I was having back acne and terrible anxiety on that E2 number, and I don't get back acne on a normal T protocol. The only times I got back acne was with HCG and on a daily protocol.
With HCG E2 was>100.
With daily E2 was 62.
So that makes sense to me. DHT can't be the culprit, because it was lower on both daily injections and when I was on HCG, when compared to a standard 2x week protocol with only T enanthate.
Total Testosterone by itself either, because it was slightly lower on daily injections and way higher with HCG, when compared to a standard 2x week protocol with only T enanthate.
Given these facts, the only thing consistent that happened when having back acne, was quite elevated E2 at through.
That excludes a lab error.
Regarding Sustanon, if the half life isn't short, why people are injecting it daily, claiming you would have peaks and lows in that way?
