Study 1: Simultaneous quantification of TB-500 and its metabolites in in-vitro experiments and rats by UHPLC-Q-Exactive orbitrap MS/MS and their screening by wound healing activities in-vitro
Authors: Khandoker Asiqur Rahaman, Anca Raluca Muresan, Hophil Min, Junghyun Son, Hyung-Seop Han, Min-Jung Kang, Oh-Seung Kwon
Source: https://www.sciencedirect.com/science/article/pii/S1570023224000412
Scientific Findings
This study developed and validated a simultaneous analytical method for TB-500 and its metabolites using UHPLC-Q-Exactive orbitrap MS. The metabolism of TB-500 was investigated in human serum, various in-vitro enzyme systems, and in urine from rats. The biological activities of the parent compound and its metabolites were assessed via cytotoxicity and wound healing experiments in fibroblasts. The results indicated that Ac-LK was the primary metabolite in rats, while Ac-LKK was a long-term metabolite. No cytotoxicity was observed for the parent compound or its metabolites. Notably, only the metabolite Ac-LKKTE demonstrated significant wound healing activity compared to the control, suggesting that the reported therapeutic effects of TB-500 may be attributable to this metabolite rather than the parent form.
Plain English Interpretation
Scientists have developed a new method to measure TB-500 and its breakdown products in the body. TB-500 is a substance that is thought to help with healing. In this study, they looked at how TB-500 is broken down in human blood and in rats. They found that one of the breakdown products, called Ac-LKKTE, is actually what helps wounds to heal, not TB-500 itself. This is an important discovery because it could lead to new and better treatments for wounds in the future.
Study 2: Investigation of in vitro/ex vivo TB-500 metabolism, synthesis of relevant metabolites and detection limits in urine and plasma
Authors: P. Van Eenoo
Source: https://www.wada-ama.org/en/resources/scientific-research/investigation-vitroex-vivo-tb-500-metabolism-synthesis-relevant
Scientific Findings
This project aimed to characterize the human metabolism of TB-500 using in vitro (human liver microsomes and S9 fraction) and ex vivo (human plasma/serum) models. The study found that TB-500 undergoes serial cleavage at the C-terminus, while the N-terminal acetylation provides protection. The researchers synthesized three metabolites, TB-500 M(1-2), TB-500 M(1-3), and TB-500 M(1-5), and a deuterated internal standard (TB-500-d3). The limits of detection (LODs) for the synthesized metabolites were determined and implemented into a screening method for detecting peptides in urine, with LODs of 500 pg/mL for TB-500 M(1-2), 100 pg/mL for TB-500 M(1-3), and 50 pg/mL for TB-500 M(1-5).
Plain English Interpretation
Researchers studied how the human body breaks down TB-500, a substance sometimes used to enhance athletic performance. They used laboratory models of the human liver and blood to see what happens to TB-500. They found that the substance is broken down in a specific way, and they were able to create some of these breakdown products in the lab. This information was then used to develop a more sensitive test to detect TB-500 in urine, which is important for anti-doping efforts in sports.
Study 3: Utilizing Developmentally Essential Secreted Peptides Such as Thymosin Beta-4 to Remind the Adult Organs of Their Embryonic State—New Directions in Anti-Aging Regenerative Therapies
Authors: Klaudia Maar, Roland Hetenyi, Szabolcs Maar, Gabor Faskerti, Daniel Hanna, Balint Lippai, Aniko Takatsy, Ildiko Bock-Marquette
Source: https://pmc.ncbi.nlm.nih.gov/articles/PMC8228050/
Scientific Findings
This review discusses the role of Thymosin Beta-4 (TB4) in regenerative processes, particularly in the context of cardiac repair. The authors highlight their findings that external administration of TB4 promotes myocardial cell migration and survival in embryonic tissue in vitro. This effect is retained post-natally and is attributed to a direct effect on cardiac cells. The mechanism of action is partly explained by the activation of Integrin-Linked Kinase (ILK) and subsequent stimulation of Akt, which inhibits myocardial cell death. The review summarizes the growing body of evidence supporting the therapeutic potential of TB4 in cardiac regeneration and its potential to influence age-related changes in the heart and blood vessels.
