plunger when you are putting the cartridge down a hole that keeps it completely straight on to a dowel with a perfectly flat top. It's literally no different that what your pen does every time you push that button. Why do you need to "free" the plunger on a cartridge to get it out for sterilizing? I'm not sure how your pens work, but mine push the plunger all the way to the narrowed neck at the top of the cartridge. There's no way to use the dowel on a purging block to free it up at that point. It's bottomed out in the neck of the cartridge and the purging dowel certainly won't fit through the neck of the cartridge. "ummm your pushing the air out of the vial to let liquid fill the void. You're searching for a solution without a problem" Nobody thought leaded gas, thalidomide, DDT, Radium makeup, or poor hygiene during surgery were problems, either, until they knew better. Look at every video out there of somebody reconning a vial, including Randy's. The first thing everybody does is draws a syringe full of the same air that we all just breathed, burped, and farted out and pushes it into their vial of bac water. You gotta' make a deposit before you can make a withdrawal. The air we breathe is full of mold spores, bacteria, and all manner of things I just don't feel inclined to inject into my bloodstream in any quantities larger than necessary. I don't know about you, but I don't usually intentionally contaminate things. I apologize if my effort to make the process of reconning a vial and filling a pen cartridge more sanitary offends you.

    I've got (6) 20mg vials of tirzepatide unused and still in powder form that I purchased from CRUSH back in about May this year. One of my family lab rats decided she wanted to switch to Reta with two other lab rats. What should I do? Freeze it and hang on to it in case RUO Reta actually gets the axe or one of the 3 lab rats taking Reta has to stop for any future side effects, or should I try to barter a swap with someone for something else? πŸ€” I'm looking to increase my collection of KPV & SS31, and I've been wanting to start Epitalon.
    What is your advice and or do have a proposal?


    No trading. Unless you wanna see this place disappear... I see everything 🫣 Freezer it. Thats my vote. Some switch back to tirz when the rat plateaus on reta

    I've only just recently purchased from S1. I couldn't pass up Reta during their last buy two get one free on glps. I was able to get my reta for well under a dollar/mg. Best pricing I've seen yet.

    Not new to peps and syringes but just researching pens and wondered a couple things I haven't found answers to.

    First, I'm looking at getting the V2 from here as my first pen, for reta, thoughts on that or is there a pen better suited for a newbie?

    Second, with syringes, 8mm needle, I always pinch and go at a 45 degree angle but my understanding is you go straight at 90 degrees with a pen, why? Needle length is the same right?

    If needle length varies how do I know what length to get? Ultimately I would get pens for other peps I use like wolverine and kisspeptin (does needle length change based on pep?)

    Thanks for a great group!

    Has anyone used Prime Axis? Just wondering if they have a good rep. Thanks in advance.


    Lol these new unknown sites that keep getting posted here asking if anyone has used them before just becomes more comical by the day. No COAs listed, have to ask for it? LOL. Okay strike 1. Still naming it Reta? LOL strike 2. Does not put for RUO? LOL strike 3. Just too funny how bad and little to no effort is put in these pop up scam sites. Why anyone would even want to look at one of these places is beyond me, when you have reputable and vetted sites listed here. And if you want the cheapest that's actually tested and listed with real COAs, without dealing with TG gray market vendors, just go Nexaph and enjoy your real tested peptides at a low $ cost. Forgot the claim that they manufacture themselves. LOL. What a scam site. All the signs are there. Anyone who reads this in the future should just AVOID this site at all cost.

    The fear and scarcity tactics we have all fallen for let's discuss where we are.

    • Hospira is going away; prices are going up 30-40pct order now while supplies last. - Remember that one? Peptide test has had it at the same price for a year now after the email. Just saw it for $10 it sold out in hours. There are now group buys to get it. It's more available than ever.

    -KPV- getting banned in China. This caused a purchasing frenzy. It's still available

    -Reta- Lilly lawsuit, it's gonna be gone- Let the hoarding begin. Literally no impact other than some name changes

    • Drops, Sales, Pre Sales, who can keep up, get in on them now, prices are going up. It's a weekly occurrence, and the deals happen all the time. Miss this one, and in a matter of weeks there is another.

    -Customs crack down- it's been the same for over a year. Nothing has changed. They intercept 10- 20%. Factories are opening up in many countries now, which will loosen things up.

    We are easy marks; the more we fall for it, the more we will see these tactics play out. Take deep breaths and don't fall for every ploy. I need to keep telling myself that. My freezer is full because of it.


    @user_16538 I have become a hoarder like @randy and @commander I have years of stuff in my freezer. The only thing I don’t hoard is BAC since it expires
