It is truly a jungle out there with all these supps. When I started lifting more serious 13 years ago I tried a lot of supps that had all of these claims of greatness, only to realise non of it really worked or not the worth of their price at least. Then there were several years when I didn't buy any supps other than whey, creatine and vitamins+omega 3. At some point stim stacked pwo's came along.
But I've been getting into supps again the past few years and I think the Industry has evolved a lot. I've been buying stuff mostly as a part of this hobby and when I buy stuff I need I throw in an item or 2 that interests me on top of the order, kind of like just for fun and nothing to loose here. And for my surprise (at first at least) I've actually really enjoyed severel products. Maybe partly cause' at this stage of lifting I have to take any edge/push I can get, but I also think I have found some usefull stuff.
One good sign is allways anecdotal experiences. If a product has hype amongst lifters/end users and the name seems to pop up month after month or year after year, it's defo worth a try imo.
Also I've found the reps in this forum to be very classy, respectful and helpful. Never seen
@Afi140 for example pushing anything worthless just for sales. Help out, tell about options and the sales will follow (if/when products are good) seems to be the way of operate here for many reps. And the reps won't argue or get pissed off if you respectfully tell them that some of theirs product didn't work for you or something. I've personally found several solid products through this forum and with the help of the reps. Iconic Formulations and Iron Legion brands to name some.
Went a bit on a rant here I see which has been happening to me lately, lol. It's this pandemic and staying home most of the time I guess.
