i think that it is person dependant, the actors are possibly on low dose, used in conjunction with fasted cardio and a good diet,.
we know eating clean is a load of mumbo jumbo when gaining on aas and hgh, but when gettiong lean lower carbs, lower salt, 'clean' foods to help contribute to less weight ( water )
i stoped taking HGH on thursday until sunday night, but sunday night i was 6 lbs lighter and my abs were popping.
Water retention is a well known side of any hgh including pharma, it actually says in the leaflet you get with the HOSP grade stuff.
