I wasn't aware that GHRPs were being targeted for drug testing. I assume that mass spec testing is going to be relatively expensive to perform and thus won't be common place but it is something to keep in mind if you are a competitor...
Determination of growth hormone secretagogue pralmorelin (GHRP-2) and its metabolite in human urine by liquid chromatography/electrospray ionization tandem mass spectrometry.
How long does it take for the GHRP-2 and AA-3 to be out of your system?Originally Posted by hax
I notice it says they were administered GHRP2 intravenously. I wonder if doing it Sub Q or IM would make its was to your urine?
Sport would be alot more interesting if they just let us use whatever drugs we liked...
Pretty much anything you put in your body will show up as metabolites in your urine, everything has a waste product, and urine is what we use to dispose of waste.
The half life of GHRPs is very short, isn't it?
I can't imagine this testing is all that common. I haven't seen much or any discussion of it publicly, and most drug tests don't even test for steroids, so I can't imagine peptide use is often tested.
This would only be of concern for anyone involved in a sport that is under WADA or one that uses WADA drug testing protocols. Your standard run of the mill drug testing for work or DOT will not do this type of testing.
Does anyone know how long ipamorelin or grf 1-29 stays in your system?
What is more important is how sensitive the assay they are using is.
What is interesting is that GHRP-2 is on WADA's list as an ORAL compound.
Identification of the growth-hormone-releasing peptide-2 (GHRP-2) in a nutritional supplement.
This should answer you questions.
"The elimination half-life of GHRP-2 after intravenous administration is only 25.2 to 41.4 min, suggesting that it is difficult to detect GHRP-2 in blood samples for doping control purposes."
"Thus, the excretion rate of unchanged GHRP-2 depends on individuals and the detection window is relatively shorter rather than that of AA-3. Despite the maximum concentration of AA-3 being one-tenth that of GHRP-2 (Table 4), AA-3 could be detected up to 24 h after administration in all ten volunteers."
whats the best GHRP to take to increase HGH ?? I am looking for a good combination to take to increase HGH and loose fat. Any help would be greatly appreciated !! I was going to take Triptorelin, but the side effects are terrible !!!
