Just wiggle the needle around while u inject if u cough alot it's good
id guess you can make tren ace at 200mg/ml in EO or guaiacol however would take brewing skillsive never seen anyone putting out a legit tren ace upwards of 100mg/ml tbhtren ace crashes at 125mg or so upwards with the standard bb/ba ratioits also EXTREMELY pippy at any more than 100mg/mlif there was legit 200mg/ml tren ace you could tell from the smell and by tasting a drop imo...and because it would give a heavy burning feeling after injecting and heavy pipno company is gonna make a legit 200mg/ml tren ace imo.
