Need some pro tips

[HoldMyBeer]

I bought some SARMs from the local supplement store.
I got mk2866 and rad140.
The problem is, the MK2866 is spelled ostErine (emphasizing the e, not an a) and the chemical composition listed on the back is missing the 2-hydroxy
Should be:
Ostarine(MK-2866); N-(4-cyano-3-(trifluoromethyl)phenyl)-3-(4-cyanophenoxy)-2-hydroxy-2-methylpropanamide; 1202044-20-9; Ostarine?MK2866)

The rad 140 seems alright. Chemical composition matches up with what I could find online.

Neither says "For research purposes only" on it. mfg by: Bio-Gen Innovations

Bought a bottle of liquid clomiphene "for research purposes only" for a short pct after.

What are the chances I got legit stuff?

Also,
The "osterine" suggests 3 caps per day (20mg per), the dude at the counter suggested 2 per day, and everything I read online suggests 20mg per day. Dont know how much I should take.
The rad140 says 3 per day, 10mg per. Dude at store says twice a day. Online suggests 20 mg/day. Don't know how much I should take.

Thoughts anyone?
