RE: ventipulmin syrup
It appears 1ml = 25mcg clenbuterol. Normal dosing for 20mcg tabs would be:
Start on 1 tab and increase by 1 tab ed until sides become unbearable or to a max of 7 tabs - 2 weeks cycle length in total (no need to taper down). Your 1ml is 25mcg, so a little higher than 1 tab.
Start on 1ml and increase by 1ml ed until you reach 6ml (or lower depending on your tolerance level). Maintain this level for 2 weeks. You can run ECA then for 2 weeks before resuming clen. For the second round of clen, if you finished on 6ml first time (high tolerance) start again on around 2 or 3ml and build up again from there.
