    Has anyone researched retatrutide alongside survodutide? Would this be a good combination for weight loss and liver fat reduction?


    atlas01 Actually I had just ordered cjc/ipa from peptidemaxxing...so adding survodutide to my protocol might be overkill I guess.

    As the title says, my house (built in 1840) naturally stays cold in the mornings before the sun hits it. So when it comes to reconstituting AOD, it can present a challenge. When folks say that both the BAC water and compound should be room temp, well that means 55°-60° for me right now before I get the fireplace going. Trying to mix those two at that temp is hit or miss on whether or not it’s going to cooperate. So I take both the bottle of BAC water and the vial and hold each one in my hands to slightly warm them, makes reconstitution a breeze. Just finished with this 5mg vial from Orbitrex, used 3mL of BAC water.

    Alright give me your secret or not having any micro bubbles in your 3ml carts. No matter what I do I always end up with some bubbles.

    Has anyone ever tried Vesugen? Where have you gotten it? What was your protocol? This is an interesting bio regulator peptide.


    I was gonna do a run of Vesugen an Cartlax forlike a month before ruinning BPC/TB again

    I was curuious if anyone has experinace with "frozen shoulder"

    https://www.mayoclinic.org/diseases-conditions/frozen-shoulder/symptoms-causes/syc-20372684

    Would any of the peps be useful in this case? BPC, Cartalax, TB400?

    Any live with this and have advice?

    Thanks!


    As an alternate you can start with some proven non surgical options such as Platelet Rich Plasma (or PRP) for adhesive capsulitis. PRP has a decent history of trials and research behind it. That would be my first option and then add the peptides in if needed. Love BPC for sure but wouldn't want to try it and results fall short of expectations. Personally had posterior labral tear's in both shoulders due to heavy lifting- now I still lift heavy with no measurable difference (had done PRP).

    @cathypowell have you tried the no sting water, I've only found it at 1 supplier and that's at medicalbacwater.com and it's the buffered bac water I use and have no issues at all with the sting or burn and found that using the butt cheeks works best.

    I purchased 2 of these pens from here. Has anyone done the own test on this? I went to 22 units and pushed it into a syringe. I did it a few times. I did not get 22 units. I compared it to the Amazon v2. Amazon one was closer. I love the stop technology though!


    @seadracos agree good post

    I’m researching a possible switch and wanted to hear from anyone who has actually done this sequence: starting on tirzepatide, moving to retatrutide, then returning to tirzepatide. I haven’t tried it myself, so I’m hoping to learn from people who have. How did your A1C and weight change after each move, and did tirzepatide work as well the second time around? I’m also curious about side effects, bloodwork like lipids and liver enzymes, energy and sleep, and whether you had to restart at a lower dose when you went back. If you can share your doses, how long you stayed on each, and whether you had labs before and after, that would help a lot. Thanks for any experiences you can share!

    Im relatively new to peptides have been on Reta for a month now, and started DSIP yesterday. I’m interested in SS-31 but I’m it sure of dosing and overall protocol, basically what a cycle would look like. I’ve definitely watched videos that give suggestions but I also feel that this forum has great info so I wanted to ask what your expende has been and how you folks have decided to run it. Any insight is appreciated.


    Actually I would maybe do more research before spending $$ on SS-31. SS-31 works by binding to cardiolipin, a molecule that is broken in genetic disorders like Barth Syndrome but present in normal people. Because you have existing cardiolipin that is not broken/missing the peptide has nothing to "fix". The human MMPOWER 3 trials that showed even at a large dose of 40 milligrams a day SS-31 failed to beat a saline placebo for physical fatigue or endurance. https://pubmed.ncbi.nlm.nih.gov/37268435/ There have been over 25 human clinical trials in total conducted on SS-31. All but one for Barth's syndrome failed to meet the goals vs placebo. The good news that it's very safe to take I also would really question the dosing protocols some clinics have- ask them where that information specifically came from.

    Genuine curiosity question, no agenda, no accusation. I can't figure this out and I'd like to know what people here actually know.

    Nearly every vendor sells bac water in 10 mL, some in 3 mL and 5 mL. But the Hospira product everyone references is a 30 mL multiple dose vial, and it's plastic, not glass. Most vendor photos show glass with a rubber stopper and a crimped seal. Not the same object.

