That's genuinely the reason I went with this mix. It puts four peptides together in one shot. The added part isn't something I wanted or needed yet the small cost gap made it worthwhile.
I should add some more details here because I skipped over this part before. When looking at any added nutrients, checking goes beyond just what they contain to include how much is actually there and if the information matches the packaging. For instance, a big serving of muscle building powder listing high protein levels along with carbs just doesn't add up in terms of the totals. Amounts ought to match what studies have used whenever feasible. That's why certain daily vitamin packs come in multiple pills while others fit into one. Regarding the joint support compound I use myself, evidence remains mixed on its benefits. Earlier some arthritis groups suggested it for issues in the lower body joints but have since backed away because the support isn't strong enough. I make sure to use the sulfate form rather than the hydrochloride one. I also came across a recommendation somewhere to quit after six months if nothing improves.
