Currently on a 350 mg test E, 500 mg 1-test cycle. Front loaded both compounds the first week, then 2 week dropped test down to 350. (Originally was sing it at 500 mgs a week with frontload) started two weeks and knew my e2 was wrong. Been using PP aromasin ( on my rats) since day one. Been using 6.25 mgs in the morn an 6.25 mgs at night. E2 came back low! Remind you this is the new stuff with the solution that doesn't hold well and everyone was worried about, needless to say it's legit, gonna have to lower my dose! That's what ur looking for in a peptide company, quality anti E. save you from going under the knife which I unfortunately had to do.
