Yes, Ibutamoren MK 677 is legal. Its legality varies from country to country and or region to region. As of 2017, it was still in the preclinical stages of development and for the purpose of growth hormone deficiency. It has not been approved in the US and soon it will be. The problem here is not legality but simply that of approval. YK11 is another powerful muscle mass drug and soon to be approved worldwide. Buy with confidence and try to avoid purchasing fake.
In Australia, SARMS are a presciption only medicines. However, being in possession of Ligandrol (LGD 4033) without the proper and lawful authority is illegal.
The Australian Therapeuthic Goods Administrtor (TGA) classifies LGD 4033 as illegal if found without a prescription. However, Ligandrol is available through out Australia. If not, feel free to import it from another part of the world.
Some States in the US consider LGD 4033 as a banned compound because it mimicks the effects of steriods though no side effects have been detected.
However, on the 23rd October 2017, a Missouri national supplement company known as “Infantry Lab” received a formal warning from FDA against the distribution and supply of SARMS or its compounds.
