Is beta-2 receptor competition possible?

[magic32]

Some people begin Clen cycles, yet still take their ECA stack for the mule-like kick in the gym.

Here’s my question:
If both Clen which has beta-2 receptor selectivity, and the ECA stack which stimulates the beta receptors indiscriminately are present, would they negate or minimize each other’s absorption?

And if so, would one be more limited than the other? For example, would the ECA kick be minimized or completely negated, but the Clen fully absorbed, vice versa, or some combination of effects?

From my understanding they can be taken concurrently np, but bump for more answers
