    Unfortunately, this is not a Dr. Scholl's commercial.

    After the dose this morning I noticed something weird with my peptide that I never noticed before with any peptide. Is this the gelling I've heard people refer to? If not, what's going on? It is MOTS-C 40 mg reconstituted 16 days ago with 3mL Hospira BAC .9% sodium chloride. Hospira (not expired) has been opened for approximately 35 days, kept at room temp and wrapped in aluminum foil. Peptide has been kept refrigerated both before and after reconstitution.

    I only have one week left in my 4 week protocol (short I know, first timer). If I open another 40mg the majority will be wasted as it will be older than I'm comfortable using when the next protocol comes up. Should I just end the protocol early?


    Always great to try and identify what if anything has caused an issue but it is worth mentioning that shit just happens sometimes. I've had this happen to one vial. Recon a second bought at the same time as the first with the same hospira and it was fine.

    I know you all love your Hospira bac water. MedexSupply has it on sale.

    Save some for me!

    I have been on a NIIMBOT M2 high lately, spending a lot of time on the Nexaph and Peptide Niimbot TG and playing with a few basic templates.

    I wanted to create a master thread on this forum for people to share their M2 templates seeing as how not everyone is on TG.

    To open a template:

    1. Copy the odd text for the template in its entirety
    2. Open your NIIMBOT app
    3. A dialogue box will appear in the app asking if you would like to "Allow Paste" > Allow the paste
    4. The template should open and you edit it to your hearts desire

    Let me know if this is NOT the correct way to share templates as this is a work in progress for me too, especially since I am trying to do this on my PC rather than my phone.

    To share a template:

    1. Go to your Niimbot app
    2. From the main menu > Click on the 3 dots > share
    3. The app is quirky and only gives you 2 options: Message and WhatsApp
    4. Paste it into your messenger app (or anywhere, it doesn't matter)
    5. Cut it from the messenger app and paste into the forum or wherever else you want to put it (this is the part that's a bit of a struggle for me because I don't use the forum on mobile)
    6. Still need to confirm this actually works for everyone

    @MikeMiranda your link just brings me telegram website, but the SNP one worked.

    Pen owners, we want to hear from you! Which research pen do you reach for most?

    Vote below (one pick, and you can change your vote later), then drop a reply telling us why: dosing accuracy, build quality, cartridge fit, click feel, travel-friendliness, whatever matters to you. If you don't use a pen yet, vote No pen and let us know what's holding you back.

    Curious about any of these? You can compare the full lineup in the Pen Shop.


    @Stevepep So this? https://peptidecritic.com/store/peptide-critic-research-pen-blue-copy I believe it comes with built-in cartridge and has the same loading process as Jeff's video tutorial, right? @randy?

    "Thymalin is a polypeptide complex originally extracted from the thymus glands of calves and studied for its role in immune regulation and cellular aging."

    Anyone researched this peptide?


    @vpeps Yeah that figures. My issue with real Thymalin is that it’s 5ml in an ampule and you can’t really store it from what I’ve heard. I don’t know about you but jamming a 5ml shot into My ass is not My Idea of a good time. I have not quite figured how to administer it otherwise. Maybe filter and aliquot into another vial? At this point I’m almost considering just finding a china source that can get all the injectables and buying 10boxes each for resale to aficionados. Maybe in single vial form for the less popular ones like bronchogen

    Has anyone tried Reconstituting their research peptides with Hospira 0.9% Bacteriostatic Sodium Chloride (30 mL)

    Theoretically speaking it might help to lessen the sting from Peptides like Mots-C

    I heard RETA was a hard no

    Anyone else have any experience or knowledge in this area ?


    @MikeMiranda said: NAD+: Highly sensitive to the pH and ionic changes introduced by sodium chloride. Yeah! If it's UNBUFFERED! Too many sources and vendors don't give buffering info on their NAD+. Unless they specifically state it, I don't buy from them, regardless of price. Not your doing, @mikemiranda ; I'm with @commander and don't trust any of these lists. Have not had a failure yet using NaCl with SS31, MOTS-C & NAD+ buffered. I use regular BAC for Cagri, Survo & KPV, as none of them sting me, so, if it works, I don't fix it. I'm done with SS31 for now and taking the other 5 only.

    Does anyone know why H BAC has disappeared from PeptideTest site without a trace? Not out of stock but simply disappeared. They were my go-to site as I don't prefer buying bulk crates.

    Similarly Westend Medical Supply site has been blank for several weeks now.

    What's going on?


    @Nuncles Yeah they replied to my email saying some website issues and redirected me to Sterility. Any idea about why Westend and their sister sites are blank for several weeks now? Bacteriostaticwater and Westend and one more.

    Do pen needles larger than 29g exist? My google fu hasn't had much luck but would like to see a 27g or 25g pen needle for some research usage.


    25g x .5” would be ideal but 27g x .5” may work.

    Took the peptide. With in 2 hours I was vomiting. Went to the E.R. and was told that I had septic. Three days in the hospital. As you can imagine I am very angry about this.

