Probably 350mg a week. Its hard to use alot of because the mg/ml and PIP constraints.
At 350mg weekly though its way stronger than primo at double the dose IMO
I switched from 210mg/wk primo to 105mg/wk DHB back in Sept. My strength increased
significantly within 2-3 weeks after being at a plateau for ages, and I leaned up further. Neither seems useful for E2 control in me, as my aromasin requirement stayed about the same. I dose test fairly low, but do use some of this source's (excellent) TNE as preworkout and libido booster a few days a week, and also use a little MENT, so combined have a decent amount of estrogenicity available.
I have noticed no other effects from DHB - just improved body composition and more strength. Mine is 100mg/ml from a good source (from ASF, not Meso); it has never crashed and is painless. Ive basically tried everything now, and would have to say for me DHB is the most pure anabolic with the fewest collateral effects at least at the very low dose I'm using (I'm 57yo so don't push high mg, prefer to use low mg of more potent compounds).
I posted elsewhere that the 1-methyl group added to DHB to make primobolan significantly attenuates its potency; the compounds are otherwise chemically identical; primobolan is not a DHT derivative, it is a DHB derivative, as is stenbolone (2-methylated as with masteron but with acetate ester). I was very much wanting to try that, but have been told raws have been unavailable for many years. I have some injectable m-sten and it makes a great preworkout, but obviously not something to cycle and grow on.
Primo's 1-methylation may have major effect on aromatase activity in some people, although not me. All the DHT/DHB derivatives have some intrinsic anti-estrogenic effect via diminished ER⍺ transcriptional activity which is why they were (and still are outside USA) used medically as treatments for metastatic ER+ breast cancer. Likely those of us that tolerate higher E2 levels also have higher DHT levels... with lower DHT levels (which can be genetic, those using only HRT/TRT test, or dosing or 5⍺R inhibitors), estrogen over reference range ie >30 tends to cause issues - often with libido/EQ first, then water retention, gyno, acne, mood disorders, anxiety, etc. Those who can run high dose test w/o AI probably have saturation kinetics that favor DHT over estradiol production.
