The sides from Tbol and hella are very similar and are normally very mild. They're common but not everyone's experience is the same. Back/calf pumps, elevated BP, liver toxicity, lipid strain, suppression/shutdown, even gyno and lethargy and some cases. These are no brainers. Ancillaries and cycle support like forma, n2guard, Tudca and hcgen is a must. As long as those are covered, your experience with these will be a positive one.
