From my experience with ecdysterone:
first took IDS 17 Hydroxy mesterone with decent results not powerfull results and did the research on ecdysterone from there I researched and found that ants naturally produce ecdysterone and what does this mean:
ants can lift multiple times their bodyweight cant remember the number but it was a long time ago when I read this
so from there I took SciFit ecdysterone which was 300 mg ecdysterone per dose with a high protien meal and it worked better than the IDS product I previously took
I then bought some bulk powder ecdysterone from NP and capped it = similar results to the SCI Fit ecdysterone which I noticed some hardening in my bicepts because Im fat and thats where I noticed it the most
The bulk powder was real gritty and hard to cap and I thought it was a little too expensive to keep on using ecdysterone in any form
so fast forward about a year or so and I found SNI 20 Beta Hydroxy and the supplement facts are as followed:
20 Beta Hydroxy Supplement Facts
Serving Size: 1 Capsule
Servings Per Container: 120
Amount Per Serving
Cyanotis Vaga (Root, standardized 97% 20 Beta-hydroxyEcdysterone) 200 mg
this product worked the best for me as far as ecdysterone goes
I pretty much went from using a small amount with the IDS product to using a larger amount which was 300mg a day to capping my own 500 mg a day to using 800 mg a day with the SNI product and felt similar hardness in my muscles when I used tren xtreme
However I did not in any way double my strength but I did consistently little by little go up in the weight I lifted from week to week but did not plateau like I would usually
Like I said before the ecdysterone products were a bit pricey for me but the SNI product is about 15.00 for 120 caps and I would usually take 4 caps a day
I know I swayed far away from the original question "does ecdysterone come from spinach" and my answer is I dont know, but I just thought I would share my experience on ecdysterone
