ADDITIONAL INFORMATION ON THE PROHIBITED SUBSTANCE
LGD-4033 is promoted as a selective non-steroidal anabolic agent. It is claimed to be a substance that induces muscle (and bone) growth without the side effects associated with steroid use. However, information on the safety of LGD-4033 is scarce due to a lack of medium and long-term clinical trials - hence the medium and long-term health impacts are unknown.
It should be noted that a number of Selective Androgen Receptor Modulators (SARMs) have associated health-risks, particularly for the heart and liver.
There are a number of health concerns for substances listed under Class S2 (Peptide Hormones, Growth Factors and Related Substances, and Mimetics). Long-term studies in the use of growth hormone releasing peptides (GHRPs) have not been performed as the majority available on the internet have not been approved for human use. As such, they are considered a Schedule 10 poison and are prohibited to sell, supply and use.
