AOD 9604 Peptide

AOD 9604 is a modified peptide initially developed as an offshoot in obesity research. It modifies the peptide Fragment 176-191 of the growth hormone hGH by adding a tyrosine residue to the N-terminus. The proposed mode of action of AOD 9604 has been suggested by researchers to be restricted to promoting lipolysis, thus linking the synthetic compound to obesity research.[1] The peptide does not appear to affect levels of insulin or IGF1 in studies thus far; therefore, it does not appear to trigger diabetes development or induce glucose intolerance in test models, though further studies are necessary to explore this aspect.[2]


Other Known Titles: AOD-9604

Molecular Weight: 1815.1 g/mol

Sequence: Tyr-Leu-Arg-Ile-Val-Gln-Cys-Arg-Ser-Val-Glu-Gly-Ser-Cys-Gly-Phe

AOD 9604 Research

AOD 9604 Structure
Scientists hypothesize that different parts of the hGH molecule may possess different properties and induce different effects in test models.[3] It has been suggested that only the last 15 amino acids may mediate any fat-burning potential of the hormone. The fragment was initially named hGH 177-191 and was subsequently modified by adding tyrosine to create AOD 9401, potentially to help stabilize the molecule. This modification led to the production of a 16-amino acid fragment called AOD 9604.[4] Interestingly, the researchers comment, “AOD 9604 does not interact with the hGH receptor.” This modification may have made the hGH Fragment 176-191 relatively more stable than other peptides.

AOD 9604 Mechanism of Action
AOD 9604 has mainly been studied in murine models, and significant experiments have involved relatively large amounts of AOD 9604.[5] These experiments reportedly resulted in a 50% reduction in weight following exposure to the research models. However, it is important to note that the fragment appears to lack any other associated action of hGH, such as a potential increase of IGF-1 (insulin-like growth factor-1), insulin resistance, or cell proliferation. Therefore, the compound may not possess the potential muscle-preserving and anabolic action typically associated with growth hormones. Nevertheless, it appears that AOD 9604 may stimulate weight loss through mechanisms similar to hGH, as it may trigger various cellular pathways that might lead to the release of fatty acids from adipose cells.

Additionally, researchers have posited that the peptide may affect the activity of lipases, a group of enzymes that prevent the return of fat to adipose tissues.[6] It is worth noting that AOD 9604 does not appear to affect natural hGH production and does not appear to act as a growth hormone secretagogue. Moreover, it does not appear to impact hunger hormone signaling to either increase or decrease appetite. Murine models comparing AOD 9604 and hGH have reported different outcomes in lean and obese cases.[4] In lean murine models, hGH appears to increase lean body mass, whereas AOD 9604 or a placebo did not appear to produce the same action. Hence, researchers have speculated that AOD 9604 may not be effective in increasing the size of muscle cells and contributing to muscle hypertrophy. However, in obese murine models, both hGH and AOD 9604 appear to exert a weight loss potential. The scientists also commented that there was an apparent 40% reduction in adipose tissue in the hGH group compared to 28% with AOD 9604.

Therefore, experiments suggest that AOD 9604 may hold reduced potential compared to hGH in stimulating the release of fats from adipose cells.[7] The researchers also posit that “the lipolytic actions of both hGH and AOD 9604 are not mediated directly through the β3-AR although both compounds increase β3-AR expression, which may subsequently contribute to enhanced lipolytic sensitivity.” Growth hormone likely promotes a greater release of fats from adipose cells due to its proposed impact on insulin resistance. By reducing glucose uptake, it may force cells to potentially utilize more fat instead. In contrast, the fragment AOD 9604 does not appear to increase insulin resistance. Additionally, anecdotal data suggests that AOD 9604 may potentially offer some impact, including modest improvements in cholesterol levels and insulin sensitivity, but it is yet to be confirmed by murine models.

AOD 9604 and Obesity
AOD 9604 has been brought into clinical trials with the objective of targeting obesity using a peptide similar to hGH. Phase 2b clinical trials conducted on 300 obese test subjects in Australia observed that the peptide appeared to result in consistent weight loss over 12 weeks when introduced once daily.[8] The rate of weight reduction in test subjects was consistently compared to the placebo cohort, and weight loss appeared to hold steady over the entire study period. This observation indicated that the peptide is unlikely to generate resistance, and thus continued influence of the peptide might result in a pronounced effect. Study in this area is ongoing. Researchers have also utilized mice models to explore the underlying mechanism of AOD 9604.

An initial hypothesis proposed that AOD 9604 may bind and activate β-3-adrenergic receptors, which are present on the surface of white adipose tissues. Upon binding to the cognate receptors, the peptide may trigger downstream signaling, which may mobilize the fat cells from storage mode to a usable state by enhancing the rate of metabolism. Interestingly, mice genetically mutated in β-3-adrenergic receptors underwent fat loss, possibly through apoptosis of the white adipose tissues.

AOD 9604 and Cardiac Disease
AOD 9604 may host the potential to improve cardiac function indirectly by mobilizing fat and reducing obesity. The peptide may reduce the chances of cardiac disease induced by obesity. Apart from its proposed principal function of decreasing fat burden, research teams have suggested other mechanisms by which the peptide might improve cardiac conditions. These pathways are independent of β-3-adrenergic receptors and appear to improve general metabolism, improving cardiac function.[9]

AOD 9604 and Joints
Research suggests that AOD 9604 may influence arthritic joints in rabbits, and may have contributed to an improvement in pain perception and decreased movement disability.[10] Researchers have speculated that AOD 9604 may promote the growth of cartilage tissue in the arthritic joints but have yet to fully investigate this hypothesis. Experimental examination and microscopic cartilage structure analysis in affected joints have indicated positive results upon AOD 9604 influence in osteoarthritis test subjects.

