AF-M315E, LMP-103S, are 2 of the newer green mono propellants that Rocket Labs probably uses, these are a lot less toxic and hazardous than hydrazine. Even though they are lass toxic and hazardous than hydrazine, they still are toxic and energetic.

Monopropellant LMP-103S is:
60-65 % Ammonium DiNitramide (ADN) ,
15-20 % Methanol ,
3-6 % Ammonia
and the balance Water (by weight).
I doubt ADN or the mixture LMP-1035S would be made available for our hobby visit: https://ndiastorage.blob.core.usgov...e/8Asjoberg.pdf

Monopropellant AF-M315E is a hydroxylammonium nitrate (HAN, NH3OHNO3) fuel/oxidizer blend, composed of:
65-75 % hydroxylammonium nitrate (HAN),
0-1% 2,2'-dipyridy,
0.5-10 % Ammonium Nitrate,
5-15 % 1,2,4-triazole,
0-10% 1H-pyrazole
and the balance is 0.5-10% Water.
I doubt HAN or the mixture AF-M315E would be made available for our hobby visit: https://static1.squarespace.com/sta...M+Mod+3+SDS.pdf

Hydroxylammonium nitrate, itself is a dense energetic ionic liquid, the hydroxylamine portion is a known irritant and mutagen. As a chemist I have worked with both hydrazine and hydroxylamine and will definitely say hydroxylamine salts are much easier of the 2 to work with as long as you don't heat them up.
