it depends on what you consider better...
tbol is a steroid... lgd is a sarm... a steroid is going to be stronger but have more side effects... lgd will be very strong as it is without the side effects and recovery time... keepability of gains is much more likely with lgd... tbol will initially be stronger for sure, and you will likely get stronger and possibly bigger on it, but you will have far more sides, have a much more difficult time with recovering which makes it far more difficult to keep your gains...
you can get the best quality lgd at
