Purchase Peptides LR3

The results are nearly identical to Extreme, Maxim, and Ergo USA LR3. I would rate these 4 LR3 as excellent LR3. You can see in the mass spec that we have a nice tall peak at 9100 range with a tiny bump in the 9400 range which again is because of the tiny amount of histidine tag present. The rest of the mass spec looks very clean without any other impurities. The amino acid analysis also looks very good with total of 0.95mg of total LR3 in the vial which is pretty as much as good as it gets.

My thoughts:


First i am pretty impressed that we even had any damn LR3 in any of these vials cause i was very skeptical to begin with despite the source. I do not think any of them are "bad." I think it is matter of good or better. I have already contacted OstaPresident and sent him the raw data and have even offered to setup so he can send a vial directly to lab for analysis. I dont want anyone to think there are any fishy stuff going on.

SRC by pure analysis looks very good however the fact that they are the most expensive out of the bunch and had only 0.8mg which is about 20% short of advertised makes them great but very pricey. You pretty much have to add 20% to their price to get a real price on what 1.0mg would cost.

I think Extreme, Maxim and Purchase Peptide have a great product. We know for sure we have LR3 and pretty much as close as to 1.0mg as you can get. The histidine is very small when you look at % of amino acid involved. The lab tells me less then 5-8% may be His-tagged. So even if you subtract 8% from 0.95mg you still end up with more LR3 that is untagged and probably at a better price. It was revealed and confirmed by Extreme that Ergo's USA LR3 is the same as Extreme and they buy from exact same source so i did not want to spend another $400 to test the exact same product again since Extreme's tested so good.

Osta unfortunately had the peak at 7000 which neither lab or i can explain and had only 0.73mg of total protein in the vial. I am hoping they discuss this with their manufacturer and come back with a better batch to test or we can re-do the test if they would like.

Please do not turn this into mud slinging etc. The data is clear and evident. If you have direct questions about interpretations of the data etc please feel free to ask and i will respond.

At this point my job with LR3 is done. I think there are a lot of great options out there. I would like to turn my attention to DES. In my humble opinion, DES is even a better compound than LR3 but much more difficult to produce. We are completely out of funds for Des testing. If members would like to donate it would be great so we can do similar testing for DES. These tests normally cost $1000-1500 per sample but due to my pharma connections, the lab is doing it at cost which comes to ~400 when counting shipping. If members would like to donate please message me so i can send you paypal address so we can carry same testing with DES.

This is great info! Helps to keep the sponsors quality control in check.

I only wish the same could be done for gear too. Would be great to be able to see what they are offering in the way of quality.

Can't wait to see more of these done!

New to the boards and this sort of quality research is what drew me here. Nice to see some of the major suppliers of research peptides check out! Great work!
