Agreed, all first time Tren users should definitely use the Acetate form because if sides develope and you need to stop immediately it will clear your system quite fast (3 days). The Enanthate form can take weeks or more! I think acetate is stronger having done both. I usually start tren enanthate (which I take for at least 10 weeks)while also taking acetate the first few weeks or month to kick start it, quite powerfull!
