i have always had more side effects with generics that had lower purity/higher dimer.
and ive tried a lot of brands.
Genotropin/optis/qitrope are very clean hghs, low water retention, low joint pain, energy high, not much sleep needed to feel fresh.
mauves are a medium case imo, higher wter retention and more joint pain + ive needed tons of sleep and was still lethargic..
my worst experience was done with pharmatropin, genopharm and another one where ive forgot the name.
TONS of water retention there. My feet looked like elephant feet. Also my joints (esp elbow) was so painful i woke up several times a night due to the pain
