Hi, FIrst of all you need to put your labrat on a diet. Thats is the foremost action to take if you want to take down your rat`s bodyfat %. Furthermore adjust your training with low weights and high reps. This will make him lean. Then comes the Sarms into play and indeed, S4 is what your rat needs to get lean and get his bodyfat lower. You could think of a combo with GW501516 CARDARINE , which even more lowers bodyfat and will help massively with his cardio to burn even more fat! Only give him the LGD if you want him to go the other way around, to bulk. LGD is a killer bulker and with a shiltload of calories he will gain like a madrat. Hope this helps.
The dosages should be between 2.5 to 10mg per day during the clinical studies but take proper diet is mandatory with any health supplement.
