    So I'm on the east coast with this potential huge storm coming and of course I'm on vacation with all my peps in my freezer chest at home.. if I lose power and all my stuff thaws out how bad is this? Everything is still powder so I know that helps but I know the freeze thaw cycle is not great


    @e_kantor2 My road trip to New York just got cancelled so you’re all going to have to pick it up this weekend and keep me entertained.

    hello, I was wondering where you guys recommend buying Hospira BAC water from. Don't know if there is a site that offers discounts from here that sells Hospira Bac water. Does anyone have any takes on where to find the cheapest Hospira BAC water? Thanks, guys


    @Snake-Pepskin I agree, but it hasn't been that price since 2024. It is greed... To tell you the truth, I have spent a fortune on all this peptide stuff. So it was just one more thing I had to buy, even at the ridiculous price. I could not risk not being able to get it. I haven't felt this good in the last 20 years, so it is a small price to pay for me. I was doing really bad the last five years or so. I was struggling just to stay alive. I figure it was just how it was going to be since the doctors told me years ago I only had a few years left to live. Now I actually feel pretty good again and hope I still continue to improve.

    I started writing a small post on another thread and this just kept getting longer. Hope this can inspire someone at any point on their journey.

    10 years ago I was 387 pounds. Addicted. Depressed. Self centered and miserable. Something needed to change but it didnt. Atleast not for another 3 years.

    7 years ago I kicked the drugs and alcohol. In the 4 years after that my weight continued fluctuating between 260 and 330 pounds.

    3 years ago I decided to get serious about my health. To do so I was going to have to deal with my first and most insidious addiction. Food. I decided to try Tirzepitide at the urging of my doctor and for the first time in my life the food noise quieted. I was able to hit calorie goals and after a ton of research I knew I had to resistance train. I have now been training for 3 years.

    This March I was down to 235 pounds and after a 4 month break from Tirzepitide I started Reta. I just hit 200 pounds. I cant believe it.

    So what were the last 3 years like? Every pound lost along this journey my feet and back hurt less. I had more energy. I was eating better so I decided why not compound that by walking and moving. That led to more weight lost. Every thing I read and all the videos that I watched stressed the need to resistance train. So I wondered what would happen if I added that too. Turns out. Everything. Everything would happen. Weight loss acceleration. Strength increase. Visceral fat loss. I had a 46 inch waist. Im down to a 32.

    Once I had some small succeesses I wanted more. Each goal achieved built on the next. The GLPs gave me the reduction in food noise and calorie restriction. The food tracking gave me the data and discipline. The walking raised my TDEE. Now Im even doing some running. 3-5 days a week Im lifting weights. Tracking every workout. Progressive over load. Deload. Run it again. I have never been in better shape. Better health or happier. Im living a life beyond my wildest dreams.

    If you are starting a journey or are in the middle of one I have a challenge for you. What if you did everything. Everything you know you should do and really want to do but haven't.

    You tracked what your eating and hit your daily calorie target. Hit that elusive protein goal. Went to the gym consistently. Hit your daily step goal. Figured out how to sleep more and consistently. Drank water. Maybe even a peptide or 10. Lol

    What if you did that? What would future you think in 30 days, 6 months or 3 years?


    Hit an "Unrealistic Goal". Got on the scale today and I'm 198 pounds. Seeing the scale go under 200 pounds for the first time in 30+ years is amazing. I was a teenager the last time I was under 200 pounds. This felt so unrealistic at the beginning of all of this but here we are. Coming to the end of the first 30 days of a 90 recomp. My daily steps have increased from 5k-8k a day up to a minimum of 11k a day. Im getting up and doing 2 miles before work. Running multiple days a week. Resistance training 4 days a week. The level of intensity and discipline needed to continue hitting these goals has increased immensely. Its really hard and challenging but so rewarding. So Happy Friday. Set some unrealistic goals for this Fall and do what you know needs to be done to hit them.

    Does anyone know what name the sell Retatrutide under?


  • EXTROPIANE

    @Shaqdiesel it’s actually worse on the legit retail side. People take their doc’s word ((or lack thereof)) as Bible sent. Doctors don’t know any more than you or I about this stuff, actually less. People don’t research anything there either. They don’t know crap about diet, macros, dosages, protein, nothin’z. Then they’re butthurt when they pukin and shittin with burps and reflux. Then they’re butthurt and sue the manufacturer.

