Im just currios on the boards opinion on this, feel free to post your idea:
Say you did a 15 weeks cycle of a low end vet gear like Brovel of Test E
and your twin brother with the same stats/diet/training/gens,
did the same cycle of Test E
with a high grade human gear like British Dragon;
besides saving alot of cash, what differences would there be between you and your brother's results?
