I’m not too versed with the M1T, but I am sure that you can run it at 50mg ED for around 6 weeks and same goes for the Winny. I would just watch out for any of the sides that are associated with M1T use and discontinue use if they appear.
Since you live in Brazil can you not go to the pharmacy or a friend and pick up some Test to replace you M1T with? Or just use the M1T as a kickstart for the first few weeks?
From what I have heard from other boards, acquantances and friends who have tried M1T that it isn’t really worth it. Try going another route if you can. I’m not sure why the other poster would choose to do M1T, but decide to stay away from the Winny… but there are sides associated with winstrol use too. Then again, why does M1T have such a bad rep and there are alot more winstrol users out there?
I would also like to state that it would be next to impossible to gain 5 kg in 6 weeks without putting on a kilo or two of fat. A good goal may be .5kg of dry sarcoplasm weekly.
You may also want to post your diet so we can help you stay closer to your no-fat-gain goal. If your diet is up to par you may want to post it anyhow so I and others can gain knowledge from it. You can do so in the Supplements and Nutrition section.
Best of luck!
