These are two completely different compounds so there isn't much comparison.
I would only use t3 if needed and use diet and training to cut weight. I'm not a fan of using t3, Clen, albuterol.
Ipamorelin is a ghrp(growth hormone releasing peptide). It's good in terms of spiking natural production of GH. Ipam or any ghrp needs to be used in combination with a ghrh (growth hormone releasing hormone). Specifically Mod GRF or also referred to as CJC1295. Make sure you don't get cjc1295 w/DAC, that is for women and mimics their pattern of release of gh.
Mod GRF and ipam in combination will cause a huge spike in natural gh that will peak between 1-2 hours and rapidly decline. A ghrh (mod GRF/cjc) on it's own will do absolutely nothing unless you were lucky enough to inject at the same time as a natural pulse. But the chances are slim and none and slim just left.
The combination of the two is greater than the sum of it's parts. A ghrp, which any can be used and are interchangeable, will produce a slight pulse of gh on it's own. But it's a waste of time and money. Think of the combination as 2+2=10.
When combined they produce a sharp spike in gh output. Exo gh typically peaks around 5 hours and slowly declines, with these you get a big pulse for 1-2 then a sharp decline. The combination is used typically 3 x a day. Usually morning, pwo, pre bed or something similar.
With mod GRF/cjc you use a dose of 100mcg 3 x a day or more along with a ghrp(ipam) dosed from 100-600mcg 3 x a day or more. Most commonly used 3 x a day. You take both at one time in the same insulin syringe, typically Sub Q but can be done IM. IM may speed absorption and peak/clearance so I stick with Sub Q.
The typicall dose on the ipam and any ghrp is/was 100mcg and was thought to be the saturation dose. It's been found that you can use it in higher doses. I usually take 300-600 pwo with 100mcg ghrh. Then 100-200mcg the other two times. It really depends on the quality of the peptide and the amount of money you want to spend.
This combination will be similar to using gh, not exactly the same, but similar. It's you natural gh forced at greater output. But it's not a miracle and you still should use it on a regular, consistent basis for as long as you can to reap the benefits.
Gh works much better in combination with test. At your age it's very possible that you have low T or declining and may want to look into Hormone Replacement Therapy (HRT).
Ipam is a good choice. It's considered the weaker of the ghrps, but nothing noticeable, but also more mild as it won't have any sides. Some ghrps like ghrp6 and hex can increase cortisol and prolactin especially at higher doses, ipam won't. Ghrp2 is also a good choice so I usually just go with what is cheaper.
You need to recobstitute both with 2ml bacteriostatic water and they need to be kept refrigerated.
As far as t3, again I won't use it unless it was need as replacement. You can use peptides and whatever but diet will be key. I would also get on some rear, restrict calories, frequent meals, cardio, and lifting.
