The themogenics continue for a long ass time,im not sure how long,but i know its been shown at least for 26 weeks in one study. The stimulitory effects ease off after a few weeks,but that doesnt mean you stoped burning fat.
Here is one study where EC was administered for 24 weeks...look it shows greatest difference between EC and placebo group between weeks 8-24,so if u were a EC group member of this study and stoped after 8 weeks u would never get to the best period of your cycle, versus not using EC.
"Mean weight losses was significantly greater with the combination than with placebo from week 8 to week 24 (ephedrine/caffeine, 16.6 +/- 6.8 kg vs. placebo, 13.2 +/- 6.6 kg (mean +/- s.d.), P = 0.0015). "

That was just a quote from it,not the whole thing. The combination group took 20mg of E and 200mg of C ,3 times a day for 24 weeks
Heres another one, the subjects were adolescents, this one was over 8 weeks too, i can't find any that were less than 8 weeks

OBJECTIVE: The present study was performed to investigate the efficacy and safety of a caffeine/ephedrine (CE) mixture in obese adolescents. SUBJECTS: Thirty-two (m/f = 16/16) obese children were included into the study. They were treated by diet (calculated daily energy requirement minus 500 kcal) and either CE or placebo (PL) for 20 weeks in a randomized double-blind placebo-controlled trial. Those weighing less than 80 kg took one tablet three times (100 mg/10 mg), whereas those weighing more than 80 kg took two tablets three times per day. There were three dropouts (girls) from the PL group. The age, weight body mass index (BMI) values (mean (range)) of the PL and CE groups were 16.0 (14.3-17.6) and 16.0 (14.2-17.7) y, 103.0 (77.2-126.4) and 104.8 (69.8-150.2) kg, 35.2 (28.3-42.3) and 36.5 (31.3-51.8) kg/m2, respectively. RESULTS: The decrease in relative body weight, BMI and body fat (measured by bioelectric impedance) was significantly (P < 0.05) greater in the CE group (mean +/- s.d.; 14.4 +/- 10.5%, 2.9 +/- 1.9 kg/m2, 6.6 +/- 6.0 kg) than in the PL group (2.2 +/- 5.8%, 0.5 +/- 1.6 kg/m2, 0.5 +/- 2.7 kg). Relative body weight decreased by more than 5% in 81% of the CE group, out only in 31% of the PL group. Adverse events were negligible and did not differ between the CE and PL groups. Withdrawal symptoms were mild, transient and their frequency and severity were not different between the placebo and active groups. CONCLUSION: According to the present pilot study, CE can be a safe and effective compound for the treatment of obesity in adolescents.
So theres no reason to stop before 8 weeks,some people suggest taking a break after 8 weeks minumum,but that doesnt mean you cant go for 24 weeks or longer,there was another study where that was done for one year,and their was only 1 2 week break taken, i think if i was reading it right.
Just wanted to say I made an error on my last post and on the top of this one.when i said 26 weeks,i could only find studies going 24 weeks straight before taking at least a 2 week break,their might be some that go 26 or more straight,but i couldnt find them if they exist.
