Has anyone bought from Peptronix Bio (PTB)?

Just paid $440 for tested r60, and $225 for tested r30. There's deals to be found. But uther is fast and well regarded- mine could very well take months to get here. 🤷‍♀️
You're not wrong. Uther is very user friendly, provides batch numbers and Jano reports for each batch sold. Thus, their higher prices on some items are probably well worth it.
