40mg of LGD?
I "cruised" on 4mg of OLUK LGD for 2.5 months and the results were nice and quite noticeable. In the past I ran it at 8-12mg and 12 is where it's at for me, and 8 was really nice too. I did plan on getting up to 16mg on future cycles but plans changed.
From talking to and watching some other users, 20mg is pushing the limits of where gains begin to get outweighted by side-effects. At that point in time you should be stacking with something else that compliments the SARM.
I seriously question whether a lot of those supplement companies actually meet their label claims... I remember seeing a supp. company in the past that had 25mg capsules of Ostarine and suggested dosing 2-3 caps per day. Seem real? Nah.
If people are dosing 20+ mg of LGD and getting no results, there's an issues with the legitimacy of what they're taking, they don't respond well to that compound, or they need to take a few months off to re-set their on-cycle expectations. After 4-5 months off, 4mg of LGD was a nice light dose that gave me noticeable increases in fullness and vascularity.
It's all perspective, I guess. If you're trying to get "jacked", I can see 22mg being worthwhile. If the pills are legit, I can't see a need to go higher than that. Nor would I recommend taking that much (30-40mg) of a drug that has not been extensively studied in humans.
Lastly, I responded really well to the OLUK LGD and I would equate 8-12mg of that to ~ 50-65mg of Halo. That's my personal experience, anyway.