    This is horrible. Sorry to hear you two had these issues likely a sterility issue. I had a similar issue when I was just getting started and didn’t have the peptide critic education I now have. Thanks for reporting on this garbage company

    Jeff- kindly relocate if not appropriate for a new category.

    Multi-vial care package delivered today from BioLongevity, pinned both with 30 minutes between each. No site reactions, feel fine, great actually.

    Super intrigued by both, I've done my homework. 60's male in great health, 2.5 year carnivore, focused on maximizing healthspan. Anyone else throwing caution to the wind and researching these two?

    Response from BLL - IMO very informative. As I said before, I love learning and never settle for answers that are "should be" "probably ok" and the likes. Here is the response: Thank you for the thoughtful question, and we’re glad to hear you’ve been pleased with the product. The two concepts are actually measuring different things. Stability in a vial refers to how well the reconstituted peptide maintains its chemical and physical integrity while being stored. Temperature, time, pH, light, oxidation, and other factors can contribute to degradation, which is why refrigeration is recommended after reconstitution. A half-life in the body, on the other hand, describes how quickly a compound is cleared or metabolized after it enters a biological system. The environment inside the body is very different from a vial sitting at room temperature. Protein binding, including albumin binding, can affect distribution and can protect a compound from rapid clearance or degradation, thereby extending its circulating half-life. So, a compound can require refrigerated storage after reconstitution while still having a comparatively long biological half-life at body temperature. The storage-stability timeframe and biological half-life are not directly interchangeable. Because our products are sold strictly for research use only, we aren't able to provide guidance regarding human administration or individual use. However, I hope this helps clarify the distinction between storage stability and biological half-life.

    Purchased 20mg Tesamorelin from verified peptides. Used 2mL Bac water to reconstitute. It was a bit cloudy but figured it would dissolve after some time. The plan was to use that evening. However when I retrieved the vial it had completely gelled. It’s unusable and I have 2 more vials I’m not that excited to reconstitute.They were pricy and I did send them an email with photos. Waiting to hear back from them.

    I had the same problem with a different vendor. I was told to use AOD water instead of Bac water. I have never had this problem before using Bac water. I now order from Noxa.is in Manila. They are first class, They test everything using Janosek. If in Philippines, They are the best ones I have found I Totally trust them.

    I have been taking tirz from a compounding pharmacy for the last year and just moved over to using the Neaxph version. I purchased the 10mg vials since I am micro-dosing but CoA indicates overfill (which I expected) of 11.85, 11.90, 11.95. Do I take the average of the 3 to calculate, or continue to l the vial size of 10mg, and proceed as normal.


    I usually take the average of all available test results, and round up or down to the nearest whole number. Because nobody can accurately draw up 20.5 units on a syringe

    Hi, I wanted to see everybody's opinions on some of the neuro blends out there. I am currently taking KLOW and CJC+IPA with great results, and want to add something for a cognitive boost. Specifically focus, memory, clarity, and calming. I have been researching Semax+Selank, and come across some other blends called NeuroMatrix, which is PE22-28 (10mg), Pinealon (10mg), NA Semax (20mg), NA Selank (8mg).

    Does anybody have any experience or thoughts on this?


    @dispensarysupport "dispensary"support? As of thc?
  • S

    We recently sent off two items for testing, SS-31 50mg and KLOW, to vanguard one came back under purity the other stating it was missing a compound, we thought this the perfect opportunity to compare Freedom diagnostics and Vanguard laboratory, I wanted to drop all 4 COAs here in this chat and get the peptide critic communities opinion

    As these results show that these two labs have within 3-5% standards of one another on mg amount, and on purity standards, what do you guys think?

    How to Make a Peptide Nasal Spray (Step-by-Step Guide + Do's & Don'ts)

    🎬 Watch on RandyTube: How to Make a Peptide Nasal Spray (Step-by-Step Guide + Do's & Don'ts)

    Learn how to safely prepare a peptide nasal spray at home with this comprehensive step-by-step guide. This tutorial covers proper mixing techniques, sterilization, storage, and important safety considerations.


    Comments posted here show up under the video on PeptideCritic.com, and vice versa. Questions about the technique, gear or the math are all welcome.


    @HockeyRat My method is to take everything apart and soak all the pieces - bottle, pump sprayer, pump sprayer tubing, and cap - in isopropyl alcohol for 10 minutes. Then I rinse all the pieces with distilled water and let them air dry. If it's a brand new sprayer bottle, I'll first wash everything with dish soap and water, then use the above method.

    Quick question for a few suggestions, please I just added GHK-cu to my Group buy purchase. It comes in 100 mg vials. Normally I use 50 mg reconstituted with 2 mL of BAC water. Recently I used my first bile of 80 mg reconstituted with 3 mL of BAC Water. It stings a little more. I use a pen instead of a disposable needle, so I can’t just add more BAC Water to it. How in the heck will I use 100 mg vials? Any suggestion?


    @wisgal64 I hate the sting and started at 15ml in a 20ml vial. Got it down to 10 and it was bareable for me. 10ml vials on sale at Farris that another poster turned me on to. https://www.farrislabs.com/products/vials-sterile-empty-20mm-10ml?variant=34773764407464
