    @Stevepep yeah. they dont care.

    Before anyone gets upset, yes I use Hospira. I am just curious if anyone has found a compatible maker that they use and trust. I am not looking for the cheapest finds, just other options in the supply chain. I wouldn’t trust those sold on Amazon but brands like Lamda have been tested successfully.

  • EXTROPIANE

    "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?


    @ogsteve you still can get something like this one (there is only 1 in stock now though and a huge shipping cost), it's lyophilized, or other variants when they are in stock. It says intermuscular, but if you split the dose into 2 or 3 you can do it subcutaneously too, in my opinion. But we know more or less what is there and may just compose a synthesized surrogate as well, which is more accessible. I would use a mix of Thymulin, Vilon, Crystagen - 0.5-1 mg each, and Thymogen 0.02-0.05 mg. Also supplement Zinc. See here. Or you can use pills of Vladonix or Thymusol, better sublingually, on empty stomach. But, so far, I didn't see any distinctive results in blood markers on any of these compounds, except a transient increase of neutrophils.

    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.

    @Stevepep yes, I wrote about it multiple times here. I had a misfortune to deal with this company first. They had Janoshik COAs, verifiable, they had extensive articles about how important to pick the quality peptides, how to choose them, all good information... And I was pleasantly surprised when I got Epitalon from another company and 1 mg dose didn't make me want to die immediately to end my suffering.

    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

    What has changed for you since starting Reta or Tirz?

    Not just weight loss either — what other benefits have you actually noticed?

    For me with Reta:
    • Snoring WAY less
    • Sleeping better
    • Weight loss, obviously
    • Noticeably less joint pain

    The joint pain one has me curious. Obviously carrying less weight can make a huge difference, but I wonder how much is from the weight loss vs. Reta itself.

    I can’t see into the future, but with some of the additional benefits we’ve seen associated with Tirz, I’m interested to see what the long-term research on Reta ends up showing.

    What changes have you noticed — expected or completely unexpected?

    Used Ascension Peptides to get some retatrutide and trizepatide. Ordered on a Saturday and came on Thursday. Order, payment was easy. Products works fine. I would order again if the price was right. Overfill on vial, COA has purity and quantity.

    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.

    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?

    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.

    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?
