agree with crid, heck even urologist endo s have tonnes of talks of largest best studies show test is ALOT of marketing hype by such small/poor studies done in clinics or large meta studies of crappy studies. in fact from my limited knowledge there is a larger amount of evidence that topical test is worse than injectable, although marketed as the opposite... I have no idea what mechanism would be Dif other than slightly more pulcitile in nature with cream, perhaps its the levels and how they are metabolized differently. OR just sample bias as biggest and best studies were all done with gels.also these were studies in old men and average was 500 free test but some were upwards of 1000, so maybe it was those that had the plaque and cardiovascular issues within 1 year... also from few people I know on gear they actually tend to have weak stomachs, but also could be diet or may be taking BP or cholesterol meds or shitty protein powder and eat little fibre.... anyhoo on a rant as per usual... .
also 100% hormones/steroids affect intestines. part of why ladies have more issues as hormones change so much(and have 10 extra feet of intestine).. imagine the increase in IGF helps retain thicker stronger/heal faster intestines aswell as water retention, motility, and more likely whatever mechanism the DR suggested in the study...
long and short of it I agree with crid anything to be able to have evidence why they are RXing a compound is what they want ESP when its 100% patient symptom based. like RX weed for sleep and anxiety was great as no longer needed diagnosed glaucoma or HIV just say ur tired... so in this case "my guts hurt I tried 1 other thing and diet change" DR "ok here is a 8 week cycle come back in a few months to see if need to try again" lol