Plain English Interpretation
This paper reviews the exciting potential of a naturally occurring molecule called Thymosin Beta-4 (TB4) to help our bodies heal and even reverse some of the effects of aging. The authors’ research has shown that TB4 can encourage heart cells to move and survive, which is crucial for repairing damage after a heart attack. They found that this happens because TB4 activates a specific chain of events inside the cells that prevents them from dying. This research suggests that TB4 could be a promising new treatment for heart disease and other age-related conditions, essentially ‘reminding’ our adult organs how to heal themselves like they did when we were embryos
Storage:
All of our manufacturing partners produce peptides using the Lyophilization (Freeze Drying) process, ensuring products maintain stability for shipping and storage for 12+ months.
In lyophilized form, they are shelf-stable for many weeks. However, for long-term storage, it is recommended to store them in the freezer.
We often hear concerns about the standard “discard after 28 days of first use” disclaimer. Don’t worry, this has nothing to do with studies regarding the efficacy of specific peptides. 28 days is the FDA requirement for producers of multi-use vials to prove their bacteriostatic maintains efficacy. This minimum requirement becomes the de facto standard.
In our experience, if you use proper sterile procedures and refrigerated storage, you can continue sampling from the same reconstituted vial for 3+ months.
Third-party testing
Peptide Partners is committed to providing high-purity peptides at wholesale prices by frequently auditing its manufacturing partners using third-party laboratories. Independent analysis is vital to ensuring the quality and authenticity of your research peptides. Never trust a supplier that doesn’t submit to third-party testing. Never trust a certification that cannot be independently verified. All of the certificates that we provide can be validated on the third-party laboratory’s website.
Each product description contains a Manufacturer ID corresponding to the producer of that product. The table below contains the most recent third-party analyses for all manufacturers and peptides listed on Peptide Partners.

Verifiable certificates
When obtaining research peptides, it is essential to validate the authenticity of the Certificate of Analysis (COA). Certificate fraud runs rampant throughout the research peptide supply community. The two most common forms are doctored images and stolen certificates. You can check for these two by making sure the third-party laboratory’s website shows that the certificate belongs to the supplier and the values haven’t been doctored. TrustPointe Analytics provides a few simple rules for verification:

Beware of fraudulent laboratories
Not only must one remain vigilant about potentially fraudulent certificates, one must also be aware that there are third-party laboratories whose results cannot be considered reliable or scientifically valid. Unfortunately, there is significant evidence to suggest that one of the most popular third-party testing labs does not use scientifically sound methodologies and, in some cases, has fabricated results. There isn’t an easy remedy for this problem, but when labs are particularly bad, there tend to be a lot of discussion threads on various social platforms.
Interpreting Endotoxin Results (via TrustPointe)
Our friends at TrustPointe have provided the following detailed explanation to help interpret the results of the endotoxin testing.
We use the Charles River Endosafe PTS system to test for bacterial endotoxins following USP <85> guidelines:
- USP <85> Bacterial Endotoxin Result:
Because it’s reported as “ - If a result is above the limit of detection of the cartridge, it will be reported as a number (without the “<“).
The following are suitability parameters that verify the system was working properly and the sample prep dilution is appropriate for accurate results. Peptides often interfere with endotoxin detection due to their tendency to bind or mask endotoxins, which can lead to inaccurate low results. To overcome this, samples are typically tested at a large dilution to reduce matrix interference and ensure reliable recovery and detection in compliance with USP <85>. If the dilution is not correct, the run will fail suitability and we’ll need to adjust the dilution to ensure accurate results. We provide the suitability data to customers for transparency and so they can be confident in the results.
USP <85> Sample CV %:
- CV stands for coefficient of variation, a measure of repeatability.
- For our lab, CV has to be <25% or the result to be considered valid
USP <85> Spike CV %:
- This refers to the precision of the positive control (spiked sample).
- Again, for our lab CV has to be <25% or the result to be considered valid
USP <85> Spike Recovery
- This tells us how much of the known endotoxin spike was recovered from your sample.
- The acceptable range is 50–200% per USP <85>
