i dont know about noticing cause im mentally chalanged and i see myself skinny no matter how bigger i get, but the weight gains are immediete(spelling sucks on this one imo)
its like - each morning i weight more...
i started 211lbs after a brutal cutting phase and now im 19 days in and i weight around 230lbs so its like almost a pound a day... (doin 30mg dbol a day and 1g of enth in 8 days, so its like 800+ a week i gues)
p.s - 95% of it is water so dont even dream of keeping that weight no matter how much you gain...
