Andarine + Methyltestosterone Buccal
Methyltestosterone Buccal brand names: Oreton Buccal, Android 5.
Andarine has a moderate interaction with Methyltestosterone Buccal. Due to its androgenic properties, Andarine (S-4) may theoretically interact with other androgenic drugs, potentially increasing the risk of side effects associated with androgenic activity (source: https://pubmed.ncbi.nlm.nih.gov/12604714/).

Here is the interaction we found between these two, with the evidence behind it.
Androgens
Why this applies to Methyltestosterone Buccal
Methyltestosterone Buccal falls under Androgens — the group Andarine interacts with.
Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.
Here's the simple version: both Andarine and methyltestosterone act on the same androgen receptors that testosterone normally uses. So instead of one source of hormone activity, you'd have two pushing in the same direction. That stacking can amplify the very effects methyltestosterone already causes, like acne, oily skin, hair loss or unwanted hair growth, voice changes, mood swings or irritability, increased sex drive, and strain on the liver (methyltestosterone is known to be tough on the liver).
To be fair, this concern is mostly theoretical and the evidence is limited. But Andarine isn't an approved or legal supplement, and its safety in people isn't really known. I wouldn't combine these. Please talk with your doctor or pharmacist before changing anything.

From our pharmacist’s overview on the Methyltestosterone Buccal page
“Methyltestosterone buccal (Oreton Buccal, Android 5) is an androgen that can strain the liver on its own, and 38 of the 73 supplements on this list can add to that liver stress, so real care is warranted. Two of the four major entries are alcohol itself, beer and wine, since drinking on top of a liver-taxing drug raises the risk of dam…”

Andarine (S-4) is a synthetic selective androgen receptor modulator (SARM) that is not approved by the FDA for human use and is banned in sports. It is not a legal dietary supplement ingredient, its long-term safety in people is unknown, and reported side effects include vision changes and possible liver and hormone problems. Because of these risks and its illegal status, we do not recommend using it.
