With test, gh, and reta, you have a simple, relatively cheap stack, that can accomplish pretty much 90% of any stacks in the worlds. Want to blast to the moon? Test 300mg->3000mg. GH 3-4 -> 8-12, 3-4 mg of reta and you're set for absurd gains. AIs wont go dry. Neither EQ apparently. The "only issue" will come for reals bodybuilders that competes and cant do it without DHT. That might change a lot of things, especizlly on the amateur scene/non top 50 pros.
For most people, nothing will change, except the fact that "grainy" and that kind of vocabulary will certainly go extinct short-mid terms. Among the trinity, the mist vulnérable one is reta, by a long margin. GH will always be avzilable, some price adjustements period to period. Good fortune time (30 cents the IU) to meh periods (~40 cents IU) to gzrbage time that, at least to a degree will be created by us going full FOMO like the cracks addicts we are and even opti or lobster will be considered cheap.
Reta, on the other hand, could go either extinct or very fucking expensive. If the worse happens, some berberine, jardiance, finerenone and a few pens of log/lantus like the olds days.