    So where does the 10 mL come from? Possibilities I can think of:

    • Someone buying 30 mL vials and drawing them down into aliquots, which is a sterile compounding operation.
    • A registered repackager. The FDA NDC directory lists several labelers for bacteriostatic water that are distributors and repackagers, not original fillers.
    • A compounding pharmacy or outsourcing facility filling to order.
    • The vendor mixing and filling it themselves. Empty sterile 10 mL vials are sold off the shelf.

    What I'm wondering:

    • Has anyone found a manufacturer name, NDC, or lot number on a 10 mL vial, or is it always just vendor branding?
    • Has any vendor told you who fills it when you asked?

    Not trying to start a vendor pile-on. "Sterile" and "0.9% benzyl alcohol" on a label says nothing about who made it or how. If you know because you work in this space, I'd like to hear it.


    https://bacwaterco.com/ and that gig in florida sells under different brands, prob buys from the wholesaler.

    Pens vs Syringes: Which Wastes Less Peptide? Dead Space Compared (Video)

    🎬 Watch on RandyTube: Pens vs Syringes: Which Wastes Less Peptide? Dead Space Compared (Video)

    Pens or syringes: which one wastes less of your peptide? This short video compares the dead space in both. A syringe can retain 1–2 IU after the plunger bottoms out, while a pen tip holds under 0.5 IU. Small losses add up with frequent use.

    @justinlaughlin Justin, switching labs doesn’t answer what we asked three weeks ago. You said you only published results that matched your supplier’s COAs. Did any disagree? What happened to those reports and batches? Is that still your policy? And where are the batch-specific endotoxin and sterility reports? Its 2026. Why would anyone buy from you when we know of dozens of vendors that do more testing than you? Your published testing covers identity, mass and purity. Repeating “99.5% purity” (freedoms specialty) doesn’t answer either of those questions. As for Max, I accepted when he offered blind testing. He then insisted I tell him what I was sending, so I didn’t bother. And yes, I find your animated background hard to look at. You’re allowed to choose that design, and I’m allowed to dislike it. And you are listed. Just not how you would like. The warning is accurate and based on your own statements; calling it “damaging” doesn’t make it false. You’ve written plenty about my tone. The questions about your testing are still sitting there. I did update the warning but I can't erase the past.

    There is a news story making the rounds that actor, Richard Hanson had a Anaphylactic response to injecting CJC + IPA and subsequently passed away.

    https://www.usatoday.com/story/entertainment/movies/2026/10/30/richard-norton-cause-of-death-peptide-injection/92519001007/

    There are no details yet that I can find indicating where the Peptides came from. They appear to have 'prescribed' by a Health Practitioner etc...

    There is some indication that Richard was doubling his dose, which might have also been the problem. Some simple Ai searching did reveal that a CJC+IPA Dose could cause an Anaphylactic response.

    This is not the first time I have heard about Anaphylactic reactions to a peptide injection. I have seen more than one post from a user claiming to have experienced anaphylactic shock from a peptide injection. One of them from You Tuber Vigorous Steve who had a reaction to a mega dose of Mots-C and had to be rushed to emergency. The other story was from an Instagram guy who just happened to have an epi pen handy but was also hospitalized.

    For those of us with only the best interest of our research lab rats in mind, has anyone considered keeping an Epi-Pen handy..,, in a case where your test rat has a Anaphylactic reaction to a research dose of a peptide.

    I know we have a couple around the house for my wifes allergies. I think I am going to become a little more acquainted on how to use it.

    Just thought I would add a message from Vigorous Steve on the subject:

    Steve's Warnings to the Community

    Following the incident, Steve strongly urged caution with research peptides, noting that MOTS-c and growth hormone secretagogues are known to cause severe histamine and anti-drug antibody reactions. He strongly advises against large single doses or rushing injections, emphasizing instead the necessity of consulting medical professionals and understanding the high risk of severe systemic sensitivities associated with these substances.

    I’m fortunate (?) that I am allergic to shellfish. I told my doctor that I had a bad reaction when I was exposed to some shrimp and I got an EpiPen prescription that way.
