>I wonder if what I'm getting has any negative long term effects. Based on the reagents used in MK-677's synthesis, yes there certainly could be. A customer of ours wrote us saying that he tried another vendor's MK-677,

Sorry, for some reason I saw TLR instead of IRC. I am not calling IRC bastards. I would stop using their MK, based on some testing I just did. However, they are working with me on figuring out what the deal is. Not sure

Could be a different batch, but I would check with them.

No, this batch was a different impurity. There are two of them. One I think is ethyl acetate. The other I am not sure about. You should be able to strongly smell the ethyl acetate. It smells very similar to acetone, or n

As soon as we get a good batch, it will be back up on the site. We always have more batches coming in. It's them being pure that is the issue.

No, don't consume it. The CDC says that repeated exposure of 4,450ppm resulted in damage to liver and kidneys in rabbits. That's only about .5%. The impurities our HPLC are seeing are about 3% each. I would not risk it.

The ethyl acetate could be evaporated off, sure. Usually that would be done in a vacuum desiccator or vacuum oven. However, the other impurity I am not sure of. Even if you evaporated all the ethyl acetate, you are still

What temperature did you set the oven to for evaporation? 175F for 2 hours like you planned?

I might try oven evaporating it, then rerunning it through the HPLC again.

Before I answer, let me just say the following statement in the assessment made me laugh: >Six weeks after the initial dosing, 10 rats/sex were subjected to interim sacrifice while the remaining rats continued on the do

Roger that.

My pleasure! I've been working really hard to get valid and reproducible HPLC methods for MK-677. Most labs seem to kludge together methods to get the results they want to see. I've had the supplier tell us to just dilu

We just discontinued all SARMs and MK-677, unfortunately. However, the labs are still putting our shitty impure synths. Still have not gotten one that is acceptable.
