    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.

    What labs are we trusting today? Who are we not trusting? I just saw ethos as a lab on Glacier and haven’t heard of this one before.


    @Randy exactly, a low of 10.1mg and a high of 12.9mg. That’s over a 20% differential….

    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

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.

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?

    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?

    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.

    MHC was my first peptide purchase, and I genuinely like what Max has built. Even though I mostly use grey-market sources and Nexaph now, there are still a few retail resellers I keep an eye on, MHC included.

    What has kept me from ordering is the pricing. Of the companies I follow, they tend to be among the highest-priced. Their platform has always been strong testing, but lately it feels like more and more testing is being added to justify that premium.

    I’m not sure it necessarily adds enough value for me personally. Once purity and endotoxin are confirmed, I’m usually comfortable. Sterility testing is a plus, but I have rarely seen a failure reported and understand true failures should be uncommon. The same goes for heavy metals, since they generally are not part of peptide production. Residual-solvent testing is newer to me, so I’m still open to learning more about its value.

    With the growing availability of well-tested grey-market options, I think the question becomes whether the additional retail testing justifies the price difference.

    How does everyone else feel?


    Yeah i guess we want best testing but yes while we see alot of prices come down with competition some may keep higher price with more testing. My issue, Some prices ie tirz i can get compounded pharma grade for few bucks more than the top peptide places Even with testing i have been on prescription tesa/ipa, tirz, bpc, semax,motsc. And yet i get same peps that at times have zero effect or far less meaning it was junk or lower qty of actual active ingredient. And these are from some top rated peptide places. At point are the peptide places worth it.. if they dont clean up the crooks and have 100% tested legitinate stuff, as coumpounding becomes more available for common peps, as long as price doesnt sky rocket there will be some give and take.

    @iamsomebody said: Thank you for this, my expectations were no where near the results! Now do freeze, thaw , freeze thaw. Does the freezing and thawing Degrade the peptides as much as we think? How many times can they be frozen and thawed before they reach 95% or 90%? This would be a great test. Also testing other peps besides Reta/Tirz to know definitively which peps are the most sensitive.

    So I'm already on subq GHK-Cu and I'm looking to add a topical form of ghk-cu as well. What brands, serums, or formulations do you guys recommend and what has worked for you?
    I was looking at https://www.avasresearch.com/


    Let us know if you see any difference. I’m especially curious about Snap 8. From my understanding it sort of has the effects of Botox? So I’m interested in what you experience using it topically.

    It’s easy to slap a label on a peptide vial, send it out for testing, and sell it. I don’t think any vendor is really lacking the ability to do that.

    What I think separates vendors, though, isn’t just the products themselves. It’s their customer service, how they handle challenging inquiries, their demeanor and attitude toward customers, and how they resolve issues in a way that leaves both sides satisfied.

    We always talk about which vendors have the best products, but in your opinion, which vendor really goes above and beyond when it comes to customer service and handling problems or difficult situations?


    I had a great experience with Verified Peptides on two occasions. One time they sent me Selank instead of Semax,. I contacted them and not only received my Semax, they gave me a $100 credit and let me keep the Selank. On another occasion, after ordering Mots-c, but before it arrived, they contacted me to let me know that they had mislabeled the vials, and the amount per vial was twice what the label indicated. I only paid for the lower amount, but got to keep the extra for free.

    I like S1 also. I used to buy my SS-31 50mg vials from them as I found their pricing to be great. But they use Freedom for COA on the SS-31. If they change labs to someone better, I would like to continue buying from them. They are a great vendor.
