The mg dose in units but not mL is effectively useless and can potentially lead to dangerous errors.
Yes, they all say that, but most aren't stupid enough to offer a calculator on their website clearly intended for human use. Take a look at this: https://www.dea.gov/press-releases/...nts-charged-operating-websites-illegally-sell and pay special attention to where it says "In addition, the labeling on the drugs sold and delivered to customers falsely stated that the drugs were “research compounds” and/or “not for human consumption.” Contrary to these representations, Fields and Mahan knew and intended that the drugs they sold were for human use, and through emails and posts on the Pinned Aminos Facebook group, they provided customers with information on the health benefits of the drugs they sold and directions on dosage."
If a peptide vendor is not smart enough to avoid admitting that their sales are intended for human use by having a calculator on their website (or selling syringes & BAC water), then I wouldn't trust their product. Plus when outfits like this do get shut down, the feds now have their customer list.