    Fast delivery and simple purchase. I haven’t gotten around to evaluating the quality of the goods yet. I have heard through the grape vine that they have some very nice products that have shown a difference in many others researches.

  20. David Shwartz

    This was recommended to me by a person I work with and since I started purchasing from you guys I never switched suppliers again

  21. Nathanael R. Odom

    Customer service is as great as they said. I ran into a problem this week with the company(shocker). They sent me only three of my products instead of the five that I ordered. That’s a problem. I got ahold of one of their representatives and not going to lie I was really frustrated. The guy on the other end understood why and explained this is not a common occurrence at all. Nevertheless, they made sure to take care of it right away and refunded me for the missing products as well as give me a discount for the next purchase. I got my missing products within a few days. The whole process was a headache but they made up for it. I’m going to give them a try again and hopefully no more mishaps.

  22. Alex Morales

    Been purchasing products from Biotech since August! hasn’t seemed to fail me yet

  23. Joanna Marszalek

    Taylor is awesome, always helpful, and knows their stuff!! The product was out of stock and they were able to recommend a peptide that’s a substitute for the one I needed.

  24. Shiv Patel

    Had a small issue with getting the products in time due to traveling all the way to India. I am happy to report that the peptides were no ruined in the process. Packaged perfectly

  25. Leo Murphy

    Always amazed with the quality. Purity checks out everytime. Peptides are as true as they can be.

  26. Harry Gagnon

    Have encountered a few times where peptides were broken but didn’t say anything as it was just one vial out of the bunch so it didn’t effect me too much. This morning when I opened my package almost all the peptide were shattered. Must have been a rough delivery process. Had to contact them but was not worried as i’ve seen some remarks about this happening to others. They didn’t even ask me for proof, Taylor just asked for the order number and confirmed the address.

  27. Emily Roy

    Just put in my order with them again. I have been shopping with them for the past year. I have not had one bad experience with them. Really good company!

  28. Christopher Adams

    They are a decent site to get peptides. Usually in stock of everything you need. Did notice the abundance of peptides as well. Haven’t seen a site with this many products in stock before.

  29. Susan Stivalo

    Taylor is great at what they do. In my bundle I put in the wrong peptide. Sent a quick email to Taylor and they were able to make the corrections happen.

  30. Omar Sanchez

    Got 3 free bac waters instead of the 2 that were promised! Nice surprise

  31. Ken Walters

    Taylor was amazing at answering all questions and handleing all my needs. They knew all the peptides and orders which was refreshing as you call some other places and the employees don’t know much. Customer service can’t be beat.

    Storage life is great, just follow the directions and you should be good for the time being. I wouldn’t worry too much about it as it’s pretty easy to store it correctly if you literally just follow the directions of what to do.

  44. Adam Bilmes

    Company is great, Peptides are even better.

  45. Ziad Hijazi

    I had placed a rushed order for my peptides and they arrived on time! No peptides were missing and they even through in a free Bac water on the house. Absolutely love their service and work ethic.

  46. Russell posin

    Amazing peptide quality

  47. Jon Walters

    The researchers at my lab love the peptides from biotech! We’ve made it out sole provider. If a shipping issue or a product is missing they make it an easy and stress free process to get a hold of them AND they handle it quickly. I have never had to call twice to fix an issue, they get the job done right away the correct way unlike so many other companies!

  48. Hiep Dang

    Appreciate the frequent emails and promos!

  49. Hal Louis

    Peptides met all expectation in regards to quality and pureness!

  50. Brandon Nguyen

    Not too difficult to store, just need to follow directions and you’re good to go. Seems like people have issues with it sometimes but even the call center here will tell you just follow the exact directions and you should be good.

  51. Jason Sirak

    Get a sense of quality over quantity with them. Did notice they’re adding some new peptides to the site as well though!!

  52. Gabby Helton

    I was recommened here by a work friend, can’t wait to test these peptides out, I’ve been told my research will see some good changes.

  53. Vic Carrizalez

    Swicthed over to biotech after hearing great stuff about the service and peptides. They don’t dissapoint!

  54. Yu Ning

    Very pure, very high end stuff

  55. Andy Peters

    Got the products shipped all the way here in Canada. Peptides have arrived safley and in great condition. Wouldn’t say they came from the US.

  56. George T.

    I wish their sales were a bit better. Feel like the discount doesn’t do much of a difference on the end total.

  57. Karly Lucht

    Got my stuff within 48 hours of ordering.

  58. Adam Jewell

    Had no issues getting them out here in Canada! In the past with other companies its taken a few weeks to get them in but only took a little less than a week with biotech.

  59. AL Armstrong

    Would purchase from them again!

  60. Yvonne Mercedes

    Got my package when estimated and everything inside was properly protected. Box even has fragile written on it on a red tag so nice to know they’re doing all they can to prevent anything from going wrong.

  61. Travis Olinger

    Was scared the peptides could be effected by the heat but everything looks good! Peptides came as safely as they possibly could. Heat did not seem to do anything to it and they work as they typically should.

  62. Amy Trahan

    Discounts are great, and they give them pretty often. It’s also pretty nice that they don’t expire for a while so you can use it up till a few months. I also noticed I can use it on sale peptides as well which is always great.

  63. Teria Harris

    I was a bit concerned when initially ordering. I must say the products are fantastic! I am also very impressed with how quickly I received them. This is the new spot for all my peptide needs.
