For instance I can say MedfitRX Methyltrienolone Nasal Spray is legit and strong as all get-out.
I can tell you it's got 0.75mg per six sprays, which is a full proper
swimfan65 dose of methyl tren.
But I can't tell you where to buy it because the stores that carry it aren't sponsors. You just have to look, and since it's an OTC product, it's easy to find.
you can try the Aggressive Labz MK Elite product, or if you like MA Research the board sponsor has Somatozine,
Mk677 is a very popular item on pure RC sites. Almost always out of stock when I'm browsing.
You can also try Alpha Breed brand SARMS found OTC, they have an MK product.
MedFit, unfortunately, does not make a pure MK product. They feature it in many stacks, though.
There is also a bcaa product featuring mk677 out there. Carnage it's called.