    Ive been taking reta for around 6 months now I started at 198 and currently 165. I still need 5 more lbs for my goal weight. What is the best way to leave reta or should I keep taking it but just in lower doses? I just pumped up to 4mg a week and have 3 dosages left on my vile.


    Similar...I've been on Reta since late Feb, and finally hit my goal weight 3 weeks ago (165 down from 217). I only maxed out at 4mg/week and lowered my dose to 3.5mg last week and this week. Will plan to continue reducing by .5mg every couple of weeks.

    Have any of you had bad reactions with Semax and caffeine? Started researching semax. Had morning coffee with a shot of espresso and it was a bad day. Highly highly irritable and just all around bad attitude. Had to apologize to multiple people. Very very out of character.

    Hi all,

    I'm looking for any guidance, suggestions, and experience for researching nad+ and glutathione (Korean pharma gluta 1200mg). I do not have access or time for any IV protocols so I was planning to research these as intramuscular. I have done some previous research with 600-700mg injectable carnitine doses so a bit of PIP is tolerable for this research.

    I have seen varying recommendations all over the place for daily to 3x weekly to once a week at all kinds of dosages and was just looking for any input and experience you will have had.

    Thanks!


    @anotherdad My pleasure.

    Has anyone bought from these guys out of Columbus?

    Anyone ever have their stuff tested and if so who would be good to test BAC Water?

    Hey yall, as you know I am fairly active in this community, and many steer clear of us due to low pricing and basic testing, we want to change that, we are thinking of adding sterility, endotoxins, and conformity over at vanguard and would love some feedback!

    It is costly but we would love to draw in a new crowd and also continue safe research at a reasonable cost, let us know your thoughts

Is that the same Studz?? Is this you? https://www.tiktok.com/@studzpepofficial4/video/7667181387719494942?is_from_webapp=1&sender_device=pc Does it really matter? As long as he's providing good service, using a quality lab, and delivering said product, I don't really care how old he is or what he does in his own life. I imagine a lot of vendors are no different than the guy in the video maybe just a bit older. He is literally using an address that doesn't exist on his website. His Discord is just him dropping random pricing with literally zero way to actually buy anything. Its a scam to get people talking. Thats it. [image: 1790112865637-b100ed1d-7216-466a-81b6-34fb17ae7cea-image.jpeg] Not sure where you get its a scam. There have been people on here that have bought from his site and received what they ordered. I mean the wholesale side of their business. Clearly they sell singles and have been on Tiktok for awhile.

    Here's a quick comparison of what's left behind in a cart after each pen version has pushed to its limit.

    If you really need to get every last drop out, just use a syringe to pull out the remaining; never use a spacer.

    Do not use a spacer; it will most certainly break the pen. Been there, done that. Listen to @randy. They get stuck in that position and even if you manage to get the plunger back down, it will never be accurate again.

    Hello folks. New to the forum and just secured my first batch of BPC-157/TB-500 , “Wolverine” . Gonna run a cycle to help heal from recent neck surgery. (ACDF) I did verify the batch the Freedom diagnostics and every think looks good. But still have reservations on sterility. So far the customer service has been great with the getting back to me promptly. Any one have any helpful input for my first go at this?

    I bought two vials of Hospira bacteriostatic water from PeptideTest.com on 9/4/2026. Then on 9/17, I picked up two more from Southern Aminos during their $13 sale.

    What I found interesting is that both sets have the QR code on the metal crimp, and they all have the exact same lot number and expiration date.

    a00d689c-c49a-4f2b-b6c6-a5fd3bf1d939-IMG20260922150453.jpg

    In the photo, the two unopened vials on the left are from Southern Aminos, and the two on the right are from PeptideTest.

    Lot: NT9150
    Expiration: 2028-FEB-29

    My understanding is that Southern Aminos is in California, while PeptideTest is in Tennessee, so I was surprised that purchases from two different vendors ended up coming from the same Hospira lot.

    Does anyone know how large Hospira production lots typically are? I'm curious how widely a single lot like this gets distributed.


    In addition to the other comments, I imagine both sites buy wholesale from Hospira by the pallet. This is just the newest batch. The bottle I bought a few months ago "expire" in late 2028.
