Of course 150mg of propionate/week puts you way above natural levels.
Molecular Weight (base): 288.429
Molecular Weight (ester): 74.0792
let P = 288/(277+74) ~= 80%
so t = P*150 = 120mg. 120mg per week is about 17mg per day, which is way above any natural production. We don't live in ideal world but at best you produce say 8mg per day, so to make it equal upper range of natural range it would require above 50% waste factor which is highly unlikely.
50mg of prop eod for 8 weeks was considered normal beginner cycle back then in Poland and people had great results with it. I think some of you exaggerate doses greatly. I know guys who looked awesome using 100mg of prop eod and 30mg of wins everyday... and please, they weren't lying, they were consulting the fucking cycle with me.
this is physique on cycle mentioned before, no tren, no gh, boldenone, cypionate (below 500mg) and then prop+wins.
